[0002] Enzyme preparations refer to a class of substances extracted from organisms that possess enzymatic properties. They are primarily composed of enzyme proteins and other cofactors and are typically used to accelerate or catalyze specific chemical reactions. There are two methods for producing enzymes through fermentation: solid-state fermentation and submerged fermentation. Solid-state fermentation is primarily used for commercial enzyme production derived from fungi. The production of amylase using Aspergillus oryzae and proteases using Aspergillus and Mucor have a long history in China and Japan. While this culture method is simple, the operating conditions are difficult to control. Currently, most enzymes are produced through submerged fermentation.

[0003] During operation, the existing liquid fermentation equipment for microbial strains has low microbial growth efficiency due to insufficient oxygen distribution, which affects the operating efficiency.

[0032] During use, the fermentation liquid enters the composite shell 11 from the feed pipe 16 to facilitate subsequent fermentation. When the liquid is fermenting, gas is supplied to the composite shell 11 through the gas supply mechanism 18 to meet the oxygen demand of microbial fermentation and avoid local oxygen deficiency, which affects the growth and fermentation of microorganisms. The motor 4 drives the transmission mechanism 5 to operate, and the transmission mechanism 5 drives the central shaft 12 to rotate, so that the rotating mechanism 17 stirs the liquid to achieve the effect of promoting the uniform distribution of microorganisms and ensuring the uniform growth of the bacteria. Secondly, the rotation of the rotating mechanism 17 promotes the mixing of oxygen and liquid to achieve the effect of satisfying the respiration of microorganisms, promoting microbial metabolism, and promoting full contact between microorganisms and nutrients. Stirring can form tiny bubbles of air introduced and evenly distribute them in the fermentation liquid, increase the gas-liquid contact area, increase the dissolution rate and dissolution amount of oxygen, and ensure that the microorganisms have enough oxygen to carry out metabolic activities. 1 is provided with a processing mechanism 2 at the bottom. The processing mechanism 2 rotates to drive the liquid at the bottom of the inner wall of the composite shell 11 to roll, thereby preventing the bottom material from being immersed in the liquid produced by fermentation, reducing microbial growth inhibition and fermentation abnormalities caused by local hypoxia of the material and accumulation of metabolites, etc., helping to maintain the activity of microorganisms and the stability of fermentation, and improving the quality of enzyme preparations. Stirring can suspend microbial cells in the fermentation liquid, avoid the occurrence of cell precipitation, and ensure the normal progress of the fermentation process. After the fermentation is completed, the liquid is discharged from the liquid outlet pipe 15 to meet the needs of subsequent operations. When the inside of the composite mechanism 1 needs to be cleaned, a cleaning liquid is injected into the composite mechanism 1, and then the friction mechanism 3 is driven to rotate through the central rotating shaft 12 to rub the inner wall of the composite shell 11, thereby cleaning the inner wall, reducing the residual impurities on the inner wall surface, and avoiding the long-term adsorption of impurities to cause corrosion to the equipment, thereby extending the service life of the components.
