Cold Chain Logistics

China's logistics development presents three major characteristics: accelerated development speed, accelerated enterprise growth and intensified market competition. The intensification of market competition leads to the acceleration of professional division of labor, the specialization of demand leads to the segmentation of a market, and more professional logistics enterprises such as automobile logistics, pharmaceutical logistics, tobacco logistics, grain logistics, cold chain logistics and so on have emerged. Due to the rise of chain distribution system, the change of food circulation form, the refinement of professional division of labor and the gradual popularization and maturity of low-temperature food, cold chain logistics has suddenly heated up and become the focus of people's attention.

Cold chain logistics generally refers to a systematic project in which refrigerated and frozen foods are always in a prescribed low temperature environment in all aspects of production, storage, transportation, sales, and consumption to ensure food quality and reduce food loss. It is established with the progress of science and technology and the development of refrigeration technology. It is a low-temperature logistics process based on refrigeration technology and using refrigeration technology as a means.

Cold chain logistics includes: primary agricultural products: vegetables and fruits; Meat, poultry and eggs; Aquatic products and flower products. Processed food: frozen food, poultry, meat, aquatic products and other packaged cooked food, ice cream and dairy products; fast food raw materials. Special commodities: drugs. Since the food cold chain is a supply chain system that aims to ensure the quality of perishable food and maintains a low-temperature environment as the core requirement, it has higher and more complex requirements than general room temperature logistics systems, and the construction investment is much larger. A huge system engineering. Since the timeliness of perishable food requires higher organizational coordination of all links in the cold chain, the operation of the food cold chain is always related to energy consumption costs, and effective control of operating costs is closely related to the development of the food cold chain.
