Abstract

The present invention relates to the field of biological fermentation technology, and discloses a fermentation device for microbial strains, which includes a fermentation tank and a gas supply mechanism. The gas supply mechanism is arranged inside the fermentation tank. The gas supply mechanism includes a rotating pipe and a moving pipe. Multiple groups of rotating pipes rotate inside the fermentation tank to stir the fermentation materials inside the fermentation tank. At the same time, the rotating pipes supply gas to the fermentation materials from the inner bottom and the inner side surface of the fermentation tank. In the present invention, the materials inside the fermentation tank are turned over by the rotating and stirring pipes. At the same time, the uniformly distributed nozzles on the pipes can continuously supply the gas required for the fermentation of the microbial strains inside the tank body. The turning structure that rotates synchronously at the bottom of the rotating rod can turn over the fermentation materials at the bottom of the tank body. Since a large amount of water will be generated during the fermentation process of the microbial strains, and the materials turned up from the bottom will also receive the gas supply from the pipe nozzles, a better fermentation effect can be obtained.

Description

Technical Field

[0001] The present invention relates to the technical field of biological fermentation, and specifically relates to a fermentation device for microbial strains. Background Art

[0002] There are two fermentation production methods for microbial enzyme preparation strains. One is solid fermentation, and the other is liquid deep fermentation. Solid fermentation is mainly used for the commercial production of enzymes from fungi. Among them, the production of amylase with Aspergillus oryzae, and the production of protease with Aspergillus and Mucor have a long history. Although this cultivation method is simple, the operating conditions are not easy to control. Now most enzymes are produced by liquid deep fermentation culture.

[0003] The prior art discloses a liquid fermentation device for enzyme preparation microbial strains and its fermentation process (publication number: CN112251338B). The fermentation process carried out by this device solves the problems of insufficient stirring and uneven distribution of dissolved oxygen during fermentation, which affect the fermentation effect, and can defoam without affecting the dissolved oxygen. However, this technical solution still has the following technical problems: This solution promotes the increase of the dissolved oxygen concentration in the fermentation broth by stirring, but the actual air distribution situation is related to the setting method of the atomizing nozzle. Therefore, in the actual operation process, the air required by the microorganisms cannot be evenly distributed to all positions of the fermentation material. Summary of the Invention

[0034] The invention provides a Figures 1-9 fermentation device for microbial strains as shown in

[0035] a fermentation tank 1 and an air supply mechanism 3, the air supply mechanism 3 is arranged inside the fermentation tank 1, the air supply mechanism 3 includes a rotating tube 33 and a moving tube 34, multiple groups of rotating tubes 33 rotate inside the fermentation tank 1 to stir the fermentation materials inside the fermentation tank 1, and at the same time, the rotating tube 33 conveys gas to the fermentation materials from the inner bottom and the inner side surface of the fermentation tank 1;

[0036] the moving tube 34 is movably installed on the rotating tube 33, the moving tube 34 reciprocally moves up and down while the rotating tube 33 rotates, and while the moving tube 34 turns the fermentation materials inside the fermentation tank 1 up and down, it conveys gas to the fermentation materials inside the fermentation tank 1.

[0037] Working principle: In the present invention, the materials inside the fermenter 1 are agitated by a rotating and stirring pipeline. Meanwhile, the spray nozzles 310 evenly distributed on the pipeline can continuously supply the gases required for the fermentation of the microbial strains inside the tank body. The agitation structure that rotates synchronously at the bottom of the rotating rod 31 can agitate the fermented materials at the bottom of the tank body. Since a large amount of water is generated during the fermentation process of the microbial strains, the agitation structure prevents the materials at the bottom from being continuously immersed in the bottom liquid. At the same time, the materials agitated from the bottom will also receive the gas supply from the pipeline spray nozzles 310, achieving a better fermentation effect. By coordinating with the corresponding driving method and gas supply method, in fact, the gases from the pipeline spray nozzles 310 can be continuously and evenly distributed to every corner of the fermenter 1;

[0038] The rotating pipe 33 for agitation and gas transportation rotates inside the fermenter 1 to agitate the fermented materials inside, so as to increase the mixing uniformity of the materials. At the same time, the rotating pipe 33 is also responsible for transporting gases to the materials from the inner bottom and inner side of the fermenter 1 to provide the oxygen required for microbial fermentation; The dynamic agitation and gas transportation of the moving pipe 34. The moving pipe 34 is installed on the rotating pipe 33. As the rotating pipe 33 rotates, the moving pipe 34 performs reciprocating lifting and lowering movements. This design enables the moving pipe 34 to agitate the materials up and down inside the fermenter 1, further promoting the mixing of the materials and the uniform distribution of the gases;

Through the collaborative work of the rotating pipe 33 and the moving pipe 34, oxygen can be more effectively transported to each part of the fermented materials, improving the oxygen transfer efficiency, thereby promoting the activity and fermentation efficiency of the microorganisms; Enhance the material mixing. The agitation and turning effects of the rotating pipe 33 and the moving pipe 34 contribute to the uniform distribution of the materials inside the fermenter 1, reducing dead corners and ensuring the uniformity and consistency of the fermentation process; Optimize the fermentation environment.
