Description

Technical Field

[0001] The utility model belongs to the technical field of microbial fermentation tanks, and in particular relates to a microbial fermentation tank with a stirring structure. Background Art

[0002] Microbial fermentation refers to the process of using microorganisms to convert raw materials into products needed by humans through specific metabolic pathways under suitable conditions. Fermentation tank refers to an industrial device used for microbial fermentation. Its main body is generally a cylindrical cylinder made of stainless steel plates with a volume of 1m3 to hundreds of m3. Fermentation tank is a key equipment in the microbial production process. Microorganisms need to grow, metabolize and eventually produce fermentation products in a suitable environment. The microbial fermentation process is divided into aerobic fermentation and anaerobic fermentation according to the fermentation conditions. Aerobic fermentation methods include liquid surface culture fermentation, fermentation on the surface of porous or granular solid culture medium and deep fermentation with oxygen. Anaerobic fermentation uses deep fermentation without oxygen. Therefore, both aerobic and anaerobic fermentation can be achieved through deep culture, and this culture is completed in a cylindrical fermentation tank with a certain diameter-to-height ratio. Publication No.: CN216584997U discloses a microbial fermentation tank with an air intake treatment device, which specifically relates to the technical field of microbial fermentation tanks. Most of the existing devices do not have a good removal of dust and other microorganisms in the air. The fermentation tank is easily infected with miscellaneous bacteria during the process of culturing microorganisms, and the amount of air injected cannot be controlled according to different needs. It includes a connecting box and a fan, a filter component is installed inside the connecting box, and an adjustment component is installed on the side surface of the connecting box. By setting the filter component in conjunction with an ultraviolet sterilization lamp, miscellaneous bacteria and dust particles in the injected gas can be removed to prevent the microorganisms inside the fermentation tank body from being infected, thereby improving the product quality. The dust particles blocked by the dustproof filter will accumulate inside the dust collecting chamber. By setting the adjustment component, the water storage tank and the nozzle, the different needs of different microorganisms for humidity and gas volume during fermentation can be met to ensure the working efficiency of the microorganisms and improve the product quality.

[0003] However, there are some problems with the prior art: the stirring structure of the existing microbial fermentation tank performs unidirectional stirring in one direction, so that the stirring structure cannot improve the mixing efficiency of the raw materials when stirring the raw materials, and when the raw materials are discharged from the tank body through the discharge pipe, due to the poor fluidity of the raw materials, the raw materials are easily blocked in the discharge pipe, thereby affecting the discharge speed and efficiency. Therefore, we propose a microbial fermentation tank with a stirring structure. Utility Model Content
