Cold chain transportation refers to transportation in which the transported goods always maintain a certain temperature in the whole transportation process, regardless of links such as loading, unloading, transporting, changing transportation modes, changing packaging equipment and the like. The cold chain transportation mode can be road transportation, waterway transportation, railway transportation and air transportation, and can also be a comprehensive transportation mode formed by a plurality of transportation modes. Cold chain transportation is an important link of cold chain logistics, has high cold chain transportation cost, contains more complicated mobile refrigeration technology and incubator manufacturing technology, and has more risks and uncertainties in cold chain transportation management.
The cold chain turnover box can keep refrigerated and frozen goods within a specific temperature range and plays an important role in cold chain transportation. Refrigerated and frozen goods need to be maintained within a specific temperature range to prevent spoilage and deterioration. The lack of a cold chain transfer box in cold chain transportation will result in difficulty in controlling the temperature of the commodity, which may be affected by external temperature changes, resulting in degradation of quality. There is no cold chain turnover box, and there is cross contamination risk between different commodities. For example, if fresh food is placed in the same transport vehicle as chemicals, it may cause the food to become contaminated, thereby affecting food safety. In addition, cold chain turn-around boxes are generally of a sturdy construction that protects the goods from vibration, shock and pressure. Without these boxes, the goods may be physically damaged during transportation, resulting in loss and wastage of goods. Meanwhile, the cold chain turnover box can improve logistics efficiency, simplify operation and storage, can be easily stacked and organized, reduces space occupation, and is compatible with transportation and storage facilities.
