At present, from the perspective of users who use transport refrigeration units, there are only a few food factories in China that purchase their own transport refrigeration units, or strictly require dealers to use regular transport refrigeration units to transport food. The vast majority of food factories carry food for food. It is not standardized. Whether it is an air-conditioned car or a quilt car, the food factory does not have strict requirements on the vehicle.
In addition, the reason why the cold chain transportation link does not have a strict supervision system is also reflected in the problem of the refrigerating temperature of the food before, during and after transportation. In foreign countries, chilled foods are always kept strictly at a constant temperature. The temperature of food in China is not particularly strict. For example: Shijingqi is equipped with a transport refrigeration unit in the cold storage of °C. At first, the mud in the car is likely to have not been loaded with a pass-through cargo. When the temperature in the car finally reaches --18 ° C, the destination has arrived, and the refrigerating temperature of the destination may be another. temperature. These ever-changing temperatures degrade or even degrade the quality of the food. For these, China does not have strict standards to implement, and there is no effective mechanism to supervise implementation.
In the technology of transporting refrigeration units, there is no high demand in China, and Chinese users are mostly responsible for dealing with them. The vehicles exported to foreign countries are much more advanced. It is also often equipped with a backup power source that plugs into the household power source when not in use. The constant temperature in the car is always maintained, while in the daytime it is cooled by the refrigeration unit. There is also a new technology on the market that is not widely used. In order to solve the problem that the temperature inside the compartment is not constant under the idle state.
