A method for producing ethanol from root and tuber crops comprises pulverizing skin-removed raw material by subjecting skin-removed raw material to a first pulverization to give a first pulverization product, subjecting part of the first pulverization product to a second pulverization to give a second pulverization product,,mixing the rest part of the first pulverization product and the non-pulverized skin-removed raw material, and subjecting the resulting mixture to a first pulverization; mixing the pulverization product with enzyme, and subjecting the resulting mixture to enzymolysis; and fermenting the enzymolysis product. The inventive method has the advantage of low water consumption, low energy consumption, high facility utilization rate, and good pulverization effect. Moreover, the pulverization method in the present invention can well control particle size of the pulverized raw material, and achieve small and uniform particle size of the raw material. |
