We are a manufacturer of Outdoor Cooler Cart. Let me share with you how to properly pre-cool and keep a refrigerated truck.

　　Pre-cooling and insulation

　　The cargo must be pre-cooled to the required temperature, and the temperature of the cargo should be checked when loading; the refrigeration unit is used to maintain the temperature of the cargo, not to reduce the temperature of the cargo.

　　Many users of refrigerated trucks have a wrong concept. They always think that the refrigerating unit on the refrigerated truck can freeze or heat the goods loaded into the compartment to the required temperature at will. Therefore, load the cargo that is not enough for the transportation temperature requirement into the carriage, and then set the refrigeration unit to the required transportation temperature, and then reduce or increase the temperature of the cargo to the required temperature over a certain period of time. However, the fact is the opposite. Not only does the temperature of the goods fail to drop (or not rise), but the goods are damaged or deteriorated. Because the refrigerating unit of the refrigerated truck is not to reduce the temperature of the goods, but to maintain the temperature of the goods, it is like the quilt we used to sell cold drinks in the past to wrap the goods. When the external cold (heat) source flows into the compartment through radiation, conduction, and convection, it is taken away by the cold air blown by the refrigeration unit, and the heat source is isolated from entering the cargo.

　　Therefore, when loading goods, the temperature of the loaded goods must be measured first. If the set point temperature of the refrigeration unit is higher or lower than the temperature of the cargo, it is difficult for the temperature of the cargo in the compartment to reach the temperature required for transportation. The storage temperature of the goods must be consistent with the transportation temperature. If the temperature of the goods changes frequently, the moisture will be lost, which will cause the quality of the goods to change, which will shorten the shelf life of the goods.
