[0002] Fermentation refers to the process in which people use the life activities of microorganisms under aerobic or anaerobic conditions to prepare the microbial cells themselves, or direct metabolites or secondary metabolites. It is mainly used in the food industry, biology, chemical industry and other fields. When fermenting items, fermentation tanks will be used accordingly. Fermentation tanks can provide an optimal nutrition, pH, temperature, and oxygen supply for the growth of the fermented items, so that the fermented items can grow rapidly.

[0003] Prior art, such as the utility model patent document with authorization announcement number "CN220467938U" and patent name "A Fermentation Tank", discloses a fermentation tank, which includes a fermentation tank body, the upper end surface of the fermentation tank body is provided with a feeding pipe for loading materials, the interior of the fermentation tank body is provided with a stirring device for stirring raw materials, the lower end surface of the stirring device is fixedly installed with a rotating mechanism for improving the stirring effect of the raw materials, and the left side of the rotating mechanism is slidably installed with a rolling mechanism for auxiliary stirring.

[0004] During a normal fermentation process, materials often stick to the tank wall, causing problems such as material drying and agglomeration, and reduced mass transfer and oxygen transfer performance. Therefore, after the fermentation is completed, the materials on the tank wall need to be scraped off. However, in actual use, the above patent requires manual scrubbing. Since the tank body is large, manual scraping usually results in sanitary dead corners, resulting in unclean scrubbing. Utility Model Content

[0033] The manhole 17 is used for easy maintenance; the operating effect of the tank body 101 during closed operation can be observed through the sight glass 18;
