Freezer display cabinets are available in vertical and horizontal styles. Consumers can choose different styles according to different needs. Generally in supermarkets, glass door freeze display cabinets are generally used to store meat, dumplings, dumplings, buns and other products that need to be frozen. This is not only convenient for consumers to choose and buy, but also to maintain the freshness of frozen products. The horizontal freezer is also used to store meat, dumplings, dumplings, dumplings and other products that need to be frozen. Because these consumer products are large and occupy a lot of volume, and more consumers buy these products, horizontal refrigerators are more convenient for consumers to choose.





In the daily use of glass door freezer display cabinet fridge, some problems need attention. Do not open the door of glass door freezer for a long time. Because the freezer is opened, a lot of hot air from the outside will run in, and the cold air in the freezer display will run out, which will form air convection, so that the products inside will not be able to keep freshness. The hot air entering the glass door freezer display case freezes when it is cold. Opening the door of the glass door freezing display cabinet for a long time, it is easy to build thick ice cubes in the refrigerator.





Things to note when using:


1. Clean the refrigerator before use


Before using the freezer, wipe the shelf and the cabinet clean, and do the cleaning work every day. The safety of the food industry is the first element. When using glass door freezer display cabinets, pay attention to cleaning up garbage. Don't pile up too much garbage in the glass door freezer display cabinet, and clean up the generated garbage in time.





2.Keep ingredients cold and sealed before putting them in the freezer


Allow food to cool to room temperature and cover it with a display tray or plastic wrap before placing it in the freezer. This not only avoids frost and humidity problems in glass door refrigerators, but also avoids contamination of food by customers accidentally touching it. Do not block the air vent when placing food, otherwise the cooling effect is not good.





3. The freezer must be operated at night


Commercial refrigerators are the same as domestic refrigerators. After the temperature reaches a certain range, the compressor will stop running; when the temperature rises, the compressor will automatically start cooling. During the operation of the store, do not close the freezer when the door is closed to save power. Not only does the food not be stored well, it also reduces the life of the freezer.





4. Be familiar with the operating instructions of the freezer


When the refrigerator freezes occasionally, it can be reset after the power is turned off for a period of time. Different foods have different temperature requirements, and different temperatures can be set for the refrigerator according to the type of food. Classified storage, professional health.





This is what APEX explained about the matters needing attention when using glass door freezer display cabinets. Do you know?

For supermarkets and convenience stores, the fog on the glass of supermarket display fridges can prevent customers from viewing their products and may reduce impulsive purchases.





Why does the glass door condense fog?


Compared with cold air, hotter air can hold more moisture. "Dew point" is the temperature at which the air cools to saturation when the water vapor content in the air is constant and the air pressure is kept constant. A glass of ice water will begin to sweat in a warm room because the air in contact with the glass is cooled to the dew point. The same thing happens when the colder surface of the glass door comes into contact with the hotter air in the building.





How to solve this problem?


Replace damaged components


A damaged door gasket may allow humid air to enter the walk-in room. This air will cool to the dew point and lose excess moisture, which will produce mist. If you have a heated door, the foggy door may indicate that you need to replace the heater wire. Some heated glass doors have anti-sweat controls and may not work properly.





Adjust thermostat


Try to raise the temperature in the walk-in cooler slightly, or raise the surface temperature of the door to a temperature that does not cause water to condense on the door. It can also be cooled by setting an air conditioner, which helps absorb more moisture from the air near the walk-in radiator. You can try using a dehumidifier to help remove excess moisture from the air.





Buy new glass door


If you are in the new glass door market, please consider buying models with heated glass or anti-fog coating. Under high humidity conditions, these coatings cause condensation to form a transparent layer instead of forming misty droplets. APEX provides a glass door model that does not sweat. Newer doors usually have better thermal insulation, which will result in a lower surface temperature and less condensate.

         The deli display case is a necessary refrigerated display equipment for the deli. Although it has the function of refrigerating and keeping fresh, it still cannot completely kill the bacteria. Therefore, the deli display case needs to be disinfected regularly, otherwise it may cause food safety problems.

        

        The refrigeration and freezing of deli display case are actually two concepts. Freezing refers to lowering the temperature to solidify and freeze objects, which is also called "refrigeration". Refrigeration is a method of preserving food under refrigeration temperature (usually above the freezing point) after cooling, especially for fruits and vegetables, mainly to delay their life metabolism process as much as possible and maintain their freshness.
       
        In the cooked food display cabinet, the best temperature for storing cooked food is about 2~8 degrees, because the reproduction speed of microorganisms in this environment will be inhibited to a certain extent, but some bacteria are more psychrophilic, just like yeah Ersenia, Listeria, etc. can grow and multiply rapidly at this temperature, so if you eat such infected food, it will cause intestinal diseases. The temperature of the freezer compartment in the deli display case is generally around minus 18°C. At this temperature, general bacteria can be inhibited or killed, so the food stored in it has a better preservation effect. But freezing does not mean that it can be completely sterilized, because there may be some bacteria with strong anti-freezing ability that will survive. In this case, we must disinfect, so as to ensure that consumers will not eat this kind of cooked food. Infected by bacteria.



        Because the low temperature of the deli display case can only inhibit the growth of bacteria and prolong the preservation time of the cooked food, in order to ensure the safety and sanitation of the food, the deli display case must regularly clean the internal cooked food residue and then disinfect it. In this way, food safety problems can be avoided to the greatest extent.

        The principle of ice cream display fridge refrigeration is to use cold air to blow out, so that the cold air can evenly cover every corner of the cabinet, so as to achieve the freezing effect of the product. The ice cream display fridge mainly stores ice cream food and displays the function of selling. The temperature is normally set between -16 and -18 degrees.



        Although the ice cream display fridge is similar to other ordinary refrigerators, the upper part of the display cabinet is made of glass, so it is more prominent, because this not only allows customers to clearly see the ice cream inside, and choose their favorite flavors, but also at the same time The ice cream can also be stored at low temperature to maintain the texture of the ice cream.



        Whether for ice cream shops or ice cream factories, ice cream display fridge is indispensable. But how to choose a high-quality and suitable ice cream display fridge? Three points are briefly described below.

        1. The machine itself

        When buying an ice cream display fridge, there are three factors that must be considered:

        Ice cream display fridge configuration: The machine configuration of ice cream display fridge (such as compressor, motor, condenser, etc.) must be able to ensure the durability of the machine.



        Ice cream display fridge storage environment: The environment where the display cabinet is placed is also very important. If the temperature of the environment where the store is located is high, then you should choose a high-temperature display cabinet.



        The internal temperature of the ice cream display fridge: The display cabinet is used to store the display ice cream, so its storage temperature is set between -16 and -18 degrees, and when choosing a display cabinet that meets the requirements, make sure it It can maintain the taste and shape of ice cream.

 

         2. Machine design (size, color, trademark, etc.)

         The ice cream display fridge must not only allow customers to clearly see the ice cream stored inside, but also see the beauty of the exterior. If it can be harmoniously matched with the surrounding food, it will be more attractive to customers, but this requires a design for the display cabinet. Requested. The size of the display cabinet depends on the area of ​​the store.

         

         Three, energy saving

         Because the ice cream display fridge needs to operate for a long time, energy saving has become one of the factors affecting the selection of display cabinets.

Electric glass defrosting function:

The electric glass defrosting function is designed to remove the frost layer formed on the glass surface due to low temperature, ensure the clear visibility of the glass, and provide users with good observation conditions. This function is essential for commercial refrigerators that need to clearly observe the internal items.

Working principle:

The defrosting of electric glass is based on the principle of resistance heating. In the interlayer of the glass, fine resistance wires are embedded or coated with conductive coatings. When current passes through these resistance elements, electrical energy is converted into thermal energy, and the glass heats up.

The frost layer melts into water after being heated, and then evaporates or is discharged along the drainage system of the refrigerator. Since the heat is evenly distributed inside the glass, the entire glass surface can be defrosted synchronously without the situation of local residual frost.

For example, in the resistance wire type electric heating glass, the resistance wire is distributed in a specific arrangement. When the current passes, the resistance wire heats up and the heat is quickly transferred to the glass surface.



Application introduction in commercial refrigerators:

Commercial refrigerators are usually used to store and display large quantities of refrigerated or frozen goods. In low temperature environments, the glass door of the freezer is prone to frost, which affects customers' observation and selection of goods.

Commercial freezers equipped with electric glass defrosting function can effectively solve this problem. Merchants do not need to frequently defrost manually, saving time and labor costs.

Customers can also clearly see the goods in the freezer, improving the shopping experience. Moreover, the continuous clear view helps merchants to better display goods and promote sales.

For example, in the frozen food area of ​​the supermarket, the freezer with electric glass defrosting function allows customers to see the packaging and labels of various frozen foods at a glance, which is convenient for purchase.

In the hotel's kitchen freezer, the chef can quickly and accurately find the required ingredients without having to wipe the frost layer laboriously.

In addition, the electric glass defrosting function also improves the energy efficiency of the freezer. Due to the reduction of the frost layer, the refrigeration system of the freezer does not need to consume more energy to overcome the insulation effect of the frost layer, thereby reducing operating costs.

In short, the application of electric glass defrosting function in commercial freezers not only improves the convenience and display effect of the freezer, but also brings the advantages of energy saving and reduced operating costs.
