Let's recognize one thing: refrigerated trucks are not cold storage, the function of refrigeration units is insulation. In the minds of many people, the refrigeration unit on a refrigerated truck can freeze or heat the goods loaded into the compartment to the desired temperature.

In fact, refrigeration units are used to maintain the temperature of goods, not to lower the temperature of goods. It's a bit similar to the cotton quilt used when selling cold drinks in the past, which wraps the goods to maintain the temperature of the cold drinks.

When the external temperature enters the compartment of a refrigerated truck through radiation, conduction, and convection, it will be carried away by the cold air blown out by the refrigeration unit, isolating the heat source from entering the goods to ensure the temperature of the goods.

If goods with excessively high or low temperatures are loaded into the compartment of a refrigerated truck, and the refrigeration unit is set to the required transportation temperature for the transported goods, it is desired to lower or raise the temperature of the goods over a period of time

This approach is actually the opposite, as the temperature of the goods not only cannot be lowered (or raised), but also may cause damage or deterioration.

The cold air blown out by the refrigeration unit will cause a change in the temperature of the goods, resulting in the loss of moisture and a change in the quality of the goods. This can lead to a decrease in the quality of the goods, a shortened storage period, and even the deterioration of the goods.

It is very likely that the fresh beans you are pulling will be drier and lighter at the destination, causing trouble. That's also why refrigerated trucks usually go to cold storage to load goods, and rarely go directly to the fields to load goods.

After understanding the function of refrigerated trucks, we hope that the majority of refrigerated truck users can use them correctly to ensure the quality of the goods being transported.
