It is established with the progress of science and technology and the development of refrigeration technology, and it is a low-temperature logistics process based on refrigeration technology. With the rapid development of cold chain logistics of agricultural products in China, the state must formulate and implement scientific and effective macro policies as soon as possible. The requirements of cold chain logistics are relatively high, and the corresponding management and capital investment are also greater than ordinary normal temperature logistics.
The application scope of cold chain logistics includes: primary agricultural products: vegetables and fruits; Meat, poultry and eggs; Aquatic products, flower products. Processed food: frozen food, packaged cooked food such as poultry, meat and aquatic products, ice cream, dairy products and chocolate; Fast food ingredients. Special commodity: medicine, so it is a huge system engineering with higher requirements, more complexity and much larger construction investment than the general normal temperature logistics system. Due to the timeliness of perishable food, all aspects of the cold chain need high organization and coordination, so the operation of food cold chain is always related to energy consumption cost, and effective control of operation cost is closely related to the development of food cold chain.
