A paper to understand the composition of the cold chain warehousing management process
1. Temperature control insulation
Constant temperature cold storage: A cold storage with precise requirements for the temperature and humidity of stored items, including constant temperature and humidity storage.
Air-conditioning cold storage: It can not only regulate the temperature and humidity in the warehouse, but also control the content of oxygen, carbon dioxide and other gases in the library, so that the fruits and vegetables in the library are in a dormant state, and the original quality is maintained after the storage. The so-called modified atmosphere is through the gas adjustment method to achieve the effect of preservation. Gas regulation is to reduce the oxygen concentration in the air from 21% to 3% to 5%. That is, the fresh storage tank is based on the high temperature cold storage, plus a set of air conditioning system, which uses the temperature and the control oxygen content. The role is to inhibit the post-harvest breathing state of fruits and vegetables.
2. Cold chain storage
Cold chain storage cold chain storage is generally used for fresh agricultural products, and the storage and storage of goods and articles through warehouses. During the production and distribution of products, products and articles are temporarily stored due to pre-order or market forecast. It is a comprehensive place that reflects the status of the material activities of the factory. It is a transfer station connecting production, supply and sales, and plays an important supporting role in promoting the efficiency of production.
3. Cold chain transmission
At a certain temperature, through the use of the required transmission machinery, equipment, etc., the sorting and packaging of fresh agricultural products can be achieved.
4. Cold chain handling
The temperature detection of the item is carried out during cold chain loading and unloading. The unloading time of refrigerated and frozen goods needs to be sealed according to the requirements of the unloading vehicle and the unloading warehouse to ensure that the temperature rise of the articles during unloading is controlled within the allowable range. When the unloading operation is interrupted, the transportation equipment door should be closed immediately to keep the refrigeration system running normally.
5. Cold chain information control
Information technology is a modern cold chain logistics nervous system. Through the support of the system information platform, it is easy to realize strategic cooperative management of all resources of the enterprise, reduce the cost of cold chain logistics, enhance the market competition of cold chain logistics enterprises, and improve the management level of cold chain logistics enterprises.
The key technologies of the 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 transport
Cold chain transportation is an important part of cold chain logistics. The cold chain transportation cost is high, and it contains more complicated mobile refrigeration technology and insulation box manufacturing technology. Cold chain transportation management contains more risks and uncertainties. Cold-chain transportation refers to the transportation of the goods to be kept at a certain temperature during the whole process of transportation, whether it is loading and unloading, changing the transportation mode, or changing the packaging equipment. The cold chain transportation mode can be road transportation, water transportation, railway transportation, air transportation, or an integrated transportation method composed of various transportation modes.
7. Cold chain quarantine
To test the cold chain quarantine inspection, it is necessary to establish a standardized and orderly food quarantine inspection work, and arrange special personnel to manage transportation vehicles with large transportation volume, long distance and high probability of pollution, do a good cleaning and disinfection, and implement cold chain logistics. Real-time monitoring and temperature recording work to ensure that the quality of food in the transportation process meets the requirements, and to ensure the safety and hygiene of imported food.
