Abstract

The invention discloses a method for extracting industrial ethanol from Canna edulis ker leftovers. The method comprises the following steps: crushing the Canna edulis ker leftovers to obtain Canna edulis ker powder; crushing straw to obtain straw powder; weighing, by weight, 60 to 70 parts of the Canna edulis ker powder and 20 to 30 parts of the straw powder, carrying out uniform mixing under stirring, and adding glucoamylase for fermentation so as to obtain a fermentation product A; weighing, by weight, 1 to 3 parts of yeast for cooked materials, 3 to 6 parts of potato starch, 4 to 6 parts of semi-finished sweet wormwood crystals and 2 to 3 parts of inorganic nitrogen, carrying out mixing under stirring, and then performing fermentation to obtain a fermentation product B; and mixing thefermentation product A with the fermentation product B according to a weight ratio of 7: 3, allowing the mixture to enter distillation machine, adding 1 to 3 parts of Chinese yew leaf powder at the same time, and allowing a distillation product to pass through a rectifying tower so as to obtain industrial ethanol. The method of the invention can realize effective recycling of the Canna edulis kerleftovers, prepares the industrial ethanol with high added value from the Canna edulis ker leftovers, and has good economic benefits.

Description

technical field [0001] The invention relates to a method for extracting industrial ethanol by using leftovers of plantain taro, belonging to the technical field of industrial ethanol preparation. Background technique [0002] Canna taro, also known as dry lotus root, banana root, and ginger taro, is a plant of the genus Canna in the banana family. Good ingredients for processing. Canna taro starch has a large particle size, low gelatinization temperature, good paste transparency, high chain starch content, good film-forming properties, and a large molecular weight, which is close to potato starch, and has good application properties. The development and utilization of plantain taro is mainly to produce starch, and to develop starch deep-processing products and food items such as vermicelli and vermicelli. When producing starch or other products from plantain taro, waste leftovers will be generated, and these leftovers have not been effectively treated at present. It is not...
