Background technique

Cellulose solid-state fermentation ethanol refers to the process of enzymatic hydrolysis and saccharification fermentation in a water-insoluble solid matrix with a certain humidity in the presence of little free water. In the traditional fermentation reactor, the main shaft drives the stirring paddle to mix the materials. However, in the solid-state fermentation process of cellulose, the cellulose is relatively viscous during enzymatic hydrolysis and fermentation, and the fermented product is solid, so it is difficult to stir evenly, which will cause Uneven heat conduction during the fermentation process is not conducive to the measurement and control of the material temperature during the fermentation process, and is also not conducive to the full fermentation of the material, resulting in incomplete fermentation, so the fermentation efficiency is very low, the fermentation cycle is long, and in the later stage of fermentation, the cellulose Enzymes, yeast and nutrient solution are not all used up and are dumped together with the waste residue, which wastes resources and increases production costs.
