What is a commercial freezer?

Commercial freezer refers to the refrigerated or frozen freezer specially used for storing ice cream, beverages, dairy products, quick-frozen food and food raw materials in supermarkets, cold drinks shops, frozen goods shops, hotels and restaurants and other commercial channels. Commercial freezers are very professional, which requires not only professional storage temperature, but also powerful display. A well-displayed refrigerator can effectively promote the sales of operators. Therefore, a typical feature of commercial freezers is the use of single-layer or multi-layer transparent glass doors (except the kitchen refrigerator for storing ingredients), so that consumers can see the internal items without opening the refrigerator door.

There are obvious differences in channels and products between commercial freezer market and household freezer market in China. The commercial freezer market is mainly composed of large customer market and scattered customer market. Among them, freezer manufacturers mainly cover the industrial customer market in the form of enterprise direct sales, and determine the purchasing intention of commercial freezers through the bidding of major customers in the beverage and ice cream industries every year, but mainly rely on dealers to cover the scattered customer market.

Development history

Commercial freezer is the product of market economy. With the development of major beverage, ice cream and quick-frozen food production enterprises, the market scale is constantly expanding and the product forms are gradually subdivided. At first, incubators were generally used in the market to keep the temperature of articles. Later, with the appearance of freezers, ordinary foamed door freezers were used to store drinks and ice products for sale in supermarkets and street stalls. The rapid development of fast-moving consumer goods has led to the development and listing of commercial refrigerators. Due to more intuitive display, more professional storage temperature and more convenient use, the market scale of commercial refrigerators has expanded rapidly.

user group

Convenience store owners, cold drink shop vendors, supermarket salesmen, Internet cafe operators, hotel kitchens, cinemas, etc.

principle of operation

Commercial freezers use the same principle as ordinary freezers. They all use compressors to compress liquid refrigerants into high-temperature and high-pressure gaseous refrigerants, and then send them to the condenser to dissipate heat, which becomes low-temperature and high-pressure liquid refrigerants, so the condenser blows out hot air. Then it goes to a throttling device (generally a capillary tube) for throttling and depressurization, and then enters the evaporator. Because the space of the refrigerant suddenly increases and the pressure decreases after it reaches the evaporator from the capillary, the liquid refrigerant will vaporize and become a gaseous low-temperature refrigerant, thus absorbing a lot of heat, and the evaporator will become cold, and the temperature in the cabinet will be reduced by direct refrigeration or air cooling.

Notes for editing this paragraph

1. Household refrigerators use AC 220V/50Hz power supply. If the power supply conditions do not meet the requirements of AC 220V/50Hz (187-242V), an automatic voltage regulator above 1000W must be installed for use.

2. Independent special sockets must be used and grounded reliably. The refrigerator power cord is equipped with a (grounding) plug and a standard three-wire (grounding) socket. Under no circumstances should the third pin (ground) of the power cord be cut off or removed.

3. It is forbidden to store inflammable and explosive dangerous goods and strong corrosive acid and alkali in the freezer.

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

5. When combustible gas such as gas leaks; Close the gas leakage valve; Open the exhaust device and doors and windows; Do not plug in the power plug of the freezer;

6. Keep the key properly and don't let the children play in the cupboard to prevent accidents.

7. Once the power supply of the freezer is cut off, it will take more than five minutes to reconnect, so as not to damage the compressor or system. When maintaining, you must unplug the power plug. After the freezer is installed in place, the plug should be within reach to prevent the power plug from being pulled out in time in case of danger.

8. If it is necessary to extend the power cord, the cross-sectional area of the extension cord shall not be less than 0.75mm2 If the power cord is damaged, a special cord must be used and the after-sales service personnel of the local freezer company should be contacted to replace it.

9. Don't put food in the newly opened refrigerator. Let the empty freezer run for a period of time (about 3 hours in summer and 2 hours in winter), and then put the frozen food into the freezer for storage.

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

1 1. Clean the freezer regularly and unplug the power supply before safe cleaning. Regular dust removal of engine room heat exchanger can improve heat exchange efficiency and reduce energy consumption.

12. Commercial freezers with mechanical defrosting should be defrosted regularly, and the energy consumption of freezers should not be increased because the frost layer is too thick. When defrosting, first transfer the contents of the cabinet, let it stand for a period of time until the frost layer melts, and then use the defrosting shovel equipped with the freezer to remove it. Avoid using sharp objects to defrost strongly, so as not to damage the inner wall of the freezer.

product classification

Commercial freezers are generally divided into three categories: commercial freezers (also known as beverage freezers), commercial freezers (also known as cold food freezers) and kitchen refrigerators, with volumes ranging from 20L to 1600L. Among them, the temperature in the commercial refrigerator is 0- 10 degrees, which is widely used in the storage and sale of various beverages, dairy products, fruits, flowers and so on. According to the door opening mode, it can be divided into vertical (front door), top door and air curtain type. Vertical freezers can be divided into single doors, double doors, three doors and multiple doors. The top opening is barrel-shaped and square, and the air curtain type includes a front opening and a top opening. At present, the China market is dominated by vertical commercial refrigerators, accounting for more than 90% of the total market capacity. Haier's product line of commercial cabinets includes all kinds of freezers of this kind: desktop cabinets specially used for counter sales, single doors for supermarkets with smaller stores, double doors and three doors for medium and large supermarkets, and four-sided bar cabinets welcomed by chain convenience stores.

The temperature in the commercial freezer is generally below-15 degrees, which is mainly used for the storage and sale of ice cream, quick-frozen dumplings, glutinous rice balls and frozen meat. According to the structure and usage habits of the industry, it is divided into horizontal ice cream cabinets, island-style quick-frozen food cabinets, vertical commercial freezers, desktop cabinets and game cabinets. Horizontal ice cream cabinets are the mainstream of commercial freezers in China market, with common sizes ranging from 100L to 600L. The main models are Haier SD-332, SD-368, SD-5 18, etc. Island-style quick-frozen food cabinet, referred to as island cabinet, is a favorite product type of quick-frozen food customers and aquatic operators. Vertical commercial freezer is mainly used for the storage and sale of high-end ice cream because of its larger display area and more intuitive display effect. Haier SD-338, as the first manufacturer of air-cooled vertical freezers in China, has been leading the trend of vertical commercial freezers in China. Desktop cabinets are generally used for counter sales in high-end places, with small size and lovely appearance. SD-95 is a typical example of this kind of freezer.

Kitchen refrigerator, also known as kitchen freezer, is a low-temperature storage equipment used to store ingredients in the catering industry. Because the kitchen refrigerator is used in the back kitchen, it is in contact with food and raw materials, and has the characteristics of wear resistance, acid and alkali resistance, fire prevention, bacteria prevention and hygiene, so the kitchen refrigerator is generally stainless steel. Kitchen refrigerators are generally divided into desktop, two doors, four doors and six doors. From the point of view of structure and door body, the increase of kitchen refrigerator doors means that the number of spaces dividing different temperature ranges increases, which makes the function of kitchen refrigerator more perfect. Articles with different storage temperature requirements can be stored in different doors, which can reduce the mutual interference of stored articles and reduce the leakage of cold air. As a rookie in the industry, Haier kitchen refrigerator has entered the military supply channel with Haier's strong technical reserves, advanced experimental testing equipment and professional production technology.
