Biological fermentation tank

Abstract

The invention discloses a biological fermentation tank. The biological fermentation tank comprises a fermentation inner tank, wherein a processing top groove is fixedly connected to a top of the fermentation inner tank, an exhaust driving mechanism is fixedly connected to an end, extending to a top of the processing top groove, of a driving shaft rod, a quantitative discharging frame is fixedly connected to a position, located on an outer side of the driving shaft rod, of the top of the processing top groove, a bottom of the quantitative discharging frame fixedly communicates with a defoamingouter frame, material blocking filter holes are evenly formed in an outer side surface, close to a lower portion, of the defoaming outer frame, shoveling mechanisms are evenly and fixedly connected topositions, located below the defoaming outer frame, of a surface of the driving shaft rod, stirring serpentine rods are evenly and fixedly connected to an outer side surface, close to a bottom end, of the driving shaft rod, and a pressure relief spray pipe is fixedly connected to a surface of a top of the driving shaft rod and located on an outer side of the exhaust driving mechanism. The invention relates to the technical field of biological fermentation. The biological fermentation tank achieves a purpose of realizing periodic quantitative pressure relief of a fermentation tank and avoidingtraditional one-time pressure relief to cause a large amount of fermented products to be discharged together.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to a biological fermentation tank. Background technique [0002] Biological fermentation engineering is an important part of biological engineering. Microorganisms use carbohydrates to ferment to produce various industrial solvents and chemical raw materials. Ethanol, acetone-butanol, butanol-isopropanol, acetone-ethanol, 2,3-butanediol, and glycerol fermentations are some of the forms of solvent fermentation performed by microorganisms. [0003] For example, the Chinese invention publication number is: CN102206578B, a biological fermentation defoaming device, including a fermenter and a stirring shaft, a static cylinder with a static cavity is fixed on the inner top wall of the fermenter, and the side wall of the static cylinder is There is an exhaust pipe communicating with the static chamber of the stationary cylinder, the lower end of the stirring shaft passes t...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides a biological fermentation tank, which solves the problem that the traditional biological fermentation tank releases pressure only when the air pressure increases to a certain extent, and the fermented product that has been fermented and expanded is easily discharged together when the pressure is released. Causes waste of resources, high pressure environment is not conducive to biological reproduction and fermentation, and high pressure also increases the risk of biological fermentation, defoaming is achieved by adding defoaming agents during the fermentation process, defoaming agents have a certain inhibitory effect on biological fermentation efficiency , which is also not conducive to the problem of rapid biological fermentation
