Description

Technical Field

[0001] The utility model relates to the technical field of microbial fermentation, in particular to a defoaming device for microbial fermentation. Background Technique

[0002] Microbial fermentation is a biochemical process in which microorganisms convert raw materials into products required by humans through specific metabolic pathways under suitable conditions. This process can be aerobic or anaerobic and involves various microorganisms such as bacteria, yeasts, and molds. Microbial fermentation has a wide range of applications in the fields of food industry, pharmaceutical industry, energy industry, chemical industry, agriculture, and environmental protection. During the fermentation process, microorganisms produce gases such as carbon dioxide through metabolic actions. These gases form bubbles in the liquid, and the metabolites produced during the fermentation process all have surface activity and are prone to forming foam. These foams will have an adverse impact on microbial fermentation, so it is necessary to eliminate the foam.

[0003] In the existing defoaming devices for microbial fermentation, generally, defoaming is carried out by spraying water or defoaming agents. This will cause an increase in moisture during the microbial fermentation process, reducing the fermentation efficiency, and the defoaming agent will also cause a decrease in the purity of microbial fermentation, which is not conducive to production. Content of the Utility Model

When foam is generated in the fermentation tank, the waterproof motor can be started, so that the upper brush plate and the lower brush plate rotate.
