Description

Technical Field

[0002] Mixed bacteria fermentation is also called mixed culture or mixed fermentation. This is a dual or multi-bacteria mixed culture method that is artificially optimized based on in-depth research on pure microbial culture. It belongs to the category of microbial ecological engineering. There are many types of microbial mixed culture, such as combined mixed culture, sequential mixed culture, co-immobilized cell mixed culture and mixed immobilized cell mixed culture. For example, a mixing device for microbial fermentation recorded in the patent with patent announcement number CN216359007U achieves the effect of reducing the strain transfer process and avoiding the strain from being contaminated by external bacteria through the mutual cooperation between the main tank, auxiliary tank, support foot, motor seat, motor, connecting shaft, main stirring shaft, main gear, auxiliary stirring shaft, slave gear, rotating shaft, transmission gear, adjusting rod, partition, through hole, connecting pipe and slide groove, which solves the problem that the strain may be contaminated by external bacteria during the transfer process of mixed bacteria culture. However, it is inconvenient to clean the fermentation cylinder of the device after use. Microorganisms may be attached to the inner wall of the tank for a long time because of the microorganisms stuck inside the fermentation cylinder, thereby affecting the subsequent fermentation of microorganisms. At the same time, the internal stirring rod cannot be disassembled, which is too troublesome to clean.

[0003] Based on this, a new aeration and mixing device for microbial fermentation is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content
