Generally, express delivery cannot express frozen food. Because it is impossible to guarantee the quality of food during the delivery process, there is no freezing equipment to transport frozen food. The railway has a special refrigerated carriage, and the freight department has a special refrigerated vehicle. It is ok to transport large quantities of frozen food, but it is difficult to transport a small amount of sporadic goods.

After the decision is feasible, the delivery can be prepared: it can be prepared as close as possible to 1 hour before picking up the goods, which can save the consumption of cold energy. Try to choose a thicker incubator, add dry ice to the packed food (dry ice is not allowed under air transportation conditions, only ice bags can be used), add 2 to 3 kilograms, put one third of the food in the ice bags, and seal the cartons.
