Find the best sous-vide machine for your business, by taking into account general and user-specific criteria.

When  **choosing a professional sous-vide cooker** , it is useful to follow  **a set of clear criteria** . Some apply to all models and uses, while others are  **specific to the customer's needs** .

Below, we review them and provide some examples of the  **best models**  for different types of businesses.

# Some criteria for choosing the best sous-vide cooker

One of the very first criteria for choosing a sous-vide machine is  **cooking uniformity** . Thanks to the technology used, this tends to be greater and therefore  **slightly more reliable in stick models** .

Therefore, the most demanding chefs will definitely pick  **an immersion circulator**  instead of a  **static heating tank** . 

Beyond this aspect, there are a number of  **criteria that apply to both types**  of sous-vide cookers:

*  **The accuracy of the temperature** , which should have the  **lowest possible deviation** , ideally  **within 0.2 °C**  or  **32.36 F** . This deviation is called Delta and is indicated by the Greek letter Δ.
*  **The power of the motor** . This determines the amount of water that the appliance can move and heat evenly. In a professional kitchen, models of  **at least 1200 watts**  will almost always be required. A good professional sous-vide machine often has a power rating of  **around 2000 watts** , but the most powerful static tanks can reach  **up to 7500 watts** . 
*  **The quality of the materials and components** . If the elements in contact with the cooking water are made of  **stainless steel** , they offer advantages in terms of durability, hygiene, and cleanliness. The motor must also be of  **high quality** .
*  **Ease of use** . Several elements affect the ease of use of the appliance, first and foremost its  **structure and controls** .

![Picture of a sous vide machine in a restaurant kitchen.](https://sirman-corporate-prod-s3-images.s3.eu-west-1.amazonaws.com/roner_in_un_ristorante_immagine_piccola_1cd9f48a44.jpg)

When it comes to  **ease of use**  specifically, the most advanced models often have  **additional features** . Let's take a closer look at what these might be.

## Special features for an increased ease of use

<a class='css-2qbjsx'  style='color: rgb(20, 145, 155);' href='https://www.sirman.com/en-US/cooking-appliances/sous-vide'>Sirman models</a> and other professional sous-vide cookers have a series of  **features and functions**  designed to make them  **easier to use, clean and set up** , including: 

* The ability to manage the most advanced devices via an app and  **remotely in the cloud** , with stored cooking programmes.
* Sous-vide tanks designed to be  **easy to clean and move** , with facilitated water drainage.
* The ability to control the core temperature via  **wireless probes** .
*  **Safety devices**  to prevent misuse and damage to the appliances.
*  **Touch displays**  that allow you to set the temperature and cooking times precisely and monitor them conveniently.

In addition to these advantages,  **useful accessories**  can be ordered for better management of the sous-vide machine.

## Useful accessories

Sous-vide cookers in the Sirman catalog can be ordered with a number of  **practical accessories** . 

Firstly, our  **immersion circulators** can be purchased together with a  **stainless steel tank** , to be used as a cooking container. The tank has an  **insulated lid**  for energy saving. It can also be supplied with a divider to separate different vacuum bags.

Some  **static heating tanks**  also come with special accessories, such as holders for the touch display, making it easier to read.

# The best sous-vide machine for a small restaurant

Small restaurants with  **limited workloads**  can benefit from an  **entry-level model** . The choice between a static heating tank and an immersion circulator will depend on user preferences. It is important to check the  **capacity** , which for this type of business usually does not exceed  **5 gallons** .

# Michelin-starred restaurants and high-end cuisine

If the service offered is of a high standard,  **an advanced model is preferable** , allowing for  **maximum precision**  in cooking.  **Special features**  designed to facilitate use or to offer  **additional options**  to control temperatures and cooking time, are particularly advantageous in this scenario.

Among Sirman’s models, the perfect choice for these requirements is the  **Softcooker Wi-Food** .

How to Choose a Professional Sous-Vide Cooker

banner_pulizia_affettatrice.jpg

A clean slicer is an efficient slicer. Learn the best practices for maintenance and which models are easiest to clean.

**Slicers**  are an essential tool for a wide variety of food preparations.  **Proper cleaning**  is just as important to ensure that the machines work well and do not contaminate the food.

 **Professional slicers**  used in butcher shops, delis, restaurants, and canteens require  **constant maintenance** , which is simple but must be thorough. The parts of the slicer that come into contact with food must be washed  **daily or several times a day**  if the machine is used intensively.

Proper  **cleaning and sanitizing**  are important for two reasons: the  **efficiency of the machine**  and the  **safety of the food prepared** . Cleaning and sanitizing the slicer properly extends its life, while ensuring cutting precision and excellent quality slices.

# Step-by-Step Cleaning and Maintenance

To  **clean a slicer** , whether it is a professional or domestic model, you should generally follow these steps in order: 

*  **Switch off and unplug the machine**  (if it is an electric model).
* Remove all  **removable parts** .
* Remove any  **food residue** .
* Clean all elements, including the blade, with a  **soft sponge**  and a  **suitable cleaning product** .
* Use the  **lift lever**  to clean the surface on which the machine rests.
* Rinse the surfaces if the cleaning product requires it.
* Wait for the slicer to  **dry** , or dry it with a clean cloth.
* Reassemble and, if necessary,  **lubricate the machine** .

We will explore each step in more detail in this article.

For  **maintenance** , it is also essential to  **sharpen the blade**  and  **lubricate the carriage**  properly and regularly.

 **IMPORTANT** : Before cleaning or servicing a slicer,  **it is crucial to read the instruction manual** . Different machines, especially if they are not from the same manufacturer, may present  **significant differences** , and a procedure that is correct for one model may be  **harmful**  to others.

![Picture of a maintenance kit for slicers.](https://sirman-corporate-prod-s3-images.s3.eu-west-1.amazonaws.com/valigetta_kit_manutenzione_sirman_1ba62e7d1a.jpg)

## When Should You Clean Your Slicer?

In  **professional settings** , hygiene and cleanliness are fundamental for maintenance reasons and to ensure the safety of the food served. A professional slicer must be cleaned  **daily at the end of service**  and before any prolonged pause in its usage. This includes lunch breaks, which, if taken, bring the number of daily cleanings to a minimum of two.

## What Products should be used to Clean a Slicer?

Only  **non-alkaline products**  should be used to clean a slicer, ideally  **without rinsing** , to avoid damaging the appliance. In professional contexts, the hygiene consultant who designs the Food Safety Plan will decide which options are most suitable.

In general, it is possible to clean a slicer with  **alcohol** . It has the advantage of degreasing and disinfecting and then evaporating spontaneously, but it is essential that the alcohol used is  **suitable for food contact** . The pink dye in common cleaning alcohol is  **not suitable**  for food contact, and therefore it cannot be used in professional contexts. However, both in a domestic setting and in professional ones, it is possible to use  **clear white alcohol** , provided it does not contain colorants or other substances that are not certified for food use.

# How to Disassemble the Slicer: Removable Parts

All cleaning operations must be carried out  **with the machine switched off** . Therefore, even though it may seem obvious,  **remember to unplug**  an electric slicer to ensure complete safety.

We recommend  **setting the slice thickness to zero**  before turning off the machine in order to facilitate subsequent operations and work  **in full safety** . The blade thickness gauge will also serve as a protection for the blade wire.

After switching off the machine, proceed to  **disassemble**  all the parts that can be removed. Slicers with removable components make it  **easier to clean**  the machine, but different appliances have different structures. For this reason, you will need to check the  **user manual**  and follow the steps for your model.

In the absence of specific instructions, the  **correct sequence for disassembling a slicer**  is generally as follows: first remove the carriage, then the blade cover, and finally the blade guard.

The  **number of removable parts**  and the simplicity of the operation depend on the model. In Sirman’s slicers, the carriage and all other frequently used parts can be easily disassembled and washed. This also applies to flywheel models.

![Picture of a slicer that has been disassembled for maintenance.](https://sirman-corporate-prod-s3-images.s3.eu-west-1.amazonaws.com/Leonardo_BS_2_Evo_Top_smontata_8e67deae6e.jpg)

# Cleaning the Blade

The  **blade**  is the most important part of the slicer, and it needs to be  **cleaned thoroughly** . It must be wiped, degreased, and sanitized regularly using  **a specific product** , a suitable  **sanitizer**  or hot water and soap.

With a dedicated  **blade extractor** , it can be removed for deeper and more thorough cleaning, but a carefully designed machine always provides the space needed to sanitize the blade quickly and thoroughly without having to dismantle it.

# The Carriage and Machine Body

Once removed, the  **carriage**  can be cleaned separately by following the instructions for the model in use.  **Ceramic-coated carriages**  can be washed under running water or even in the dishwasher.

The  **body of the machine**  does not have to be cleaned as often as the most frequently used parts. However, it is good practice to always  **remove food residues**  with a sponge or damp cloth, as well as to eliminate all residue of detergents and dry the structure thoroughly after each cleaning.

 **The materials and their shape**  determine how easy the machine is to clean. Cleaning and drying  **a rounded surface**  is much easier than wiping the edges and protrusions of square surfaces.

In addition,  **anodized aluminum**  slicers are  **more resistant**  and durable thanks to a greater surface hardness. In this case, the material and the treatment it underwent during production facilitate maintenance.

![Detail of a Sirman slicer carriage.](https://sirman-corporate-prod-s3-images.s3.eu-west-1.amazonaws.com/carrello_affettatrice_per_blog_manutenzione_754c3107dd.jpg)

# Slicer Maintenance: Blade Sharpening and Other Tasks

After cleaning the machine properly, you can proceed with  **sharpening the blade** . This maintenance practice is essential to preserve the quality of the appliance over time, ensuring  **precise cuts**  and  **reduced product waste** . When the quality of the cut decreases and, at the same time, product waste increases, it is necessary to sharpen the slicer.

## How to Sharpen the Blade

To  **sharpen the blade** , set the slice thickness  **to zero**  to ensure maximum  **safety** . This procedure cannot be performed while the slicer is in use, as it is important that the blade is  **perfectly clean**  before sharpening.

 **Mistakes in blade maintenance and sharpening**  are the  **primary cause of malfunctions**  over time. They are not immediately obvious, but they end up having a significant impact on performances. For this reason, it is essential to always carefully follow the  **manufacturer's instructions**  in the user manual and to carry out this procedure with the utmost  **care and attention** .

Depending on the model, the  **sharpener**  may or may not be  **installed on the machine** . Sirman has chosen to install it on all its slicers  **for a number of reasons** . Firstly, having the tool in sight means that the blade will be sharpened more often, and it also avoids the use of sharpeners that are not compatible. Another advantage of this system is that the tool is  **perfectly calibrated**  and adjusted to the machine, avoiding the risk of incorrect positioning.

## How and When to Lubricate the Carriage

While the blade is the main component of the slicer, the  **smoothness of the carriage**  also plays an important role in its use. In professional settings, the carriage of  **small machines**  should be lubricated about  **once a week or every 15 days** , while  **large slicers**  generally have an internal reservoir that needs to be refilled approximately  **once a month** .

The  **food holder and carriage**  of vertical slicers should also be lubricated, ideally after each cleaning.

 **Food-grade oils**  and  **silicone-based spray oils**  should not be used on slicers, as they  **can damage the internal mechanisms**  of the machine and compromise its functioning.

![Oil to lubricate slicers.](https://sirman-corporate-prod-s3-images.s3.eu-west-1.amazonaws.com/ampollina_olio_affettatrici_9961cfcad8.jpg)

# Common Problems: Causes and Solutions

Before getting to the end of this article, let's answer some of the most frequently asked questions about  **machine malfunctions** . Generally, they are caused by  **incorrect or lacking maintenance** .

## Why Does the Slicer Stop while Cutting?

If the slicer  **jams while cutting** , the problem is usually the  **sharpness of the blade** . This is certainly true if the machine can still cut soft products, such as cooked ham, but stops on harder and drier ones.

In some cases, the issue may also occur when the food is too heavy or too large. It is always important to consider the  **cutting capacity**  of the slicer and the  **intended use**  of the model.

In addition, the  **speed of the carriage**  must be proportionate to the product being cut. For soft and small products, it is possible to proceed at higher speeds than for dry products with a large circumference.

## Why is the Slicer Carriage Stiff?

If the slicer carriage is stiff, usually it  **has not been lubricated correctly** . It is also possible that the  **wrong oil**  has been used, one that is not suitable for this purpose. To make it move smoothly again, clean the sliding axles and lubricate the carriage with  **a product specifically designed for slicers** , especially if the machine has not been used for some time. It is also advisable to ensure that the food to be sliced is not too heavy.

## Why Has Rust Formed on the Blade?

Being  **made of steel** , the blade is the only part of an anodized aluminum slicer that can  **rust** . This usually happens due to  **incorrect cleaning and maintenance** . Cold cuts contain  **preservatives and salt** , while meat is corrosive due to the presence of blood. For this reason, as well as for food safety reasons, it is important to  **clean the blade frequently**  and carefully. In retail settings, the use of  **highly concentrated sanitizers**  with incorrect dilution levels can also lead to the formation of rust.

Unfortunately, the only definitive solution in a professional context is to  **replace the blade** , as the presence of rust can pose a food safety  **risk** . Once replaced, it will be important to pay close attention to its proper maintenance.

# Summary

In short, the most critical advice for the correct maintenance of a slicer is to follow the  **instructions provided by the manufacturer**  and included in the  **user manual** . Each model has its own characteristics and requires specific management.

A  **special kit**  is available for <a class='css-2qbjsx'  style='color: rgb(20, 145, 155);' href='https://www.sirman.com/en-US/slicers'>Sirman models</a>, which comes as standard on all TOP models and is optional on others, allowing users to  **perform maintenance activities by themselves** . In addition, the company supports and assists every customer after purchase to ensure that our machines always perform at their best.

The day is almost over, and the brigade is cleaning the kitchen. In the meantime, the kitchen leader is checking **Sirman’s web App** for new notifications. This App manages the appliances connected to the cloud (SRCS - Sirman Remote Control System). The Alpine cheese left to cure in the curing refrigerator is now ready. Tomorrow, they can taste it, and if they’re happy with the result, the kitchen leader can **save the new recipe** - temperature, humidity, and curing period - so it can be used again in the future. The app now suggests that the vacuum packing machine has completed the maximum number of cycles, and it’s time to replace the oil. The kitchen leader can replace it on their day off without interrupting the device’s workflow, **avoiding the risk of an unexpected failure**. 

That’s **how kitchen 4.0 works**. Every appliance is connected to the cloud, recording and sending data, and is managed remotely via computer or smartphone (read <a href='/en-US/press-room/news/future-the-cloud-in-the-kitchen/' style="text-decoration:none;color:#14919B">“the cloud in the kitchen”</a>).

In the past few years, digitisation has become part of the kitchen, bringing some excellent advantages. Let’s see them in detail.


## Why use data and digital technologies in the kitchen?
    
Today, **digitisation has become essential in many sectors**. Digitisation also means collecting data concerning your business and equipment and using them efficiently.

Therefore, the technologies that allow us to use these data **help promote intuition, talent, and entrepreneurial skills**. And this applies to professional kitchens as well. Let’s see why.

Data help keep the appliances’ operation always under control. How is the appliance working? Does it have worn out components? How much energy is it consuming? Knowing this information helps kitchen owners with **preventive maintenance**. By setting proper alarms on the app, you can be notified when a component is worn out, and thus prevent failures and downtime. This way, you can replace the component when the restaurant is closed without stopping the device’s operation.
    
![iot_fondo web.jpg](https://sirman-corporate-dev-s3-images.s3.eu-west-1.amazonaws.com/iot_fondo_web_ce44c49ab4.jpg)

For example, if you know that the grater roll must be replaced after **500 operating hours**, you can set the alarm on the app to be notified when this threshold is reached. This way, you can check whether the roll needs to be replaced for yourself.

Setting alarms and thresholds for cloud-connected appliances can make your life in the kitchen much easier. You can **automate many operations**, block the appliance automatically to prevent damage or promptly signal a failure. For example, if water remains in the softcooker once the food is ready and you don’t prepare anything else afterwards, the appliance emits a long beep. This signal allows you to promptly remove the water and prevent damage or blocking the dough mixer if the motor is overheating.

Having as much data as possible is essential even when you have to **ask for remote assistance**. Sirman’s operators analyse the data collected by the appliances’ sensors to understand whether the problem depends on their usage or a technical issue. This way, they can help you find a solution.

Moreover, **monitoring an appliance’s energy consumption** allows the kitchen leader to quantify the related costs.

![telefono montaggio.jpg](https://sirman-corporate-dev-s3-images.s3.eu-west-1.amazonaws.com/telefono_montaggio_79eb5a5fe7.jpg)


**In brief**, smart kitchen appliances help the brigade:
<div align="left" style="padding-left:10%;">
<p style="padding-bottom:5px;">☑️&nbsp;&nbsp;carry out **preventive maintenance**</p>
<p style="padding-bottom:5px;">☑️&nbsp;&nbsp;<b>automate operations</p>
<p style="padding-bottom:5px;">☑️&nbsp;&nbsp;**stop the appliance automatically** before causing irreparable damage</p>
<p style="padding-bottom:5px;">☑️&nbsp;&nbsp;La <b>signal failures in real time</p>
<p style="padding-bottom:5px;">☑️&nbsp;&nbsp;Inspect the appliance and ask for **remote assistance**</p>
<p style="padding-bottom:5px;">☑️&nbsp;&nbsp;**Monitor the consumption** of every appliance</p>
</div>

As the appliance gets easier to control, interaction becomes more immediate. Sirman devices can be connected to Amazon smart speakers, which allow the kitchen leader to give voice commands to the appliance through Alexa.


##Why should a professional kitchen be connected to the cloud?

The **cloud** is where all these data are stored. It’s an agile infrastructure with a high storage capacity. Sirman’s appliances rely on Amazon Web Service, Amazon’s spin-off dedicated to all-things data and IoT.

Remember! The cloud is the **shared data storage of your professional kitchen**. Let’s see a few examples.

Sirman’s SRCS catering appliances are connected to the cloud, which kitchen leaders can access through the app. Therefore, you only need **one device** (a smartphone, tablet, or computer) **to control all kitchen appliances**. That’s what we call a huge advantage.

This means that **one recipe can be shared by several appliances**. For example, a curing recipe can be launched on several curing refrigerators simultaneously. Sirman’s appliances can **save thousands of recipes** in the cloud, unlike traditional kitchen appliances, which can save only a few.
Moreover, you can **start a recipe remotely or delay its launch**. Therefore, the owner of several restaurants can have one digital place to store the most successful recipes.


![iot_prod.jpg](https://sirman-corporate-dev-s3-images.s3.eu-west-1.amazonaws.com/iot_prod_d229f7808a.jpg)

In addition, our **online community of chefs** shares the best recipes for Sirman appliances. Are you tempted to try some?





The cloud kitchen: a recipe for success

cover-cloud-cucina.jpg

Sirman is one of the first companies to use cloud technology in kitchen appliances. The company has developed a number of cloud-connected appliances that can help to improve the efficiency and productivity of kitchens.

Sirman believes that cloud kitchens are the future of food service. The company is committed to developing innovative new products that will help to make cloud kitchens even more efficient and cost-effective.

cover-mobile-cloud-cucina.jpg

As of today, **50% of Sirman’s professional equipment for the Ho.Re.Ca sector, large-scale distribution, and workshops can become smart**. The operator can:
<div align="left" style="padding-left:10%;"><p style="padding-bottom:5px;">
☑️&nbsp;&nbsp;control the appliances remotely</p>
<p style="margin-bottom:5px">☑️&nbsp;&nbsp;automate operations</p><p style="margin-bottom:5px">☑️&nbsp;&nbsp;monitor energy consumption and the state of wear of components</p>
<p style="margin-bottom:5px;">☑️&nbsp;&nbsp;save thousands of recipes or start the best ones among those shared in the community.</p>
</div>

These are just a few advantages you can get by using the cloud in the kitchen. Let’s see how Sirman has become **one of the first companies to use this technology and what’s behind it.**


##At the forefront of professional, smart cooking


Sirman has always been committed to innovating its products. In 2009, **Sirman showcased the first remote-controlled catering appliances** at Host, Milan’s trade fair dedicated to hospitality.

Over the subsequent years, the company developed more advanced technologies tested on specific products. Sirman’s innovation team was driven by the idea of finding a **technology to record and transmit the appliances’ data**. At the same time, the end-user had to **use them effortlessly**.

In 2015, for example, the company launched a <a href='/en-US/cooking-appliances/softcooker/softcooker-wi-food/69400002' target="_blank" class="css-2qbjsx" style="color: rgb(20, 145, 155);">Softcooker</a> that exchanged data via Bluetooth. However, the user had to stay near the appliance, so it wasn’t the **remote-controlled** solution Sirman was looking for yet, but it already allowed the operator to control it via the app, improving the user experience and expanding the display functions.

##The turning point: a technological change and the ambition of a single management platform.

In 2017, Sirman started thinking about the WIFI technology used for the Internet as a possible solution. That year, they prototyped a smart vacuum packing machine using WIFI technology. It was a good start in the right direction. These years also marked the beginning of a partnership with Amazon Web Service (AWS), Amazon’s spin-off dedicated to all-things data and IoT. This way, Sirman has developed hardware compliant with AWS services and IoT standards and a cloud system for collecting and using data through AWS. That’s how <a href="//srcs.sirman.com" class="css-2qbjsx" style="color: rgb(20, 145, 155);">SRCS</a> came to life. SCRS stands for **Sirman Remote Control System** and is used to manage all Sirman appliances.

##Using the cloud technology in the kitchen, thanks to Sirman

By 2020, Sirman could make most of its appliances smart and cloud-connected. Today, every product in Sirman’s catalogue, including **dough mixers, vacuum packing machines, softcookers, and slicers**, can benefit from the cloud. This technology can be applied to 80% of Sirman’s kitchen appliances. However, small, and more affordable devices are the exception since the former doesn’t have the room to house this technology and the latter wouldn’t justify the investment in the cloud.

How do smart catering appliances work? **The technology behind these products is the Internet of Things (IoT)**. The idea behind the IoT is that the Internet connection can be shared and extended to the other tools and equipment we use on a daily basis, from home heating to catering machinery. This way, we can manage most of our daily actions remotely, automate several operations, and monitor everything through data. In brief, IoT’s goal is to increase efficiency and productivity and make users’ life easier.


##The partnership with Amazon Web Services: the chip that makes Sirman appliances smart

**A special chip interacting with AWS’ IoT services** makes Sirman's appliances smart.
**Every appliance is fitted with special sensors** to collect essential data (e.g. motor temperature, humidity in the curing refrigerator, or the number of slices a slicer has made) and monitor relevant parameters.
Small electronic control boards (chips) installed in the appliances collect these data and **send them to the cloud**, an AWS-managed infrastructure. Once saved, users can read these data to **control and monitor the appliance remotely** via the Internet.

Therefore, the kitchen staff can control, monitor, and automate an appliance from a computer or smartphone. And those who want to have a unique assisted experience can call **Alexa**. Sirman’s interest in investing in new technologies led it to create a Sirman skill on Alexa – the famous **voice-controlled virtual assistant** – to allow users to control Sirman’s appliances with their voice.

Cloud kitchens: the future of food service?

w_softcooker-cover.jpg

Who hasn’t heard of sous-vide cooking? After its debut in the kitchens of starred chefs, sous-vide quickly conquered the entire restaurant industry, making it indispensable, from luxury restaurants to catering services. 

But what are the advantages of a technique that up to a couple of decades ago was available only to an exclusive niche?

##1. Quality of dishes: enhanced flavours and consistent texture

Sous-vide cooking prevents food liquids from evaporating, thus preserving its natural fragrance. Moreover, preparing marinated and seasoned food combining sous-vide with slow cooking enhances aromas, whereas low temperatures preserve the food’s nutrients.

But there’s more. Sous-vide cooking ensures excellent texture, which traditional methods don’t often achieve. This aspect particularly applies to meat, where extended cooking times allow for a soft and juicy texture, even in less valuable and tender cuts.

![pepe_gallina-disossata.jpg](https://sirman-corporate-dev-s3-images.s3.eu-west-1.amazonaws.com/pepe_gallina_disossata_cb9c0652a0.jpg)

##2. Ease of use: consistent temperatures and reliable results

Temperatures and cooking times are different from traditional ones and need specific recipes(<a href='https://srcs.sirman.com/' style='color:#14919B' target="_blank">SRCS</a>) and some habit changes. Since sous-vide enhances flavours, it’s important not to overdo it with seasoning and marinating.

However, life gets easier if you have a sous-vide recipe book. In professional machines, the temperature is set with extreme precision; it spreads evenly and is monitored consistently for reliable results every time. Moreover, sous-vide cooking minimises waste resulting from errors or minor occurrences and maintains the quality of the dishes.

##3. Optimised work schedule

It’s true, sous-vide cooking can take longer than traditional methods. However, its ease of use and preservation options allow you to manage work more efficiently and be more productive.

Sous-vide requires minimum supervision, allowing you to do other activities. You can even monitor the appliance remotely if the machine is managed via an app like  <a href='/en-US/cooking-appliances/softcooker/softcooker-wi-food/69400002' style='color:#14919B' target="_blank">Softcooker Wi-Food SIRMAN</a>.

![iot-landing-01.jpg](https://sirman-corporate-dev-s3-images.s3.eu-west-1.amazonaws.com/iot_landing_01_a91ab14afc.jpg)

At the same time, you can also programme the preparation of your dishes. Moreover, once the sous-vide procedure is complete, you can blast chill cooked food and store it for a few days without altering its organoleptic properties. Then, briefly brown the dish on a grill or in a frying pan before serving or heat it in the oven for a perfect result.

##4. No waste with sous-vide

The cost of sous-vide machines is irrelevant. They can even make you save money, especially in kitchens that work with large amounts of food.

Dishes prepared using conventional techniques suffer a weight loss that can reach and sometimes exceed 20% of the product. By using the sous-vide method, this drop in weight is almost null. Of course, this will result in huge savings over large volumes and long periods of time.

##5. The safety

A <a href='/en-US/packaging/vacuum-packaging-machines/w8-top/S3330221008BX2/' style='color:#14919B' target="_blank">professional sous-vide machine</a> allows for almost total vacuum, preventing bacteria proliferation and ensuring safe food and long shelf life. A further assurance for safe food preparation is the potential for total temperature control and the certainty of homogenous cooking.

Sous-vide appliances can cook fresh food without any risk and, indeed, ensures very high safety and quality of dishes.

In other words, the sous-vide technique is so successful because of its versatility and ease of use. Moreover, it ensures quality and cost-effectiveness, making it an indispensable tool in any professional kitchen.

How to choose a vacuum machine: types, uses, and distinguishing features

##Uses of a vacuum packing machine

Professional kitchens use vacuum packing to preserve food and prepare it for sous-vide. In both cases, the procedure is the same, but the type of pouches is different, depending on the food you want to cook.

![ambientata Softcooker Wi-Food SR BI_sottovuoto.jpg](https://sirman-corporate-dev-s3-images.s3.eu-west-1.amazonaws.com/ambientata_Softcooker_Wi_Food_SR_BI_sottovuoto_17f4d61a17.jpg)


Because of the low temperatures and long cooking times involved with sous-vide, achieving a near-complete vacuum seal is crucial.

##What vacuum packing machine should you buy?

A professional vacuum packing machine is essential, regardless of the sector. Domestic appliances can rarely achieve a vacuum percentage higher than 85%. As high as this may sound, vacuum levels above 99% are necessary for the best food preservation, particularly for sous-vide cooking. Only a near-complete vacuum seal can stop bacterial proliferation and preserve food safely, even for long periods.

So how do you recognise the ideal machine for your needs? The market offers two types of vacuum packing machines:

##Edge vacuum machines

Edge vacuum machines are not ideal for sous-vide cooking in a professional kitchen. They are mainly used as foodsavers to extend the food’s shelf life.

Depending on the model, edge vacuum sealers can ensure a relatively high vacuum percentage. However, chamber vacuum sealers are preferred in a professional kitchen as they are more efficient and versatile.


##Vacuum chamber machines

Vacuum Chamber Machines meet catering needs because they can ensure almost 100% vacuum. They consist of an inner basin, called a chamber, and a lid with a characteristic bell shape.

![VACUUM_PACKAGING_MACHINES_EASYVAC_TOUCH_CE.jpg](https://sirman-corporate-dev-s3-images.s3.eu-west-1.amazonaws.com/VACUUM_PACKAGING_MACHINES_EASYVAC_TOUCH_CE_d6d2bff75c.jpg)

These models ensure reliability and a high vacuum percentage. In addition, they allow you to process large volumes of food. Chamber vacuum sealers are suitable for preserving liquids and friable food.


##Other criteria to take into consideration

Before you buy an edge or chamber vacuum sealer, you should consider some additional factors related to your needs and machine management. Let’s see a few of them:

### Inert gas option

Some models can seal food in a protected atmosphere using inert gas. This function is essential for sealing friable and delicate food, which would be crushed as soon as air is removed from the pouch. Inert gas (usually nitrogen) replaces the air in the pouch, creating an environment as safe as vacuum. 

### Oil pump or dry pump

Vacuum packing machines using a dry pump are less efficient and achieve lower amounts of vacuum than oil pumps. There are different types of oil pumps based on their power and brand. For example, DVP and Busch are some of the most reliable oil pump manufacturers. Their models ensure high power and create vacuum quickly and efficiently.

###User-friendly software and commands

Sirman’s vacuum packing machine is easy to use because of its software and commands. Choosing the appliance that meets your needs with functional commands is essential.

![touch_w8.jpg](https://sirman-corporate-dev-s3-images.s3.eu-west-1.amazonaws.com/touch_w8_59ecfef0bb.jpg)

SIRMAN’s most advanced models are fitted with artificial intelligence to automate some steps, including setting the vacuum time. Moreover, they alert users when it’s time for maintenance, i.e. changing the oil or calibrating vacuum sensors.

###Cleaning and maintenance

A vacuum packing machine must be regularly cleaned and serviced to ensure maximum efficiency and safety. Changing the oil is a crucial step that is usually done by certified personnel. However, with some models, users can do it too. To make this process simpler, a SIMRMAN-patented option allows users to change the oil automatically by connecting the machine to an external tank.

The ease with which these steps can be performed will influence your choice, positively impacting costs and the user experience.

Learn about 7 key points to help you choose the best model for your business’ needs.

Many criteria come into play  **when choosing a professional slicer** . The worker's needs and preferences are just as important as  **the intended use**  of the machine and the  **type of food**  that will be sliced.

For this reason, there are  **different types of slicers** . Over the years, models have been modified, adapted, and perfected to meet every user’s needs. Below, you will find  **an overview of professional slicers and their strengths**  to help you in your choice of a new appliance.

# The essential features of a slicer

In this blog post, we will discuss  **seven important criteria for choosing a slicer** . Before reviewing them, let's briefly look at  **some essential features of a high-quality model** :

*  **Safety** : Every slicer should have  **safety features**  to  **lock the blade and carriage**  in case of accidents or assembly errors.
*  **Motor and blade quality** : It is important to check the  **quality of the motor** , especially if you intend to use the appliance intensively. For a good domestic model, 100 watts may be sufficient. A  **professional slicer** , on the other hand, must have a power rating of  **at least 150 watts** . In the case of slicers for  **intensive use** , a more powerful motor is preferable, which can reach  **up to 400 watts** .
*  **Material quality** : Slicers made of  **anodized aluminum**  are by far the most durable and resistant, especially if manufactured with  **gravity casting** .
*  **User-friendliness** : A professional slicer that is frequently operated must be  **easy to use, dismantle, and clean** . The  **sharpener** , which ideally should be installed on the machine itself, should also be easy to handle.

Most  **professional slicers**  meet these requirements, but it is good practice to verify before making a purchase. In domestic models, these features can not be taken for granted.

In the following paragraphs, we will list  **other key criteria**  that are linked to the  **user’s needs**  and to the **specific features of the business**  or  **the products to be sliced** .

# 1. The speed of the slicer
 
 **Working speed**  is an important factor in supermarkets, canteens, or restaurants with many tables, and  **slicing accurately and quickly**  is the main strength of a  **gravity slicer** . 
The  **angle of the blade**  allows the product to slide down the surface on its own while being sliced. A  **higher or lower angle of inclination**  is a subjective choice influenced by various factors: the posture of the worker, the amount of space available to store sliced products, and the speed of execution. The more a blade is inclined, the more the product slides towards it, thus facilitating and speeding up the cutting process.

Our  **Palladio**  model is a gravity slicer designed for large-scale food services. It has  **rounded shapes**  to facilitate and expedite cleaning operations and is made of  **cast aluminium** .

 **Gravity casting**  requires a high amount of molten metal compared to what will constitute the final machine. Additionally, in order to proceed to the final anodizing stage,  **high-quality alloys**  must be used. The result of the process is a superior type of aluminum that is suitable for food contact, clean, durable, and homogeneous, with  **increased surface hardness and strength** .

# 2. The precision of the slicer

 **Vertical slicers**  are a  **high-end product** . These models rely on  **a more complex technology** , as they have two plates to move the product rather than just one. Food items are secured on the first plate and then slid along thanks to a second support surface. The portion of the product to be sliced is pushed out from the plate each time a new cut is made.

Because of this technology,  **vertical slicers allow for greater precision** . The manual push tends to produce more consistent cuttings and is suitable for users who want to obtain  **slices of a very precise thickness**  even on large products. These slicers are also  **ideal for intensive use** , as they allow the worker to maintain a comfortable posture and avoid bent positions, which are uncomfortable in the long term.

Our  **Mantegna**  model is a  **high-end vertical slicer**  designed primarily for restaurants. It stands out through its rounded shape and is made from  **cast anodized aluminum** , which is then treated with an electrolytic process. This increases the machine's  **resistance to rust**  and makes it suitable for food use. It is also equipped with an  **on-board sharpener**  to facilitate and speed up sharpening operations.

# 3. Blade and carriage performance

The  **diameter of the blade**  is the main factor determining  **the slicer's cutting capacity** . Depending on the food to be sliced, larger or smaller blades may be required, with  **sizes ranging from 7.8 to 15 inches** .

For foods with a particularly  **large circumference or high weight** , such as certain types of mortadella, it is important to choose blades with a diameter of  **13.7 inches or above** . They also require high-performance, smooth-running carriages.

Many models allow blades of different sizes to be fitted, but it is important to note that  **cutting capacity also depends on the size of the appliance and the carriage** . A larger blade allows for a greater cutting height. However, if mounted on a slicer that is too small, in some cases it can lead to a reduction in the available length and therefore to an unchanged or reduced cutting capacity.

Some SIRMAN models can mount  **blades of different sizes** , but they are specifically designed to avoid a reduction in cutting length when larger blades are used.

The  **ideal SIRMAN slicers for heavy foods**  and for products with a large circumference are the  **Leonardo and Galileo models** , which can be fitted with blades measuring  **13.7, 14.5, and 15 inches** . They also feature high-quality carriages, which remain smooth-running even under weights of 10 kg and above.

# 4. The aesthetics of the appliance
 
 **Manual flywheel slicers**  are fascinating machines. When prominently displayed in restaurants, they encourage customers to order dishes that require their use. At the same time, their clean lines conceal  **great technical complexity** . In fact, the flywheel slicer is  **activated by hand** , by turning the flywheel connected to the blade and carriage. The blade rotations then advance the carriage at a fixed ratio.

Flywheel slicers are  **precise and functional** , but the reason for choosing this type of machine over others is linked to aesthetics. Recently, a  **trend for Italian charcuterie**  has been spreading abroad, in the form of delicatessen counters that evoke nostalgic atmospheres. Flywheel slicers are ideal for this context. Being  **complex machines** , they are recommended for activities that involve cutting the same type of product for extended periods of time.

# 5. Small slicers for limited spaces

For a business with  **limited space** , where the slicer will not be used intensively, a  **small model**  is ideal. Before purchasing, you should check  **the size of the assembled appliance** , bearing in mind that there must be a minimum gap of 4 inches from adjacent walls. This allows for proper ventilation. 

All Sirman slicers are designed to be placed on the  **typical tables**  used in the catering industry, but our catalog also includes smaller models.

The  **Mirra**  model is a small, compact, and minimalist  **professional slicer** . It is an electric machine, which can be conveniently positioned even in very small spaces. Practical and easy to handle due to its size, it is the best slicer for cafés, bistros, or small restaurants.

In Northern Europe, this model is highly appreciated in  **shops and convenience stores**  because it can slice  **small salami and charcuterie**  while still allowing for medium-intensity use. Like most of Sirman’s professional slicers, the Mirra model is made of cast aluminum, which is anodized in the final stage of production.

# 6. The food to slice: not just meat and cold cuts

For products other than meat and cold cuts, there are special  **serrated or Teflon-coated blades** . Additionally,  **ceramic-plated options**  are particularly useful for products like cheese, which tend to stick and slide with difficulty at high temperatures. The version of Sirman slicers with ceramic-coated blades is called the  **Stonehenge line** .

In addition,  **plates designed specifically to hold different products**  are available for some of our slicers, like the  **Palladio model** . For vegetables, we created the  **Food Tube 2.0** , an accessory that makes it possible to cut several products at a time. 

# 7. IoT technology

 **IoT technology**  can be applied to Sirman slicers, starting from medium-sized ones. This choice improves functionality without affecting the intuitiveness and simplicity of the machine. It monitors  **all machine usage metrics** , including time, ampere consumption, and motor temperature. Therefore, it makes it possible to  **manage maintenance activities**  or the replacement of wear parts, such as blades or grinders, before any shutdowns occur. It also features an  **automatic shut-off function** , as slicers are quiet appliances that are often left on.
