is due to the joint completion of manufacturers, wholesalers and retailers. In the early days, low-temperature walk-in cooler sales included wholesale and retail of frozen food. The sales of frozen food are mainly borne by retail vehicles and retail stores of retailers. In recent years, the emergence of a large number of supermarkets in cities has made it the main sales channel for frozen food. The walk-in cooler in the supermarket has the functions of cold storage and sales. To choose a low-temperature walk-in cooler that suits you, we need to understand all kinds of knowledge about low-temperature walk-in cooler.

　　 Under the conditions of a market economy, the commercial system, the light industry system, the foreign trade system, and the aquatic product system all produce frozen food in their own way. There is no uniform industry standard and norm to follow. How can management be disorderly, resulting in uneven quality of frozen food , The quality is uneven. As for the current situation, there are problems with frozen food: In addition, most frozen food manufacturers in the country use the original cold storage, low-temperature walk-in cooler, etc. to produce frozen food, without continuous rapid freezing equipment, and no unified product. Quality standards and hygienic regulations have caused slow frozen products to flood the market, reducing the quality of frozen foods and damaging the reputation of frozen foods.

　　 Food refrigeration is composed of four aspects: frozen processing, frozen storage, refrigerated transportation and frozen sales: including the cooling and freezing of meat and fish; the pre-cooling of fruits and vegetables and the processing of various quick-frozen foods. Mainly involves cooling and freezing devices. It also includes the modified atmosphere storage of fruits and vegetables. It mainly involves various types of cold storage, refrigerated walk-in cooler, frozen walk-in cooler and household walk-in cooler, etc. Frozen storage: including refrigeration and freezing of food. Therefore, refrigerated transportation: includes medium and long-distance transportation and short-distance delivery of food. It mainly involves low-temperature walk-in cooler transportation vehicles such as railway refrigerated trucks, refrigerated cars, refrigerated ships, and refrigerated containers. The fluctuation of temperature during transportation is one of the main reasons for the deterioration of food quality. Transportation tools must have good performance, not only to maintain the specified low-temperature walk-in cooler, but also to avoid large temperature fluctuations, especially for long-distance transportation.

　　 chose a low-temperature walk-in cooler that suits you. Its maintenance and maintenance are particularly important for prolonging its life and normal use. Inaccurate temperature control often leads to damage to the stored objects, which greatly affects the results of the experiment. The research work is proceeding normally. In the event of a power failure, the power switch and battery switch behind the walk-in cooler must be turned off. When the normal power supply is restored, the power switch behind the walk-in cooler must be turned on before turning on the battery switch. Note that heat dissipation is very important to walk-in cooler. Keep indoor ventilation and a good heat dissipation environment. The ambient temperature cannot exceed 30C.
