Problems solved by technology

[0003] At present, the domestic production of alcohol from potato raw materials mainly adopts liquid fermentation technology. The disadvantage of this process is mainly that the production process consumes a lot of water, resulting in a large amount of distiller's grains (generally, every ton of alcohol produced will produce more than 15 tons of distiller's grains) distiller's grain liquid), and the distiller's grain processing difficulty of potato raw material is the main factor that restricts the production and development of starchy potato raw material alcohol; the clear liquid alcoholic fermentation technology developed on the basis of liquid alcoholic fermentation, mainly through the introduction of foreign technical equipment, There are disadvantages such as huge investment in equipment, high operating costs, and high cost of a

Embodiment Construction

[0014] Embodiment Take 100kg of fresh plantain taro tubers, slice them and dry them naturally, so that the mass fraction of water is controlled at 13% to 18%, and the mass fraction of starch is controlled at 60% to 63%; About 20kg of canna raw material powder with a density of 1-3mm; add 60kg of water into the cooking container, then add the canna raw material powder while stirring until the slurry is uniform, and at the same time add α-amylase at a ratio of 3u / g raw material , stir evenly, and start cooking; when the temperature of the cooked material reaches 95-100°C, add the remaining 2 / 3 α-amylase at a ratio of 6u / g raw material, continue to liquefy for 60 minutes, and end the liquefaction operation; Lower it to 60°C, and at the same time use 0.5mol / L sulfuric acid solution to adjust the pH of the feed solution to 4.2-4.5, and add the glucoamylase diluted with 6 times of water in the proportion of 150u / g raw material; when the feed liquid temperature drops to 30 At ~33°C, ...

Abstract

A process for preparing alcohol from dried Japanese banana slices includes pulverizing, stirring, adding amylase, digestion, coolying, adding beta-amylase, saccharifying, inoculating yeast, fermenting and distilling.

Description

technical field [0001] The invention relates to a method for preparing ethanol, in particular to a method for preparing ethanol by distilling a fermented solution, specifically, it belongs to a method for producing ethanol by using dried plantain taro slices as raw materials. Background technique [0002] Canna edulis Ker, whose scientific name is Canna edulis Ker, belongs to the perennial herbaceous plant of Cannaaceae (Cannaeeae). Fiber 2.65%, fat 0.257%, protein 3.63%, tannin 0.19%, widely planted in Guizhou Province, Yunnan Province and Guangxi Autonomous Region in the western region. [0003] At present, the domestic production of alcohol from potato raw materials mainly adopts liquid fermentation technology. The disadvantage of this process is mainly that the production process consumes a lot of water, resulting in a large amount of distiller's grains (generally, every ton of alcohol produced will produce more than 15 tons of distiller's grains) distiller's grain liqu...
