Description

Technical Field

[0001] This utility model relates to the field of bioreactor technology, and in particular to a bioreactor. Background Technology

[0002] Microbial fermentation refers to the process by which microorganisms, under suitable conditions, transform raw materials into products needed by humans through specific metabolic pathways. Microbial fermentation can be broadly classified into aerobic fermentation, anaerobic fermentation, and facultative anaerobic fermentation. Among these, aerobic fermentation requires a high oxygen concentration within the reactor.

[0003] A search revealed that patent CN218932128U discloses a microbial fermentation reactor. During normal use, the lid is placed on the fermentation tank, and the stirring mechanism is located inside the fermentation tank. When cleaning is required after use, the lifting motor is activated, driving the screw to rotate. The screw drives the slider to slide upward, and the slider moves the lid upward through two support rods, thereby moving the stirring mechanism out of the fermentation tank. At this time, the inner cavity of the fermentation tank can be rinsed, and the stirring mechanism can also be rinsed, achieving thorough cleaning and solving the problem of existing microbial fermentation reactors being difficult to clean.

[0004] In actual use, although the above scheme is equipped with a stirring mechanism to stir the materials in the fermentation tank, it is not convenient to introduce fresh air into the fermentation tank when the tank lid is closed. Therefore, it affects the fermentation efficiency of the materials during aerobic fermentation. Utility Model Content
