Supermarket Freezers

In recent years, thanks to the “lazy economy”, sales of frozen food in supermarkets have continued to grow rapidly. Sales of glass door merchandiser & island freezer , frozen foods have increased by 30% each year.

Fragrant finger cakes, chicken rice, shish kebabs and even churros. They only need to be heated for a few minutes and can be eaten at home. Frozen foods are becoming more and more popular among young people.

The combined chest frozen island freezer and glass door merchandiser in the supermarket are getting longer and longer, and the variety of food from the original dumplings and pastries to today’s steaks and kebabs is getting richer. It is reported that in recent years, frozen food has maintained a high sales growth rate, and young people are their main consumer groups.

Supermarket freezers are extremely important for the development of the frozen food industry. While manufacturers provide various cost-effective products to dealers, they also bring many solutions to the actual situation of each dealer, and they escort the development of dealers.

In particular, the safety of frozen food in island cabinets has received strong attention from food distributors.The island freezer is deeply refrigerated and adopts strict corporate standards to achieve the offline -18 ℃ freezing standard to inhibit the growth of bacteria. The unique antibacterial material and integrated cabinet mouth design prevent the invasion caused by outer bacteria to the safety of food; Environmental friendly materials, pollution-free; the use of imported brand compressors and fans to ensure the stable operation of core components. At the same time, the entire machine has undergone rigorous reliability tests for 1080 hours at high and low temperatures to ensure product reliability and service life. Then it fundamentally solves the many doubts of users, and truly gives users peace of mind and benefit.

Supermarket freezers refer to  glass door merchandiser & island freezer used in commercial places such as supermarkets, frozen warehouse, hotels and restaurants. Supermarket freezers have a strong professionalism. Do you know the principles and precautions of using commercial refrigerated showcases? Let me give you a detailed introduction.
Similar to the principle used by ordinary refrigerators, commercial refrigerated cases use a compressor to compress a liquid refrigerant into a high-temperature and high-pressure gaseous refrigerant; it is then sent to a condening unit, after cooling, it is be to a low-temperature and high-pressure liquid refrigerant. So the condenser is blowing hot air. Then it is sent to a throttling device (usually a capillary tube) to reduce the pressure and enter the evaporator. Due to the sudden increase in space after the refrigerant reaches the evaporator from the capillary tube, the pressure decreases, and the liquid refrigerant will vaporize and become a gaseous low temperature. The refrigerant will absorb a large amount of heat, and the evaporator will become cold at this time. Direct cooling or air cooling is used to cool the cabinet.

Supermarket freezers use high-efficiency brand compressors and energy-saving temperature control systems; they are equipped with wire tube evaporators. Due to direct contact with food, the freezing speed is extremely fast and energy consumption is greatly reduced. The use of IQ DC energy-saving fans, cold air circulation in the cabinet, the temperature throughout the refrigeraiton cabinet is uniform and stable, to achieve the purpose of reducing energy consumption and bring greater business profits for customers.
China Domestic refrigerators use AC 220V / 50Hz power. If the power supply condition does not meet the AC 220V / 50Hz (187-242V), the user must install an automatic voltage regulator of more than 1000W to cooperate with the use.

The user must use a separate dedicated socket with grounding line. The power cord of the cabinets is equipped with a (grounded) plug that conforms to a standard three-wire (grounded) outlet. Under no circumstances should the user cut or remove the third pin (ground) of the power cord.

It is strictly prohibited to put flammable, explosive dangerous goods and strong corrosive acids and alkalis in the commerical refrigeration freezer&Chiller. Do not use flammable sprays near refrigerators to prevent fire. When there is leakage of flammable gas such as gas, close the gas leakage valve, open the exhaust device, doors and windows, and do not pull or insert the power plug of the refrigerator. Keep the keys in a safe place. Do not let children play in the cabinet to prevent accidents.

Once the freezer is disconnected from the power supply, we need to wait for more than five minutes before reconnecting it to avoid damage to the compressor or the system. During maintenance, the power plug must be unplugged.

After the refrigerated cabinet is in place, the plug should be accessible so that we can remove the plug in time if any danger occurs. If the power cord needs to be lengthened, the cross-sectional area of the extension cord must not be less than 0.75 square millimeters.
If the power cord is damaged, it must be repaired with a dedicated cord, and contact the local after-sales service of the refrigerator company to replace it. Do not put food in the freezer just after the power is turned on. After the empty cabinet has been running for a period of time (about 3 hours in summer and about 2 hours in winter), store food into the cabinet for frozen. After moving the refrigerator, leave it for more than ten minutes before turning on the power. Clean the refrigerator regularly. Regular dust removal of the heat exchanger in the engine room can improve heat exchange efficiency and reduce energy consumption. Commercial fridges should be defrosted regularly to avoid the thick layer of frost increasing the energy consumption. When defrosting, first transfer the goods in the cabinet, leave it to stand for a period of time until the frost layer melts, and then use a defrost shovel equipped with the refrigerator to avoid defrosting with sharp objects to avoid damaging the interior wall of the refrigerator.

The above is the principle and precautions for commercial fridges. Although commercial fridges is not used at home, it is very useful for businesses. Pay attention to some details when purchasing and using a commercial fridges. I hope the above content can help everyone.
