Microbial fermentation tank

Abstract

The invention relates to a microbial fermentation tank which comprises a tank body, a plurality of heating wires, a stirring shaft and a stirring shaft motor are arranged in the tank body; a plurality of stirring support rods are arranged at the lower end of the main shaft; a sealed rotary air inlet joint is arranged at the upper end of the main shaft; a plurality of air outlets are formed in the surface of the stirring support rod; a plurality of air inlet covers are further arranged in the tank body, and exhaust fans are rotationally arranged in the air inlet covers; the sealed rotary air inlet joint is connected with a plurality of air inlet covers through a hard multi-way pipe; a transmission gear is coaxially fixed to the main shaft, and a driven gear is coaxially fixed to the exhaust fan. According to the present invention, the single driving source is adopted to stir, such that the upper air can be heated, and the upper hot air can be introduced into the material; the introduced air is bubbled and floats upwards in the material, so that the air is provided and the heat is more uniform; meanwhile, moving and stirring of the materials are promoted, and breeding of microorganisms is facilitated.

Description

technical field [0001] The invention relates to the technical field of microbial fermentation tanks, and more specifically, relates to a microbial fermentation tank. Background technique [0002] With the development of genetic engineering, more and more microbial strains have been put into industrial production. In the existing industrial production of microorganisms, microbial fermenters are used for mass cultivation. Under suitable environmental conditions, microorganisms continuously absorb nutrients and carry out metabolic activities according to their own metabolic methods. If the assimilation is greater than the dissimilation, the amount of cytoplasm will continue to increase, the volume will increase, and effective metabolites will continue to be produced. Under certain physical and chemical conditions, microorganisms grow normally and reproduce at a high rate; if one or some environmental conditions change and exceed the range that organisms can adapt to, they will...

Problems solved by technology

[0004] The stirring device used in the traditional microbial fermentation tank adopts central stirring, and its contact area is extremely limited, it is difficult to coordinate the consistency of material, air and temperature, which is not conducive to the reproduction of microorganisms
