Fermentation fuel reactor and fermentation fuel production method

Abstract

The invention discloses a fermentation fuel reactor and a fermentation fuel production method, relates to the technical field of microbial fermentation equipment, and solves the technical problem in the prior art that relatively high production cost of a fermentation fuel is caused because cellulase and saccharomyces cerevisiae are wasted seriously. The fermentation fuel reactor includes a fermentation tank, a filter screen, a fluid pressurization conveying device, a large and small molecule separation device and an alcohol distillation tower; the large and small molecule separation device comprises a large molecule outlet and a small molecule outlet, the large molecule outlet is communicated with a material return port of the fermentation tank, and the small molecule outlet is communicated with a raw material inlet of the alcohol distillation tower; the large and small molecule separation device enables a cellulase, xylanase and saccharomyces cerevisiae-containing filtrate in a fermentation fluid inputted by the fluid pressurization conveying device to be outputted from the large molecule outlet and allow a remaining ethanol-containing filtrate in the fermentation fluid to be outputted from the small molecule outlet. The fermentation fuel reactor and the fermentation fuel production method are used for repetitive and circular utilization of cellulase and xylanase so as to reduce the production cost of the fermentation fuel.

Description

technical field [0001] The invention relates to the technical field of microbial fermentation equipment, and relates to a fermented fuel reactor that uses straw as a raw material, adopts a synchronous enzymolysis fermentation process, and can repeatedly utilize fermentation fluid containing cellulase, xylanase and Saccharomyces cerevisiae to produce fuel ethanol And a method of producing fermented fuel. Background technique [0002] Using renewable straw waste as raw material and using microbial fermentation technology to produce fuel ethanol has become an important strategic measure to alleviate my country's energy crisis, comprehensively utilize straw waste, and ensure energy security. However, large-scale and industrial production has not yet been formed. The main reason is that the cost of production is too high. [0003] The conversion of straw cellulose represented by corn to ethanol generally includes three stages of pretreatment, enzymatic hydrolysis and fermentation...
