Microorganism fermentation jar

Abstract

The invention belongs to the technical field of microorganism fermentation, in particular to a microorganism fermentation jar. The microorganism fermentation jar comprises an oxygen tank, a housing and a gas supply unit, wherein the gas supply unit is mounted in the housing, and comprises a motor, a rotating column, a baseplate and a ventilation plate. Through the adoption of the microorganism fermentation jar disclosed by the invention, through the cooperation of the oxygen tank, the housing and the gas supply unit, oxygen is provided for the inner part of a fermentation jar body; in the prior art, when oxygen is supplied for the fermentation jar, under the effect of buoyance, oxygen can quickly rise from the bottom end of the fermentation jar to the top end of the fermentation jar, so that liquid at the bottom end of the fermentation jar cannot sufficiently react with the oxygen; when the baseplate rotates, the ventilation plate is driven to stir in a solution at the same time, so that the reaction rate between the oxygen sprayed by the ventilation plate and the solution is accelerated; and in the rotating process of the ventilation plate, the effect of crushing oxygen bubbles isrealized, so that oxygen bubbles which are large in volume originally are separated into a plurality of oxygen bubbles which are small in volume, the contact area between the oxygen and the solutionis enlarged, and the fermentation effect of the fermentation jar is further accelerated.

Description

technical field [0001] The invention belongs to the technical field of microbial fermentation, in particular to a microbial fermentation tank. Background technique [0002] Fermentation tank refers to an industrial device used for microbial fermentation; its main body is generally a main cylinder made of stainless steel plate, with a volume of 1m 3 to hundreds of m 3 ;In the design and processing, attention should be paid to the tight and reasonable structure; the fermenter can withstand steam sterilization, has certain operating flexibility, minimizes internal accessories (avoid dead ends), has strong material and energy transfer performance, and can be adjusted to facilitate Cleaning, reducing pollution, suitable for the production of various products and reducing energy consumption; fermenters used for anaerobic fermentation such as the production of alcohol and solvents can have a relatively simple structure; used for aerobic fermentation such as the production of antib...

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology, solve the problem that when the volume of the bubbles at the bottom of the fermenter becomes smaller, the buoyancy of the bubbles increases, which makes the rising speed of the bubbles faster, thereby shortening the contact time and reaction effect between the bubbles and the liquid at the bottom of the fermenter , so that the liquid at the bottom cannot be fully supplied with oxygen, resulting in the problem that the liquid cannot be completely reacted; the present invention proposes a microbial fermentation tank
