[0002] Foods that are packaged after being processed are called pre-prepared dishes. Pre-prepared dishes usually refer to pre-packaged dishes that are made from one or more edible agricultural products and their products through industrial pre-processing. The processing of pre-prepared dishes includes stirring, pickling, tumbling and kneading. Ready-to-eat or ready-to-heat pre-prepared dishes have been sterilized or cooked and can be eaten directly or after reheating after opening.

[0003] Pre-prepared dishes usually need to be processed. After the processing is completed, the pre-prepared dishes are usually subjected to cold storage and transportation operations through the supply chain to utilize the pre-prepared dishes, and then a dish processing supply chain cold storage and transportation device is used. The dish processing supply chain cold storage and transportation device in the prior art usually includes a transfer box, a sealing cover, a handle lock and a handle, etc. By placing an ice bag inside the transfer box and then placing the pre-prepared dishes inside the transfer box, the ice bag keeps the pre-prepared dishes at a cold storage temperature, and then the handle lock is used to lock the transfer box and the sealing cover, and the handle is used to move the transfer box to a transport vehicle or the like, and the pre-prepared dishes can be subjected to cold storage and transportation operations.
