Biological products cold chain logistics, involving the storage, transportation and other related links of biological products, biological products cold chain logistics generally use physical cold chain methods. Compared with the normal temperature logistics system, the cold chain logistics of biological products has higher requirements and is more complex, mainly with the following characteristics:
1. High cost.
In order to keep biological products at the specified low temperature conditions throughout the distribution, it is necessary to use refrigerated trucks or cryogenic warehouses equipped with temperature control equipment. In order to improve the operational efficiency of biological products cold chain logistics, it is necessary to adopt advanced information systems, which determine that the investment cost of biological products cold chain logistics is much larger than that of room temperature logistics.
2. Timeliness.
Biological products have a certain expiration date and their quality is susceptible to temperature changes. In order to achieve a high level of service, there is often a time window when the goods arrive at the sales end, so the biological product cold chain logistics must deliver the products within the agreed time limit.
3. High coordination.
The cold chain logistics of biological products is a complex system engineering, which integrates refrigeration, logistics and information technology, and requires a high degree of cooperation and coordination between all links of the cold chain.
4. Complexity.
The quality of biological products changes with temperature and time in the circulation process, and different products must have corresponding temperature and storage time. At the same time, the whole process of cold chain logistics of biological products requires complex technical support such as refrigeration technology, thermal insulation technology, temperature control and monitoring, which increases the complexity of cold chain logistics of biological products.
