Abstract

The invention discloses a biomass continuous fermentation system, in particular to an anaerobic continuous fermentation system with farm straw being a carbon source. According to the technical scheme, biomass and a culture medium are prepared in a storage tank and conveyed into an anaerobic fermentation tank for fermentation through a shaftless spiral conveying device with a controllable solid-to-liquid ratio. The anaerobic fermentation tank is of a flexible structure and is extruded by external force to realize material mixing; due to the fact that biomass is in a particle state, in order to improve fermentation efficiency, biomass is conveyed into a grinding device during fermentation and enters the fermentation tank again after being ground; after fermentation is over, most residues will be extruded out of a tank body, only a small part of the residues will be left at the bottom of the tank to serve as seeds, and a new medium will be conveyed into the tank through the conveying device, so that efficient and continuous biomass fermentation is achieved.

Description

technical field [0001] The invention proposes a biomass continuous fermentation system, especially an anaerobic continuous fermentation system using agricultural stalks as a carbon source, belonging to the field of biological process engineering equipment. Background technique [0002] The equipment that uses straw biomass as carbon source for fermentation can only carry out non-continuous batch fermentation due to the influence of the state of straw particles. produce antagonism. Due to the limitation of biological utilization of biomass due to the above reasons, the present invention will realize continuous, high-efficiency and low-energy fermentation of biomass, and provide equipment solutions for the biotechnology development of biomass with straw as carbon source. Contents of the invention [0003] In order to solve the deficiencies in equipment technology required for continuous biomass fermentation, the technical solution of the present invention is to propose a de...
