METHOD FOR PRODUCING ETHANOL FROM ROOT AND TUBER CROPS

摘要

A method for producing ethanol from root and tuber crops comprises the following steps of: (a) removing skin of root and tuber crops by using a peeling device which comprises a pedestal, a roller rotatablely fitted on the pedestal and having a feed inlet and a material discharge hole, a spiral feeder located within the roller and fixedly connected with the inner wall of the roller, and a driving device, wherein raw material of root and tuber crops is fed into the roller via the feed inlet, and the driving device drives the roller and the spiral feeder to rotate together; (b) pulverizing the peeled material obtained in step (a); (c) mixing the pulverized material obtained in step (b) with enzyme, and subjecting the mixture to enzymolysis; and (d) fermenting the enzymolysis product obtained in step (c). The method can improve ethanol yield.
