[0002] Mobile cold storage is also known as combined cold storage, activity cold storage, and assembled cold storage. It is a new type of cold storage corresponding to the traditional civil cold storage. Mobile cold storage is mainly used for: food quick freezing processing and refrigeration (aquatic products, poultry, poultry, dispatched food, vegetables, fruits), slaughtering and processing factories (poultry, livestock), food processing plants, indoor assembled cold storage, seed storage room, biological and pharmaceutical finished products, and dairy product storage.

[0003] At present, the entry depth of mobile cold storage is relatively deep, and manual labor is required to frequently enter and exit the cold storage to retrieve goods. Manual handling is time-consuming and laborious. At the same time, because the cold storage door is large in size, when storing and retrieving goods, it is easy to cause a large amount of external hot air to mix with the cold air in the cabinet, causing serious loss of cold energy in the cold storage, thereby significantly increasing the power consumption of the cold storage.
