1, temperature control and insulation

Constant temperature cold storage: a cold storage with precise requirements on the temperature and humidity of stored items, including constant temperature and humidity cold storage. Controlled atmosphere refrigeration: It can not only adjust the temperature and humidity in the warehouse, but also control the contents of oxygen, carbon dioxide and other gases in the warehouse, so that the fruits and vegetables in the warehouse are in a dormant state and still maintain their original quality after leaving the warehouse. The so-called modified atmosphere preservation is to achieve the effect of preservation through gas adjustment.

2. Cold chain storage

Cold chain storage is generally used for fresh agricultural products, and goods and articles are stored and kept through warehouses. It is the products and articles that are temporarily stored in the process of product production and circulation due to pre-order or pre-market forecast.

3. Cold chain transmission

At a certain temperature, the sorting and packaging of fresh agricultural products can be realized by using the required transmission machinery, equipment and appliances.

4, cold chain loading and unloading

When loading and unloading the cold chain, the temperature of the goods should be detected. The unloading time of refrigerated and frozen articles needs to be sealed with unloading vehicles and warehouses according to the specified requirements to ensure that the temperature rise of articles is controlled within the allowable range during unloading. And when the unloading operation is interrupted, the door of the transportation equipment cabin should be closed immediately to keep the refrigeration system running normally.

5, cold chain information control

Information technology is the nervous system of modern cold chain logistics. With the support of the system information platform, it is easy to realize the strategic collaborative management of all resources of enterprises, reduce the cost of cold chain logistics, enhance the market competitiveness of cold chain logistics enterprises and improve the management level of cold chain logistics enterprises.

The key technologies of cold chain logistics information system include the following aspects: information collection and tracking technology, information transmission and exchange technology, and information processing technology.

6. Cold chain transportation

Cold chain transportation is an important part of cold chain logistics. The cost of cold chain transportation is very high, and it includes more complicated mobile refrigeration technology and incubator manufacturing technology. Cold chain transportation management contains more risks and uncertainties.

Cold chain transportation refers to the transportation that keeps the transported goods at a certain temperature during the whole transportation process, whether it is loading and unloading, changing the transportation mode or replacing the packaging equipment. The cold chain transportation mode can be road transportation, waterway transportation, railway transportation, air transportation, or a comprehensive transportation mode composed of multiple transportation modes.

7. Cold chain quarantine

Inspection of cold chain quarantine inspection needs to establish a standardized and orderly food quarantine inspection, arrange special personnel to manage transportation tools with large transportation volume, long distance and high pollution probability, do regular cleaning, disinfection and other sanitary treatments, and implement real-time monitoring and temperature recording of cold chain logistics to ensure the quality of food meets the requirements during transportation and ensure the safety and hygiene of imported food.
