The development of cold chain logistics is getting faster and faster. Refrigerator trucks play a decisive role, mainly to protect food safety and ensure the quality of fresh food. Many people think that a refrigerated truck is like a cold storage, and it is free to freeze the cargo loaded into the compartment to the necessary temperature. This is a big mistake. Its refrigeration unit is only used to maintain the temperature of the cargo, not to reduce the temperature. The main purpose of refrigerated trucks is to make perishable and perishable foods such as fruits, seafood, frozen meat and vegetables. What does a refrigerated truck do for food? When the outside temperature enters the compartment of the refrigerated truck through radiation, conduction, and convection, it will have a qualitative impact on the cargo, so the refrigerated truck will have to act as a refrigeration unit to take away the outside temperature, so as to ensure the temperature of the cargo. Keep the goods at the necessary transportation temperature, otherwise it may deteriorate. The temperature of the goods must be checked at the time of loading. If the temperature is too high or too low to enter the car, it is thought that setting the refrigeration unit to the necessary transport temperature of the goods to be transported is just a counterproductive. If you can't lower it (or increase it), it will damage the goods. The cooling of the refrigeration unit will cause the temperature of the cargo itself to change, causing it to lose water. This will also cause changes in the quality of the cold cargo, which will lead to a decline in the quality of the cargo and even mildew. This is why refrigerated trucks are the reason to go to the cold storage instead of running to the goods production site. In fact, my recent understanding of refrigerated trucks reminded me of the foam box I used when I was a child at home to sell popsicles. It contained a layer of quilts so that the temperature of the popsicles could be maintained without melting. Think about the time when I think about it now! The principle of a refrigerated truck is similar to this foam box, except that we have mechanized its innovation.
