As the demand for fresh products increases in China, the cold chain logistics industry is growing. Compared with general warehousing and distribution, cold chain distribution has the following three distinctive features:.

1, the construction project investment, the system has a large and complex

Compared with room temperature logistics system, the logistics system is more demanding and complex, and it is a huge system project.

2、It is time-sensitive

Each link is required to have a high degree of organizational coordination. Due to the timeliness of perishable food, each link in the cold chain system is required to have high organization and coordination, so the operation of food cold chain is always related to the energy cost, and the effective control of operation cost is closely related to the development of food cold chain.

3、Higher cost

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

Development of Cold Chain Logistics

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

1、Temperature control and heat preservation

Constant Temperature Cold Storage: A cold storage with precise management requirements on the temperature and relative humidity for storing these items, including a constant temperature and humidity cold storage.

Controlled atmosphere cold storage: it can regulate the temperature, humidity, and control the storage process of oxygen, carbon dioxide and other gases, so that the storage process of fruits and vegetables in a dormant state, out of the warehouse is still to maintain the original quality. The so-called air-conditioning preservation is through the method of regulating gas to achieve the effect of preservation. Air conditioning is to reduce the oxygen concentration in the air from 21% to 3% ~ 5%, i.e., the preservation warehouse is based on high temperature cold storage, plus a set of air-conditioning system, the use of temperature and control of the oxygen content of the two aspects of the joint role, in order to achieve the purpose of inhibiting the respiratory state of fruits and vegetables after harvest.

2, cold chain storage

Cold chain warehousing cold chain warehousing is generally used for fresh and live agricultural products, goods, items through the warehouse for storage and safekeeping. It is in the process of product production and circulation, due to pre-order or advance market forecast and temporary storage of products and goods. It is a comprehensive place reflecting the material activities of the factory, a transit station connecting production, supply and marketing, and plays an important auxiliary role in improving production efficiency.

3、Cold chain transmission

Under a certain temperature, the classification and packaging of fresh agricultural products are realized through the use of necessary transmission machinery and equipment.

Focus of Cold Chain Warehouse Management

4、Cold chain loading and unloading

Cold chain loading and unloading should be carried out with an item temperature change detection. The unloading time of refrigerated and frozen goods should be required according to the regulations, and the management of unloading vehicles and unloading warehouses should be analyzed and sealed, so as to ensure that the temperature of the goods during the unloading period will be controlled in the permissible range of use. And when unloading operation is interrupted, the door of the transportation network equipment compartment should be closed in time to keep the refrigeration control system to maintain the normal operation of the society.

5、Cold chain informationization control

Information network technology is the modern cold chain logistics nervous system, through the support of the analysis system data information service platform, it is easy to realize the strategic cooperative management of all the resources of the enterprise, reduce the cost of cold chain logistics, enhance the cultural market economic competition of the cold chain logistics enterprise, and improve the level of management ability of the cold chain logistics enterprise.

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

6、cold chain delivery

Cold chain transportation is an important part of cold chain logistics. The cost of cold chain transportation is very high, and it contains more complicated mobile refrigerating technology and insulation box manufacturing technology. Cold chain transportation management contains more risks and uncertainties. Cold chain transportation refers to transportation that always keeps the transported goods at a certain temperature throughout the transportation process, whether it is loading and unloading, changing the mode of transportation, changing the packaging equipment, etc. The mode of cold chain transportation can be road transportation, waterway transportation, railroad transportation, air transportation, or a variety of modes of transportation composed of a comprehensive mode of transportation.

7、Cold chain quarantine

Inspection of cold chain quarantine requirements to establish a standardized and orderly food quarantine work, arrange special management of transport volume, distance, high probability of contamination of the transport, and do a good job of daily cleaning, disinfection and other health care work, the implementation of real-time monitoring of the cold chain logistics and temperature records, to ensure that the quality of food in the transport process in line with the requirements of food safety and health of imported food.
