STRUCTURAL DESIGN OF BIOMASS CONTINUOUS FERMENTATION SYSTEM

Hou Zhe sheng, Fang Yan Zhao and You Yi

ABSTRACT:A continuous biomass fermentation system, in particular an anaerobic continuous fermentation system with agricultural straw as a carbon source. After the culture medium and biomass material storage tank configuration is completed, solid-liquid ratio by controllably shaftless screw feed device into the anaerobic fermentation tank fermentation. The anaerobic fermentation tank is a flexible structure that is squeezed by external forces to achieve material mixing. Since the biomass is in the form of particles, in order to increase the fermentation efficiency, the biomass is fed into the grinding device during fermentation and re-enters the fermenter after grinding. At the end of the fermentation, most of the residue will be squeezed out of the tank and a small part will remain at the bottom of the tank as a seed. New substrate will be fed into the feeder tank, to achieve efficient continuous fermentation of biomass.
