Abstract

The invention relates to a preparation method of fuel alcohol by fermenting waste potato dregs, which comprises the following steps: obtaining waste potato dregs, smashing, dipping, boiling, saccharifying, fermenting, distilling and measuring an alcohol degree. The invention has simple process and convenient processing, and the waste potato dregs are fermented into the alcohol, thereby reducing the environmental pollution, changing waste into valuable and saving the preparation cost.

Description

technical field [0001] The invention belongs to a preparation method of fuel alcohol, in particular to a preparation method of potato waste residue fermented fuel alcohol. Background technique [0002] Potatoes, as a traditional crop, are widely grown in my country. The processing of potatoes in the north is mainly to extract starch, make vermicelli, vermicelli, etc., resulting in a large amount of potato dregs. The water content of fresh potato dregs is as high as 80%, and there are as many as 33 kinds of bacteria. It is not easy to store and transport. After spoilage, it will produce stench and cause environmental pollution. With the development of potato industrialization in my country, more and more attention has been paid to the disposal of waste residues caused by potato starch processing. At present, the utilization of potato waste residue in my country mainly includes: microbial fermented feed, extraction of dietary fiber, extraction of pectin, etc., but the use of...
