Cold chain logistics development:
With the rapid development of my country’s society and economy, the people’s material living standards have been continuously improved, and the fast-moving consumer goods market has been continuously expanding.
Thanks to the increasingly developed transportation network and the development of refrigerated & refrigerated vehicle technology, various types of modern cold chain logistics systems have been widely used in the commercial transportation industry.
With the increasing demand and market, people have higher and higher requirements for food quality, and the cold chain logistics operations for various aquatic products, agricultural melons and fruits, quick-frozen food, packaged cooked food, dairy products and other foods are also increasing. Having attention.
Cold chain logistics development
Current status of cold chain logistics:
Cold chain logistics has rapidly expanded into a large-scale industry with strong equipment expertise, a wide range of industries, and a large number of employees. However, many urgent problems have also emerged in terms of standardized operation, operating efficiency, and industry management.
On the other hand, my country still lacks effective food and drug cold chain logistics management methods at this stage, and the lagging of the original monitoring technology is the biggest technical bottleneck. Manual measurement and paper records, no unified data system support, poor real-time performance, disconnected supervision; difficulty in obtaining evidence, unable to determine responsibility; unable to provide early warning, high loss rate, etc.
The status quo of cold chain logistics
