Quick Freezing mode in the refrigerator: what is it, why is it needed and how to use it

You opened the instructions for the new refrigerator, and among the many functions you came across a mysterious one Quick Freezing - what kind of mode it is, and Why is it highlighted as a separate button or menu item? In short: this is a technology emergency freezingthat in a matter of hours reduces the temperature in the freezer to record values ​​in order to freeze fresh food as quickly and efficiently as possible. But why is this necessary if the freezer already operates at -18°C? It turns out that the normal mode does not always cope with the task of preserving taste, texture and nutrients - especially when it comes to berries, green vegetables or fresh fish.

In this article we will look in detail at how it works Quick Freezing (it is also called Super Freeze, Power Freeze or Fast Freeze depending on the brand), when to turn it on, and when it only wastes electricity. You will learn which foods really need to be quickly frozen, and which can be safely frozen as usual. We will also explain why this mode cannot be kept on all the time - and what will happen if you ignore the manufacturer’s recommendations. For clarity, we will provide a comparative table of temperatures and freezing times, and at the end we will answer the most frequently asked questions from users.

What is Quick Freezing and how does it work

Mode Quick Freezing (translated as “quick freezing”) is a function of modern refrigerators that temporarily lowers the temperature in the freezer camera up to -24°C…-32°C (depending on the model) instead of the standard -18°C. The main goal is to instantly freeze foods while keeping their cells intact. The fact is that during slow freezing, large ice crystals form inside the food, which break the cell walls. As a result, after defrosting, vegetables become soft, meat loses juice, and berries turn into porridge.

In mode Quick Freezing the process happens differently: the temperature drops so quickly that the water in the food freezes almost instantly, forming microscopic crystals. This preserves tissue structure, color, taste and even some vitamins. For example, strawberries frozen in this mode will remain firm and juicy after defrosting, and fish fillets will not lose their shape.

• ❄️ Temperature range: from -24°C to -32°C (versus -18°C in standard mode).
• ⏱️ Operating time: usually 2–24 hours (automatically turns off or requires manual shutdown).
• ⚡ Energy consumption: increases by 10–30% during operation of the mode.
• 🔄 Frequency of use: no more than 1-2 times a week for most models.

It is important to understand that Quick Freezing is not a permanent mode, but a temporary function. Once the cycle is complete, the refrigerator returns to normal temperature. In some models (for example, Samsung or LG), the mode turns off automatically after 24–48 hours, in others (like Bosch or Liebherr) it must be turned off manually.

Why do you need the Quick Freezing mode: 5 real reasons

Many users mistakenly think that Quick Freezing is needed only for “lazy people” who don’t want to wait. In fact, this mode has specific tasks where it is truly indispensable. Here are situations in which you cannot do without it:

1. Freezing berries and fruits. Raspberries, strawberries, cherries and other juicy fruits stick together into a lump when frozen slowly and lose their shape. Quick freezing keeps them whole - ideal for compote or desserts.
2. Fresh fish and seafood. Salmon, shrimp or mussel fillets spoil in a few hours at room temperature. Quick Freezing stops the growth of bacteria and maintains a delicate texture.
3. Greens and vegetables for long-term storage. Parsley, dill, spinach or green beans become limp in a regular freezer. Quick freezing locks in their freshness.
4. Meat and poultry before portioning by slicing. If you freeze a large piece of beef or pork in this mode, it will be easier to cut it into thin slices (for example, for barbecue).
5. Home-made semi-finished products. Dumplings, dumplings or cutlets, frozen quickly, will not stick together and will retain their shape when cooked.

There are also less obvious cases. For example, if you buy fish or meat (not frozen!), and it takes more than an hour to get home, turn it on in advance - this will prevent spoilage of the product. The same applies to seasonal preparations: if you brought a kilogram of fresh currants from the market, it is better to immediately freeze them in this mode, and not leave them in the main chamber “for later.” chilled fish or meat (not frozen!), and it takes more than an hour to get home, turn on Quick Freezing in advance - this will prevent damage to the product. The same applies to seasonal preparations: if you brought a kilogram of fresh currants from the market, it is better to immediately freeze them in this mode, and not leave them in the main chamber “for later”.

How to use Quick Freezing correctly: step-by-step instructions

It would seem complicated - put the food in, press the button, ready! But for the regime to work effectively, you need to follow several rules. Errors here can lead to excessive energy consumption or, conversely, to incomplete freezing. Here is the algorithm of actions:

Pack food in sealed bags or containers|

Lay out food in one layer on a wire rack|

Remove excess food from the freezer for better air circulation|

Enable Quick Freezing for 1-2 hours before adding food (if there is such an option)|

Do not overload the freezer (maximum 2/3 of the volume)-->

Now more details about each step:

1. Packaging. Use vacuum bags, cling film or containers with a tight lid. The main thing is to minimize the access of air in order to avoid frostbite (drying) of products.
2. Layout. Do not dump everything in a heap! Place the food in a single layer on a wire rack or baking sheet to distribute the cold evenly. For example, berries can be frozen on a tray and then poured into a bag.
3. Temperature shock. If your refrigerator supports pre-cooling (for example, Liebherr has an option SuperCool), turn it on an hour before adding food. This will speed up the process.
4. Operating time. Usually 2-4 hours are enough for complete freezing. Some models (for example, Samsung RB30A3200SA) automatically turn off the mode after 24 hours, but it is better to monitor the process.

Please note: if there are already food items in the freezer, their temperature will temporarily rise when loading a new batch. Therefore, do not put in Quick Freezing along with already frozen products something sensitive to changes (for example, ice cream).

What will happen if you leave Quick Freezing turned on for a week?

Long-term operation in this mode will lead to:

1) Significant increase in energy consumption (up to 40% higher than usual).

2) Overloading of the compressor, which shortens the life of the refrigerator.

3) Formation of excess frost on the evaporator (even in models with No Frost).

4) Freezing of products - some (for example, sauces or semi-finished products) may lose texture.

In most modern refrigerators, the mode automatically turns off after 24–48 hours, but in older models it must be turned off manually!

Comparison of Quick Freezing with regular freezing: which is better

To understand whether it is worth using Quick Freezing, let's compare it with the normal mode in key parameters. For clarity, we have collected the data in a table:

The table shows that which Quick Freezing wins in speed and quality, but loses in efficiency. Therefore, it is rational to use it only for fresh products that are planned to be stored for no longer than 2-3 months. For long-term storage (for example, meat for six months), the usual mode is sufficient - the main thing is to pack the food correctly.

Another nuance: in refrigerators with the system No Frost Quick Freezing it may work less efficiently than in models with drip defrosting. The fact is that No Frost constantly pushes air through the evaporator, which slows down the cooling slightly. However, the difference is not critical - only 10–15 minutes.

Common mistakes when using Quick Freezing

Even experienced housewives sometimes make mistakes that negate all the benefits of quick freezing. Here are the most common of them:

• ❌ Overloading the freezer. If the chamber is filled to capacity, cold air will not circulate and the food will freeze unevenly. The optimal load is no more than 2/3 of the volume.
• ❌ Using inappropriate containers. Plastic bags with holes or open containers will lead to frostbite of the food (they will dry out). Use only airtight packaging.
• ❌ Freezing hot foods. By putting hot soup or roast in the freezer, you will not only increase the freezing time, but also risk raising the temperature of the food already in there. Cool the food to room temperature!
• ❌ Ignoring the timer. In manual models, you need to turn off the mode yourself. If you forget, the compressor will wear out, and the electricity bill will increase.
• ❌ Frozen products with high water content. Cucumbers, lettuce, watermelon - they should not be frozen even in the Quick Freezingmode, since after defrosting they turn into porridge.

A separate point - defrosting products frozen in this mode. They should not be thrown into the microwave or hot water! It is better to transfer to the main chamber of the refrigerator for 6-8 hours or use the function soft defrostingif it is in your model.

Quick Freezing in refrigerators of different brands: features

Manufacturers call this mode differently and introduce additional features. Here's how it's implemented in popular brands:

• 🔹 Samsung: Power Freeze — lowers the temperature to -32°C, works up to 72 hours (automatic shutdown). Available in models Family Hub.
• 🔹 LG: Express Freeze - freezing in 1 hour, but only in freezers with Inverter Linear Compressor.
• 🔹 Bosch: SuperFreezing - temperature -24°C, turns off automatically after 6 hours.
• 🔹 Liebherr: SuperFrost - one of the most “smart” systems: it determines when the food is frozen and turns off.
• 🔹 Indesit/Hotpoint-Ariston: Fast Freeze —a budget option, works up to 24 hours, but only lowers the temperature to -24°C.

In premium class refrigerators (for example, Samsung Bespoke or Liebherr Premium) the mode Quick Freezing can be combined with other functions, for example:

• CoolSelect Zone (y Samsung) - a separate compartment with adjustable temperature, where you can quickly cool or freeze food.
• BioFresh (y Liebherr) - a combination of quick freezing with humidity control for greens and fruits.

If your refrigerator is older than 5 years, it may not have a full-fledged Quick Freezingbutton Super or Turbo - it performs the same function, but less effectively. Check the instructions!

How to find out if Quick Freezing is in your refrigerator?

1. Look at the control panel - look for a button with the inscription Quick Freeze, Super Freeze or a snowflake with lightning.

2. Take a look at the instructions (section “Special functions”).

3. If there is no button, but there is a Super or Turbomode, it can work similarly.

4. In modern models, the function may be hidden in the menu - for example, in Samsung it is enabled via Settings → Freezer → Power Freeze.

What happens if you use Quick Freezing incorrectly: consequences

It would seem that there is something bad about to leave the mode on longer or to freeze everything in it? In fact, the consequences can be serious - both for the food and for the refrigerator itself.

⚠️ Attention: If your refrigerator does not have an automatic shut-off Quick Freezingnever leave it running for more than 24 hours. This can lead to overheating of the compressor and breakdown, which is not covered by the warranty (since this is a violation of the operating rules).

This is what happens when the mode is abused:

• 🔋 Increased wear of the compressor. Working at maximum power reduces its life by 15-20%. On average, the compressor is designed to last 10–15 years, but with constant Quick Freezing may fail in 5–7 years.
• ❄️ Ice formation even in No Frost. In models with No Frost with long-term Quick Freezing frost may build up on the evaporator, which will lead to a failure of the auto-defrost system.
• 💰 Increase in electricity bill. For example, a class refrigerator A+++ in normal mode consumes ~300 kW/year, and when constant Quick Freezing - up to 450 kW/year (50% more!).
• 🍓 Product spoilage. Some products (for example, sour cream, mayonnaise, sauces) at ultra-low temperatures separate or change consistency.

Another danger is thermal shock for glass and plastic. If you put a glass jar with liquid (for example, broth) in the freezer and turn it on Quick Freezing, the jar may burst due to a sharp temperature change. The same applies to low-quality plastic containers - they become brittle and crack.

⚠️ Attention: In refrigerators with one compressor (for example, in budget models ATLANT or Birusa) mode Quick Freezing can temporarily increase the temperature in the main chamber by 2–3°C. If there are perishable products (for example, milk or cheeses), it is better to move them to a cooler place while the mode is operating.

FAQ: Answers to frequently asked questions about Quick Freezing

Is it possible to enable Quick Freezing in a refrigerator with No Frost?

Yes, you can. The system No Frost does not conflict with Quick Freezing, but in such models freezing can take 10-15 minutes longer due to constant air circulation. The main thing is not to overload the freezer so that the cold is evenly distributed.

How long should Quick Freezing work?

The optimal time is 2-4 hours for a small amount of food (up to 2 kg) and 6-8 hours for a full load. In most refrigerators, the mode automatically turns off after 24 hours, but it is better to turn it off earlier so as not to waste extra energy.

Is it possible to freeze hot foods in Quick Freezing?

No! Hot foods (soup, roast, porridge) must first be cooled to room temperature, otherwise:

• The temperature in the freezer will rise, which will spoil already frozen foods.
• Condensation will form on the walls, which will then turn into ice.
• The time will increase frosts, and the mode may not work effectively.

The exception is models with the function Hot Freeze (for example, y Miele), but they are rare.

Why do products become covered with frost after Quick Freezing?

This happens due to:

• Unsealed packaging (air gets inside and condenses).
• Frequent opening of the door during operation.
• Overloading of the freezer (cold does not circulate, moisture settles on the products).

Solution: use vacuum bags or cling film, and do not open the freezer unless necessary.

Is there Quick Freezing in two-chamber refrigerators without a display?

Yes, but it may be hidden under another button. Look for:

• Button with a snowflake and lightning (❄️⚡).
• Inscriptions Super, Turbo or Fast.
• Lever or switch with position Max.

In older models (before 2010), this function may not exist at all - instead, manual temperature adjustment to maximum is used.
