[0059] The working principle of the present invention is:

[0060] The driving motor 212 is energized, and the cleaning cylinder 201 is driven to rotate through the transmission plate 213, the gear 204 and the gear ring 203. At the same time, the water supply system 30 supplies water so that the nozzle on the water spray plate 301 sprays water, and then the food is transported to the inside of the cleaning cylinder 201 through the feeding hopper 206. When the cleaning cylinder 201 rotates, it drives a plurality of guide spiral strips 209 to rotate, so as to realize the rotating transportation of food. The food is cleaned and disinfected during the movement, and is discharged through the discharge hopper 214 after the cleaning is completed. When the amount of food in the cleaning cylinder 201 is different, the cleaning The cylinder 201 adjusts its height under the action of the support assembly. Under the action of the first elastic telescopic rod 207, the resistance rod 217 is always attached to the limit block 205 at different heights. The heavier the weight, the more the installation ring 208 drives the guide spiral strip 209 to move to the right, and the spiral angle of the guide spiral strip 209 will decrease. In this way, the conveying speed of the guide spiral strip 209 to the food will be reduced under the same rotation speed, so that the food can stay in the cleaning cylinder 201 for a longer period of time, and the cleaning effect can be guaranteed. When the cleaning cylinder 201 descends, the gate plate 304 is driven to descend through the L valve stem 305, thereby increasing the opening of the control valve body 302 and increasing the water supply. In this way, the water supply can be automatically adjusted according to the amount of food; the food after cleaning and disinfection is bagged, and then vacuum-sealed through the vacuum packaging cavity 10.

[0061] Example 2

[0062] The present invention also provides a method for automatic vacuum packaging of food, which utilizes the automatic vacuum packaging machine for food to perform packaging, and the specific packaging steps are as follows:
