[0003] At present, most air-drying devices dry the water droplets on the surface of vacuum-packed food by installing air-dryers. However, the position of the air-dryer is fixed, resulting in a fixed wind direction, incomplete air-drying of the water droplets, and thus reducing the air-drying effect of the vacuum bag. Moreover, the air-drying device can only air-dry one side of the vacuum packaging bag, and manual turning is required for air-drying the other side, increasing the labor intensity of workers and reducing work efficiency.

[0004] Therefore, an air-drying device for food vacuum bags is needed to solve the problems raised in the above background technique. Content of the Utility Model
