[0028] Subsequently, when the fermentation tank 1 is no longer in use, the water in the water tank 7 is pumped into the output pipe 706 by starting the pump 705. After the water passes through the straight plate 703 and enters each high-pressure nozzle 704, the high-pressure nozzle 704 can spray high-pressure water at the inner wall of the fermentation tank 1. At this time, the motor 3 drives the rotating rod 301 and the distribution plate 4 to rotate together, and the distribution plate 4 can drive the connecting plate 6 and the scraper 2 604 to rotate. Since the spring 2 602 presses the scraper 2 604 to always keep close to the inner wall of the fermentation tank 1, it is convenient for the scraper 2 604 to scrape and clean the inner wall of the fermentation tank 1 during the rotation process. The water spraying of the high-pressure nozzle 704 can speed up the cleaning speed of the inner wall of the fermentation tank 1, improve the cleaning effect of the inner wall of the fermentation tank 1, and eliminate the need for manual cleaning, which is time-consuming and labor-saving.
