Method for producing alcohol by utilization of canna edulis ker and plant straws

Abstract

The invention provides a method for producing alcohol by utilization of canna edulis ker and plant straws and belongs to the alcohol production field. After canna edulis ker and plant straws are cleaned and screened, canna edulis ker and plant straws are crushed respectively. The plant straws are crushed to 40-60 meshes by a pulverizer. The crushed canna edulis ker is subjected to dehydration or water addition, and thus the water content of the processed canna edulis ker is between 13%-17%. The crushed plant straws are mixed with canna edulis ker. Raw materials saccharifying enzyme and white sugar are added and the mixture is fermented for 5-7 days at a temperature of 25 DEG C-45 DEG C. The mixture after fermentation goes into a distillation machine for distillation and goes into a cooling machine for cooling in order. Alcohol obtained after cooling is purified, and the finished product alcohol is obtained finally. The problems are solved that crushed canna edulis ker cannot be fermented fully because of small gaps, thus the alcohol conversion rate is low, the raw material utilization rate is low, and the production cost is raised greatly during the production process in a present method for producing alcohol with canna edulis ker as a raw material.

Description

technical field [0001] The invention relates to a method for producing alcohol from plantain taro and plant stalks, and belongs to the field of alcohol production. Background technique [0002] Canna edulis ker (Canna edulis ker) is a starch crop with great potential. It can be grown in mountains and lowlands. Canna edulis ker is also known as dry lotus root, banana root, and ginger taro. Canna taro has become a new raw material source of high-value starch in Asia, and is also a good raw material for brewing and fermentation, food and feed processing. It is widely planted in Guizhou, Yunnan and Guangxi in the western region. [0003] At the present stage, the method of producing alcohol with plantain taro as raw material has become popular in Southwest China, but the existing methods are to dry and crush plantain taro or plantain taro and directly carry out fermentation and other processes. The crushed plantain taro has a small gap , it is difficult to fully ferment, so tha...

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for producing alcohol by using plantain taro and plant stalks, so as to solve the problem that in the existing method of producing alcohol using plantain taro as raw material, it is difficult to fully ferment the crushed plantain taro due to the small gap. The conversion rate of alcohol in the production process is low, and the utilization rate of raw materials is low, which greatly increases the problem of production cost
