AI Technical Summary
In existing technologies, impurities easily clog the filter pores during the filtration of microbial fermentation broth, affecting filtration efficiency and making the impurities difficult to remove.
A microbial fermentation broth filtration device was designed, which uses a semi-circular scraper and a rotating shaft to separate microorganisms and metabolites through centrifugal force, and uses a scraper and a flexible brush to clean impurities. Combined with a suction head and a collection box to store impurities, the device achieves automated cleaning.
It improves filtration efficiency, avoids clogging of filter holes, simplifies the impurity cleaning process, and ensures continuous operation of the filtration device.
