Auxiliary device for microbial fermentation

Abstract

The invention relates to the technical field of biology, and in particular to an auxiliary device for microbial fermentation. The auxiliary device comprises a fermentation kettle and a support frame,wherein the fermentation kettle is arranged on the support frame; the bottom of the fermentation kettle is provided with a support base; a stirring rotating shaft is arranged on the support base through a bearing; a stirring blade is arranged on the stirring rotating shaft; the top of the fermentation kettle is provided with an air exchange mechanism; the main body of the air exchange mechanism isan air flow exchange box; the air flow exchange box is erected at an kettle opening of the top of the fermentation kettle; a flow gathering plate is arranged the inner cavity of the air flow exchangebox; the flow gathering plate is of an inner arc structure, and covers the top kettle opening of the fermentation kettle in a pot opening shape; the axial position of the flow gathering plate is provided with an opening; a sealing pipe sleeve is arranged in the opening; an air inlet pipe penetrates through the sealing pipe sleeve; and the tail end of the air inlet pipe extends into the inner cavity of the fermentation kettle. According to the invention, proper stirring operation is carried out on microbial fermentation, and the amount of carbon dioxide or oxygen in the fermentation kettle isconveniently controlled through an airflow conversion mechanism.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to an auxiliary device for microbial fermentation. Background technique [0002] Biotechnology is a technology that applies the basic principles of biology, chemistry and engineering to use organisms or their components to produce useful substances or provide certain services to humans. In recent years, with the rapid development of modern biotechnology, including the achievements of genetic engineering, cell engineering, protein engineering, enzyme engineering and biochemical engineering, the use of biotransformation characteristics to produce chemical products, especially those that are difficult to obtain by general chemical means New products, changing existing processes, and solving the two thorny problems of energy crisis and environmental pollution, which have been plagued for a long time, have attracted more and more people's attention, and some have been put into reality.

AI Technical Summary

Problems solved by technology

[0003] At present, in the research and development process of biotechnology products, the microbial fermentation raw materials are often stirred and mixed, but the stirring range of the current stirring device is small, especially the stirring blade only stirs the microbial fermentation raw materials at a fixed height position. Not sufficiently uniform, for this reason, a stirring device for microbial fermentation is now provided

[0004] Chinese patent (authorized announcement number: CN108998350A) discloses a stirring device for microbial fermentation, which assists microbial fermentation through up-and-down stirring operations, but there are obvious defects in this patent, and the actual operation of microbial fermentation and stirring requires a little Just wait for stirring, similar to the operation of this device, it will cause a lot of damage to microorganisms
