With the increase in demand for fresh products in China, the cold chain logistics industry has also developed rapidly. Compared with general warehousing and distribution, cold chain distribution has the following three obvious characteristics:

1. Large construction investment, large and complex system

The construction investment of cold chain distribution is higher and more complicated than ordinary room temperature logistics system,cold chain which is a huge system project.

2. Time-sensitive

Due to the timeliness of perishable food, it is required that each link in the cold chain system has higher organizational coordination. Therefore, the operation of food cold chain is always associated with energy cost,cold warehouse and effective control of operation cost is closely related to the development of food cold chain.

3. Higher costs

In order to ensure that fresh fruits and vegetables, etc. are always under the specified low-temperature conditions in all stages of circulation, it is necessary to install temperature-control equipment, use refrigerated trucks or low-temperature warehouses, and adopt advanced information systems. The cost of cold chain logistics for agricultural products is on the high side compared to other logistics systems.

Based on the above three characteristics, the requirements for cold chain warehouse management are relatively high. Then where is the focus of cold chain warehouse management?

1. Temperature control and heat preservation

Constant temperature cold storage: cold storage with precise requirements on temperature and humidity of storage items, including constant temperature and humidity cold storage.

Gas-conditioned cold storage: it can not only regulate the temperature and humidity inside the warehouse, but also control the content of oxygen, carbon dioxide and other gases inside the warehouse, so that the fruits and vegetables in the warehouse are in a dormant state, and still maintain the original quality after leaving the warehouse. The so-called gas-conditioning preservation is through the gas adjustment method, to achieve the effect of preservation. Gas conditioning is the oxygen concentration in the air from 21% down to 3% to 5%, that is, the freshness of the library is based on high-temperature cold storage, plus a set of gas conditioning system, the use of temperature and control of the oxygen content of the two aspects of the common role, in order to achieve the inhibition of fruits and vegetables after the harvest respiratory state.

2. Cold chain storage

Cold chain warehousing is generally used for fresh agricultural products category, through the warehouse storage and custody of goods and articles. It is the product production, circulation process due to the order front or market forecast front and make products, items temporarily stored. It is a comprehensive place that centrally reflects the status of material activities in the factory, and is a transit station connecting production, supply and sales, and plays an important auxiliary role in promoting the efficiency of production.

3. Cold chain transmission

Under a certain temperature, through the use of the required transmission machinery, equipment and appliances, etc., it achieves the sorting and packing of fresh agricultural products.

4. Cold chain loading and unloading

Cold chain loading and unloading is subject to temperature testing. The unloading time of refrigerated and frozen goods should be in accordance with the stipulated requirements, and the unloading vehicle and the unloading warehouse should be sealed, so as to ensure that the temperature of the goods during unloading can be controlled in the permissible range. And when the unloading operation is interrupted, the door of the transportation equipment compartment should be closed in time to keep the refrigeration system in normal operation.

5. Cold chain information control

Information technology is the nerve system of modern cold chain logistics. Through the support of systematic information platform, it is easy to realize the strategic and cooperative management of all the 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 cold chain logistics informatization 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 high, and it contains more complicated mobile refrigeration technology and insulation box manufacturing technology, and the management of cold chain transportation contains more risks and uncertainties. Cold-chain transportation (Cold-chain transportation), refers to the whole process of transportation, whether it is loading and unloading handling, change the mode of transport, replacement of packaging equipment, etc., so that the transported goods always maintain a certain temperature of transportation. Cold chain transportation can be road transport, waterway transport, railroad transport, air transport, or a variety of modes of transport composed of a comprehensive mode of transport.

7. Cold chain quarantine

Inspection of cold chain quarantine inspection requires the establishment of standardized and orderly food quarantine inspection work, arrange for special management of transport volume, distance and high probability of contamination of the means of transport, do a good job of routine cleaning, disinfection and other sanitary treatment, and the implementation of real-time monitoring of the cold chain logistics and temperature records, to ensure that the quality of the food in the process of transportation state meets the requirements to ensure that the imported food is safe and hygienic.

Cold chain warehouse management is in the core position in the cold chain system, and it is an important link to guarantee the feasibility and reliability of the whole cold chain management, so the importance of doing a good job in cold chain warehouse management is self-evident!
