The invention provides a
raw material storage and
processing method applied to production of bioethanol, and belongs to the field of
biomass recycling technological development. According to the
raw material storage and
processing method applied to the production of the bioethanol, the storage cost is effectively controlled, and the conversion efficiency of bioethanol products is improved. The method comprises the steps of a, adopting a
raw material with 20%-70%
moisture content, and conducting smashing with different particle sizes according to initial
moisture content; b, preparing additive, wherein
lactic acid bacteria fungicide and hemicellulase are dissolved into
sterile water which accounts for 2%-3%
dry weight of the raw material, and based on the
dry weight of the raw material, the dosages of the
lactic acid bacteria fungicide and hemicellulase are 103-105 cfu / g and 0.15-0.45 IU / g respectively; c, mixing the raw material with the additive, compacting the mixture, venting gas and storing for at least 21 days to obtain the stored material; d, conducting drip washing on 5%-10% of the stored material through the
sterile water, conducting
extrusion, taking the liquid component to mix with an MRS
nutrient solution, and after cultivating the
mixed solution for 6-12 hours at 30 DEG C, refrigerating the
mixed solution for standby application; e, when storage in next batch is conducted, replenishing hemicellulase 0.5-0.75 times which is used in a previous batch into the
nutrient solution, so that the regenerated storage additive is obtained so as to replace the additive needed by continuous storage; f, fully mixing the remaining
storage material with the
solid after drip washing to make the mixture used for pretreatment of production of ethyl
alcohol.
