The supermarket is currently the most popular retail place in the city. As a senior foodie, entering the supermarket is mainly to find food, and cooked food is also one of the foods that cannot be ignored. In order to preserve and display the cooked food, the supermarket will put the food in the deli display case. Here is an introduction to the functions and use skills of the display cabinet.



As the name suggests, the deli display case is a kind of cabinet that can display cooked food. The main function of the deli display case is to keep the food fresh and reduce the deterioration of the food due to the hot weather. As a tool, the deli cabinet is not only useful for displaying food, but also can attract customers to consume, drive the distance between customers and the shopping mall, increase customers' enthusiasm for buying cooked food, and bring economic benefits to businesses.



At present, the deli display cases on the market are divided into different types. Whether it is a normal temperature display cabinet, a refrigerated display cabinet or a heated display cabinet, the temperature of the cabinet can be reduced, thereby reducing the speed of bacteria movement in the cabinet, thereby Prolong the preservation time of food.

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.

1. The basic requirements for the refrigeration system of the commercial display freezer: compressor (heart): seal each nozzle before use, pull out the rubber plug when used; condenser: paste; filter drier: dry filtration, sealed before use, ready for use Unpacking; capillary tube: flow, pressure drop; evaporator: paste; pipeline: the pipeline does not touch, the inside of the tube is clean, and each welding point does not leak; comprehensive testing of refrigeration performance, electrical performance, and noise testing.

2. The basic requirements of the commercial display freezer thermal insulation system: the foaming quality of the commercial display freezer and door body: appearance, size, foam density, freezing test. Door seal: appearance, size, welding performance, suction and elastic compensation. Commercial display freezer and door seal assembly: there is no gap, the door seal has a certain width on the steel plate, and the door opens with a certain force.

3. The basic requirements of the commercial display freezer temperature control system: thermostat inspection, hot and cold temperature points, and consistency. Fixing of temperature sensing tube: positioning size, consistency. Lighting: Lights up when the door is opened, and goes off when the door is closed, durability.

        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.
