The frozen food delivery must rely on special vehicles such as refrigerated truck. In addition to the dedicated vehicles for freezing or refrigerating, there must be a truck with the same body and machinery.
In addition, the vehicle must be equipped with frozen or refrigerated and insulated equipment. In the transportation process, special attention must be paid to the continuous refrigeration, because the microbial activity will be strengthened with the increase of temperature. If frozen food delivery cannot guarantee the conditions of continuous refrigeration, then the foods may decay and spoil when delivered.
