Solid fermentation is mainly used for commercial enzyme production from fungi, among which the production of amylase with Aspergillus oryzae and the production of protease with Aspergillus and Mucor have a long history. Although this culture method is simple, the operating conditions are not easy to control. Most enzymes are now produced by liquid submerged fermentation.

It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0034] The invention provides Figure 1-Figure 9 As shown, a fermentation device for microbial strains comprises:

[0035] A fermentation tank 1 and a gas supply mechanism 3, wherein the gas supply mechanism 3 is arranged inside the fermentation tank 1, and the gas supply mechanism 3 includes a rotating tube 33 and a moving tube 34. A plurality of groups of rotating tubes 33 rotate inside the fermentation tank 1 to stir the fermentation material inside the fermentation tank 1, and at the same time, the rotating tubes 33 transport gas to the fermentation material from the inner bottom of the fermentation tank 1 and the inner side of the fermentation tank 1;

[0036] The movable tube 34 is movably installed on the rotating tube 33 . The movable tube 34 moves up and down reciprocatingly while the rotating tube 33 rotates. The movable tube 34 turns the fermentation material in the fermentation tank 1 up and down while conveying gas to the fermentation material inside the fermentation tank 1 .

[0037] Working principle: The present invention turns over the materials inside the fermentation tank 1 through a rotating and stirring pipeline, and at the same time, the nozzles 310 evenly distributed on the pipeline can continuously supply the gas required for the fermentation of the microorganisms inside the tank body; the turning structure that rotates synchronously at the bottom of the rotating rod 31 can turn over the fermented materials at the bottom of the tank body. Since the microorganisms will produce more water during the fermentation process, the turning structure prevents the materials at the bottom from being immersed in the bottom liquid. At the same time, the materials turned up from the bottom will also receive the gas supply from the pipeline nozzle 310, so as to obtain a better fermentation effect; by coordinating the corresponding driving mode and gas supply mode, the gas of the pipeline nozzle 310 can actually be continuously and evenly distributed to every corner of the fermentation tank 1;

[0038] The rotating tube 33 stirs and transports gas. The rotating tube 33 in the fermentation device rotates inside the fermenter 1 to stir the fermented material inside to increase the mixing uniformity of the material. At the same time, the rotating tube 33 is also responsible for transporting gas to the material from the inner bottom and inner side of the fermenter 1 to provide the oxygen required for microbial fermentation; the dynamic flipping and gas transportation of the mobile tube 34. The mobile tube 34 is installed on the rotating tube 33. As the rotating tube 33 rotates, the mobile tube 34 moves back and forth. This design enables the mobile tube 34 to flip the material up and down inside the fermenter 1, further promoting the mixing of the material and the uniform distribution of the gas.

[0039] Improve oxygen transfer efficiency. Through the coordinated work of the rotating tube 33 and the moving tube 34, oxygen can be more effectively transported to various parts of the fermented material, thereby improving the oxygen transfer efficiency and promoting the activity and fermentation efficiency of microorganisms. Enhance material mixing. The stirring and turning effects of the rotating tube 33 and the moving tube 34 help to evenly distribute the material inside the fermentation tank 1, reduce dead corners, and ensure the uniformity and consistency of the fermentation process. Optimize the fermentation environment. The dynamic pipeline design not only provides oxygen, but also reduces the deposition and stratification of materials during the fermentation process through the turning effect, providing a more suitable growth environment for microorganisms. Improve equipment utilization. This design allows the fermentation tank 1 to achieve more efficient gas supply and material stirring without adding additional equipment, thereby improving equipment utilization and economic benefits.
