[0002] In the process of microbial fermentation, fermentation tanks are widely used to promote microbial fermentation. Microbial fermentation refers to the process of using microorganisms to convert raw materials into products needed by humans through specific metabolic pathways under suitable conditions. The production level of microbial fermentation mainly depends on the genetic characteristics of the strain itself and the culture conditions.

[0003] For example, the utility model disclosed in the publication (announcement) number: CN217459370U discloses a vertical fermentation tank that is convenient for feeding, which is characterized in that: a feed pipe is provided at the middle of the top of the tank body, and a number of feed pipes are evenly distributed around the feed pipe, and the feed pipe and the several feed pipes are connected to the fermentation cavity set inside the tank body, and a pipe cover is provided at the top of each group of feed pipes, and the pipe cover is fixed to the feed pipe by welding or bolting, and a number of through holes are symmetrically provided on the pipe cover. In this case, by setting up multiple groups of feed structures, different fermentation raw materials can be added to the fermentation tank at the same time, which not only makes the feed distribution uniform, but also improves the original feed efficiency and effectively avoids cross contamination of various fermentation raw materials.

[0004] The device of the utility model avoids cross-contamination of various fermentation raw materials by setting up multiple groups of feeding structures. However, multiple feeding structures are directly in contact with the outside air, which increases the area in contact with the outside air, increases the probability of the fermentation tank being contaminated by external microorganisms, and affects the fermentation process.
