Refrigerated transportation is established with the progress of science and technology and the development of refrigeration technology. It is a low-temperature logistics process based on refrigeration technology and with refrigeration technology as the means. It is a special logistics form that needs to use Kelly refrigerator, and needs to pay attention to the transportation process, time control, transportation type, and the proportion of logistics costs is very high.

1. Scope of application of cold chain logistics

1. Primary agricultural products: vegetables, fruits; Meat, poultry, eggs; Aquatic products, flower products.

2, processed food: frozen food, poultry, meat, aquatic products and other packaged cooked food, ice cream and dairy products; Fast food ingredients.

3. Special products: medicine.

Since the food cold chain is a supply chain system with the purpose of ensuring the quality of perishable foods and maintaining a low temperature environment as the core requirement, it has higher and more complex requirements than the general room temperature logistics system, and the construction investment is also much larger, and it is a huge system project.

Since the timeliness of perishable foods requires higher organizational coordination of all links of the cold chain, the operation of the food cold chain is always related to energy consumption costs, and effective control of operating costs is closely related to the development of the food cold chain.

Second, cold chain logistics precautions

1, in the cold chain logistics transportation and distribution, there are several models for you to choose: ice insulation car, mechanical refrigerated truck, open car and ice transportation. These three kinds of cold chain transportation can choose the models and methods they need according to the different nature of the items to be transported, so as to prevent inconvenience and unnecessary losses to themselves.

2, because it is a cold chain logistics transport model, so there must be a refrigeration system in the car, we should be different according to the transport of goods, to adjust a suitable temperature for the preservation of transport goods to transport, so as to achieve the best transport preservation effect, but also to prevent the trouble caused by temperature regulation.

3, when choosing cold chain logistics transportation, you need to tell the logistics personnel to keep the temperature in the cold chain car between 2 degrees Celsius and 8 degrees Celsius. Rather than the temperature is very cold or very mild, do not use the container as a cooler.

4, for the fresh food that requires the temperature during transportation to be guaranteed within 1 degree Celsius of its freezing point or damage point, the frozen container should be pre-cooled before shipping these fresh food, and it is better to use the "cold air channel" to quickly install fresh food. The belt engine should be used to maintain continuous operation of the refrigerated container refrigeration system and avoid temperature fluctuations.

5, summer hot Popsicle ice cream demand up, why the Popsicle snow to use minus 18 degrees Celsius refrigerated truck to refrigerate transportation? Because the cargo box of the refrigerated truck needs a strictly guaranteed sealing degree to reduce the heat exchange with the outside world, it also ensures that the temperature in the refrigerated cargo box is kept low.

6, when transporting liquid products, choose a refrigerated container with strong heat insulation, which can maintain a constant temperature, but also block the high temperature outside, to prevent liquid deterioration and volatilization.
