In this process, a large amount of microbial culture fluid will be produced in the fermentation tank. These culture fluids contain both the desired fermentation products and various impurities and particulate matter. The residue filter device of a modern biological fermentation tank usually consists of a fermentation tank, a filter, and a connecting pipe. The fermentation tank is the main fermentation container for the cultivation and fermentation process of microorganisms; the filter is responsible for removing impurities in the fermentation fluid, and the connecting pipe is responsible for connecting the fermentation tank and the filter to form a closed circulation system.
