Because manufacturers, wholesalers and retailers are done together. In the early days, low-temperature
freezer sales included wholesale and retail of frozen food. The sales of frozen food are mainly undertaken by retailers' retail carts and retail stores. In recent years, the proliferation of supermarkets in cities has made it the main sales channel for frozen food. The freezer in the supermarket has both the functions of refrigeration and sales. To choose a low-temperature freezer that suits you, we need to understand all kinds of knowledge about low-temperature freezers.
Under the conditions of the market economy, the commercial system, the light industry system, the foreign trade system, and the aquatic product system all produce frozen food independently. There is no unified industry standard and specification to follow. How can the management be in a disordered state, so that the quality of frozen food is uneven Uneven quality In 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 freezer, etc. to produce frozen food, there is no continuous rapid freezing equipment, and there is no unified product quality standard and hygiene. Regulations, resulting in slow freeze production flooding the market, reducing the quality of frozen food, and damaging the reputation of frozen food.
Food refrigeration consists 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, etc. Mainly related to cooling and freezing devices. It also includes modified atmosphere storage of fruits and vegetables. Mainly involves various types of refrigerators, refrigerated freezers, frozen freezers and household freezers and so on. Frozen storage: including refrigeration and freezing of food. Therefore, refrigerated transportation: including medium and long-distance transportation and short-distance delivery of food. It mainly involves railway refrigerated trucks, refrigerated vehicles, refrigerated ships, refrigerated containers and other low-temperature freezer transport vehicles. The fluctuation of temperature during transportation is one of the main reasons for the deterioration of food quality. The means of transport must have good performance, not only to maintain the specified low temperature freezer, but also to avoid large temperature fluctuations, especially for long-distance transportation.
Choose a low-temperature freezer that suits you. Its maintenance and maintenance are particularly important for prolonging its life and normal use. If the temperature control is not accurate, the stored objects are often damaged, which will have a great impact on the experimental results and thus affect the normal research work. conduct. When a power failure occurs, the power switch and battery switch behind the freezer must be turned off. When the normal power supply is restored, first turn on the power switch behind the freezer, and then turn on the battery switch. Note that heat dissipation is very important to the freezer. To maintain indoor ventilation and a good heat dissipation environment, the ambient temperature should not exceed 30℃.
