The question of what the ice cream refrigerator is called often confuses inexperienced entrepreneurs and simply inquisitive people. In everyday life, this equipment is often referred to simply as a “freezer”, but in the professional environment there is a clear gradation and specific terminology. Not only the understanding between the seller and the buyer, but also the choice of equipment with the required technical characteristics depends on the correct name.
The main difference between such a unit and a household refrigerator is the range of operating temperatures and the method of storing the product. If a standard refrigerator supports positive values for cooling, then low-temperature equipment it is obligatory to guarantee deep freezing. That is why it is most correct to call a specialized refrigerator for storing ice cream low-temperature freezer chest or display case, depending on the design and purpose.
In this article we will analyze in detail what types of equipment exist, than they differ and what nuances you should pay attention to when choosing. Understanding the difference between static cooling and the No Frost system will help you avoid damage to expensive products and save on electricity.
Basic terminology and classification of equipment
The first thing you need to understand: there is no single name “ice cream refrigerator” in a professional catalog. It all depends on how exactly the sale or storage will take place. If the product is in a deep container and is scooped up with a spoon, this is one type of equipment. If the ice cream is packaged in cups and stands vertically, it’s completely different.
The main classification criterion is the temperature regime. High-quality storage of ice cream requires a temperature no higher -18°C, and for some types of sorbet or soft ice cream the requirements may be even stricter. Equipment capable of maintaining such values belongs to the low-temperature class.
- ❄️ Chest freezer —a horizontal top-loading unit, ideal for storing large supplies in packaging.
- 🍦 Freezer display case —equipment with a transparent lid or an open type, intended for display and sale of goods.
- 🏪 Freezer cabinet is a vertical solution with doors used for warehouse storage or sale of packaged products.
It is important to distinguish between the concepts of “refrigeration” and “freezer”. The first operates in the range from 0 to +10 degrees, the second - from -18 and below. An attempt to store ice cream in a regular refrigerator will cause it to melt and lose its presentation within a few hours.
Chest freezers: design and purpose
When they talk about a classic “box” for ice cream, most often they mean a chest freezer. This is a horizontal chamber, the contents of which are accessed from above through a hinged or sliding lid. This design is not accidental: cold air is heavier than warm air, so when you open the top cover it does not evaporate, but remains inside.
Inside the chest there are often baskets or trays that allow you to structure the space. Static cooling system, which is most often found in such models, involves the formation of a layer of frost on the walls and product. This requires periodic defrosting, but it guarantees the absence of chapping of the product, since there is no active airflow.
Modern models can be equipped with heated double-glazed windows to prevent condensation from forming on the lid, obstructing the view. There are also chest freezers with curved glass that serve as a showcase, attracting the attention of buyers.
⚠️ Attention: Do not try to use a household chest freezer for commercial sale in a high-traffic area. Frequently opening the lid will lead to rapid heating of the product, since household insulation and compressor power are not designed for such loads.
Freezer display cases for cafes and shops
If your goal is not just storage, but a beautiful display to attract customers, you need a freezer display case. This is a more complex unit that combines the functions of a refrigerator and an advertising tool. Unlike solid chests, display cases have transparent walls and are often equipped with internal lighting.
There are two main types of display cases:
- 🔍 Closed display cases - have a glass lid that keeps the cold, but allows you to see the goods.
- 🌬️ Open display cases - do not have a door, cold held by an air curtain. Such models are often found in supermarkets.
Special display cases for soft ice cream or ice cream by weight. They are equipped with special gastronorm containers into which the product is loaded, and have a more precise temperature control system so that the mass does not crystallize and remains plastic.
When choosing a showcase, it is critical to pay attention to the exposure area and viewing angle. The buyer should see the product immediately, without having to look at an awkward angle. Energy efficiency of such models is also a key parameter, since they work 24/7.
Vertical freezers
Vertical equipment, or Freezers take up less floor space but require more height space. They resemble regular refrigerators, but with a more powerful freezer. Such units are often used for storing ice cream in cups, popsicles and briquettes.
Inside the cabinet, the product is protected from outside influences by a door. This can be a solid metal door (for a warehouse) or a glass display case (for a sales area). The advantage of vertical loading is the convenience of sorting: each type of ice cream stands on its own shelf, and there is no need to dig into the depths of the box.
| Equipment type | Temperature conditions | Loading type | Main application |
|---|---|---|---|
| Freezer chest | up to -24°C | Upper | Inventory storage, wholesale |
| Closed display case | -18...-22°C | Top/Side | Retail sales |
| Freezer cabinet | up to -20°C | Front | Packaged goods |
| Open display case | -18...-20°C | Open | Supermarkets (high traffic) |
It is worth noting that vertical cabinets with the system No Frost require special attention to product packaging. Constant circulation of dry air can quickly dry out unpackaged ice cream, making it tasteless.
Cooling systems: static versus No Frost
The choice between a static cooling system and No Frost (automatic defrosting) is an eternal debate among business owners. In the context of ice cream storage, each option has its fans and critics. Understanding the physics of the processes will help you make the right decision.
Static cooling (Direct Cool) works on the principle of natural convection. Cold air goes down, warm air rises. A “snow coat” forms on the back wall.
Advantages:
- The product does not weather.
- Less noise during operation.
- Cheaper to purchase and repair.
No Frost system implies the presence of a fan that drives air through the evaporator. Moisture is removed and frost does not form anywhere except the hidden block.
Advantages:
- No need to defrost manually.
- The temperature is the same at all points of the chamber.
- Restores cold faster after opening doors.
The myth of ice combustion
Many people believe that in No Frost the ice “burns”. In fact, it melts thanks to a heating element (heating element), which is turned on by a timer, and the water flows into the drain pan, where it evaporates.
For packaged ice cream (popsicles, cups), the No Frost system is often preferable due to ease of use. However, for loose ice cream or products sensitive to dryness, static is better suited.
Selection criteria and technical nuances
When purchasing equipment, it is not enough just to know what it is called. It is necessary to take into account a number of technical parameters that directly affect the service life of the equipment and the safety of the product. Ignoring these factors can lead to losses.
First of all, pay attention to the energy consumption class. Equipment running 24 hours a day can consume significant amounts of electricity. Models of the class A+ or A++ will pay for themselves in a couple of years due to savings on bills.
- 🔌 Compressor power - must correspond to the volume of the chamber. A weak compressor will wear out.
- 🌡️ Climate class —important if the display case is located in an unconditioned room or on the street (SN-T class).
- 🔊 Noise level —critical for small cafes, where the refrigerator is located next to the guests' tables.
⚠️ Attention: Check with the supplier for the type of refrigerant. Modern environmentally friendly gases (for example, R600a or R290) are safer for nature, but require more qualified service during repairs.
☑️ Check before purchase
Operating rules and common errors
Even the most expensive ice cream refrigerator will fail prematurely if the operating rules are violated. Often breakdowns occur not due to defects, but due to improper handling.
Never load warm products into the chamber. This causes a sharp jump in the load on the compressor and the formation of a large amount of condensate, which turns into an ice crust. It is also prohibited to seal ventilation holes or move equipment close to the wall - a gap of at least 10 cm is required to remove heat.
Regular washing and disinfection are required. Even if it is visually clean, bacteria can grow inside. Use only special products that do not damage plastic and rubber seals.
Frequently asked questions (FAQ)
Is it possible to store ice cream in a regular household refrigerator?
Only in the freezer if it is capable of maintaining a temperature of -18°C. In the main compartment (+4...+6°C) the ice cream will melt and lose its structure. However, household freezers are not designed for frequent opening, which is typical for retail.
How often do you need to defrost a chest freezer?
If you have a model with static cooling, defrosting is carried out as ice builds up (usually a layer of 3-5 mm), but at least once every six months. Models with No Frost do not need defrosting.
Why did the ice cream in the display case begin to crumble?
Most likely, the temperature regime was disturbed (the product thawed and froze again) or the air in the display case was too dry (No Frost problem without proper packaging). This may also be a sign of an expired shelf life.
What to do if the refrigerator makes a loud hum?
Check whether the unit is level (adjust the legs). If the compressor is humming, this may be a sign of wear or refrigerant problems. In this case, you need to call a specialist.
What temperature is ideal for storing soft ice cream?
For soft serve ice cream, the temperature in the dispenser is usually kept around -5...-7°C to preserve plasticity. To store replaceable cylinders (flaunces), standard freezing of -18°C and below is required.
