The raw materials used in deli display case are generally tempered glass. The use of display cabinet materials makes the product more resistant to corrosion, and it can be easily cleaned. The product is very convenient to use. In addition, the display cabinets are all glass on all sides, and the airtight design not only has a good display effect, is safe and beautiful, but the fully enclosed design makes the cabinet cooler and can save energy.



The food placed inside the cabinet also needs to leave a gap to facilitate the circulation of cold air. The place where the air vent of the cabinet should not be filled with food. In addition, the cabinet will be defrosted and defrosted in the refrigerating cabinet, and the thicker frost on the surface of the evaporator can be removed with ice shovel. Avoid shoveling scratches on the surface of the evaporator when defrosting. It is recommended that you do not use sharp tools to shovel the frost. After the defrosting is over, the refrigerator and freezer compartments in the cabinet can be scrubbed with dry rags, and the water drops in the cabinet can be wiped off to prevent the cabinet from working again and re-frosting and freezing.



Shopping malls need to pay attention to certain use skills when using deli display case. If it is the first use, you can plug in the power and let it work for a period of time before putting food in the display cabinet. If the noise is too loud during work, try to eliminate the fault. , If you can’t find the reason, you can find a professional maintenance person for on-site service. In addition, you need to pay attention to prevent the amount of cooked food, and there should be no too much food in the display cabinet, otherwise it will affect the air flow of the cabinet and affect the cooling effect.



The deli display case has many functions, the most important of which is the coexistence of preservation and display. When using the display cabinet, it is best to read the instructions in advance to reduce machine damage caused by operating errors.

In this article, we will provide a guide on what to consider before choosing the best glass door to showcase your refrigerator.



Displaying refrigerators is one of the most important necessities of the food business. Displaying products in the best way is the best way to attract customers. Display cabinets are specially designed to display food or any other product in a pleasant way. These display units are also called glass door display refrigerators. These wine beverage fridges are widely used in cafeterias, restaurants, bakeries and shops.



When choosing a supermarket display refrigerator, you need to consider some of the following.



Get a second-hand refrigerator or a new one?

Buying a second-hand refrigerator will definitely save some money, but there are a few things to consider before buying a second-hand refrigerator. It is important to check the compressor of the equipment, because all the heavy work needs to be done by the compressor. If the compressor is damaged, the compressor needs to be replaced, which will cost more than buying a new refrigerator. Therefore, it is best to buy new equipment, as new equipment comes with warranty and maintenance services, albeit much more expensive than using older equipment.Another advantage is that the new refrigerator is more energy efficient.



Choice of ideal capacity:

These glass door display refrigerators are sized in cubic meters, and capacity requirements vary based on the type of product you plan to display. Before choosing a refrigerator, you need to be very clear about how much food you need to store at one time, because too much inventory can affect the efficiency of your equipment.



If the capacity is larger than the device requires, it will eventually look as if you have run out of product; if the capacity is less than the required capacity, you will end up with excess inventory. Neither case will leave a good impression on the customer.



Know the exact size:

There are many display refrigerators in different designs on the market, before you start looking for a supermarket display refrigerator that fits your location. The first thing to do is to measure the size of the space available on the device, and the width and height of that place should be measured correctly. Second, the type of door needs to be considered, because if the display refrigerator is an upright display refrigerator and has a hinged door, it will require more space to open. If the device has a sliding door, you can save even more space. Both external and internal dimensions should be considered because two units with the same external dimensions may have different capacities depending on their internal dimensions.

First, high-quality glass door upright cooler are made of high-quality copper coils, processed into spacious and diverse shapes.

　　The surface finish of the stainless steel plate is good, and the overall thickness of the plate is uniform. Because it guarantees a long life with uniform thickness, the overall appearance of the glass door upright cooler looks flat and strong. At the same time, copper pipes have better refrigeration effects than aluminum pipes and composite pipes, and have better corrosion resistance. There are few cleanliness and pipe connections in the excellent copper coils, which effectively prevent leakage and blockage in the refrigeration system. The round tube is processed into a rectangle, and the contact between the evaporator tube and the refrigeration liner increases from point contact to surface contact, which expands the cold transfer area and improves the cooling speed of the high-quality glass door freezer compartment.

　Second, the thermal insulation effect of high-quality glass door upright cooler is very important.

　　 The thermal insulation of the glass door upright cooler is an important index to measure the quality of the glass door upright cooler. When manufacturing the glass door upright cooler, it is necessary to use the material temperature control and special fixtures and master the first-class foaming technology to ensure the excellent heat preservation performance of the glass door vertical cooler.

   Third, the overall structure of the glass door upright cooler is stronger.

　　 The sturdiness of a glass door upright cooler has a lot to do with the life of the glass door upright cooler. An integrated angle steel frame is used between the outer shell and the inner container of the high-quality glass door upright cooler, which is like the steel bars on the concrete prefabricated panel, which somewhat improves the robustness of the high-quality glass door upright cooler. After welding the door frame of the glass door upright cooler, one-time foaming is performed, which can avoid the shortcoming that the glass door upright cooler door is easy to fall off.

Commercial supermarket display fridges refer to freezer or cooler that are exclusively used for the storage, display of ice cream, beverages, dairy products, quick-frozen foods, and food materials in commercial business channels such as supermarkets, cold drink shops, frozen stores, and hotel restaurants etc. Commercial refrigerators have a strong professionalism, not only have professional storage temperature requirements, but also strong requirements for display. Good display refrigerators can effectively promote sales, so a typical feature of commercial refrigerators is with single-layer or multi-layer transparent glass doors, consumers can see the contents without opening the door.

Precautions

1. Domestic refrigerators use AC 220V / 50Hz power supply. If the power supply conditions do not meet the AC 220V / 50Hz (187-242V), you must install an automatic voltage regulator with more than 1000W for use.

2. Must use independent dedicated socket and reliable grounding. The power cord of the freezer is equipped with a (grounded) plug that conforms to a standard three-wire (grounded) outlet. In any situation,do not cut or remove the third pin of the power cord.

3. It is strictly prohibited to put flammable and explosive dangerous goods and strong corrosive acids and alkalis in the freezer.

  4. Do not use flammable spray near the freezer to avoid fire.

  5. When there is leakage of flammable gas: close the gas leakage valve; open the exhaust device and doors and windows; do not unplug the power plug of the refrigerator;

   6. Keep the keys in a safe place. Do not let children play in the cabinet to prevent accidents.

   7. Once the freezer is disconnected from the power supply, wait five minutes or more before turning it on again to avoid damage to the compressor or the system. During maintenance, the power plug must be unplugged. After the freezer is in place, the plug should be accessible to prevent unplugging the power plug in time if a danger occurs.

  8. If the power cord needs to be extended, the cross-sectional area of the extension cord must not be less than 0.75mm2. If the power cord is damaged,must use a dedicated cord and contact the freezer company's local after-sale service personnel to replace it.

  9. Do not put food in the freezer immediately after the power is turned on. Let the empty cabinet run for a period of time (about 3 hours in summer and about 2 hours in winter), and then store the frozen food in the cabinet.

  10. After the freezer is moved, leave it for more than ten minutes before turning on the power.

  11. Regularly clean the freezer, and unplug the power plug for safe. Regular dust removal of the heat exchanger in the engine room can improve heat exchange efficiency and reduce energy consumption.

  12. Mechanical defrosting commercial freezers should be defrosted regularly to prevent the thick frost layer increasing the energy consumption. When defrosting, first transfer the goods, leave it for a while to melt the frost layer, and then use a defrost shovel to remove it. Don’t use sharp things to defrost for protect the inner wall.
