What is cold chain logistics? In recent years, the rapid development of cold chain logistics in our country, cold chain logistics has gained popularity in our lives, but let us talk about cold chain logistics specifically, many people are not clear . So what exactly is cold chain logistics? In fact, cold chain logistics means that refrigerated and frozen foods are in a specified low temperature environment during the production, storage, transportation, and sales, to pre-consumption, to ensure food quality and reduce food loss A system engineering of.

   In general, cold chain logistics has 4 major links: The first is the freezing processing link of cold chain logistics. This link includes the cooling and freezing of meat and poultry, fish and eggs, as well as the processing operations at low temperatures, as well as the pre-cooling of fruits and vegetables, and the low-temperature processing of various quick-frozen foods and dairy products. In this link, the cold chain equipment mainly involves cooling, freezing devices and quick freezing devices.

   The second link is the cold storage of cold chain logistics. This link includes the cooling storage and freezing storage of food, as well as the modified atmosphere storage of fruits and vegetables and other foods. It is to ensure the low-temperature preservation environment of food during storage and processing. This link mainly involves various types of refrigerators/processing rooms, refrigerators, freezers and household refrigerators.

   The third is the refrigerated transportation link of cold chain logistics. This link includes the low temperature conditions of the long-distance and mid-distance transportation and short-distance distribution of food. It mainly involves refrigerated vehicles, refrigerated trains, refrigerated ships, refrigerated containers and other low-temperature transportation vehicles. In the process of refrigerated transportation, temperature fluctuations caused by external influences are one of the main reasons for the deterioration of food quality. Therefore, transportation tools should have good performance. While maintaining the specified low temperature, it is necessary to maintain a stable temperature, especially for long-distance transportation. important.

   The last one is the frozen sales link. Frozen sales include the frozen storage and sales of various cold-chain foods entering the wholesale and retail links, which are jointly completed by manufacturers, wholesalers and retailers. With the rapid development of various chain supermarkets in large and medium-sized cities, various chain supermarkets are becoming the main sales channels for cold chain food. In these retail terminals, a large number of refrigeration, freezing display cabinets and storage warehouses are used, and they become complete food An indispensable and important link in the cold chain to create final profits.

Summarizing the four major links of cold chain logistics, it can be seen that these four links of cold chain logistics are all interlocking, and all need to be in the state of the entire low-temperature cold chain. If there is an error in one of the links, the cold chain logistics The entire cold chain is broken, and this will have a huge impact on the safety and health of our food and drugs. Therefore, cold chain logistics is related to our life safety and health, so I must strengthen the construction of cold chain logistics, improve the safety standards of cold chain logistics, and protect our life safety and health.
