Method for producing alcohol by using dry plate of banana dasheen as raw material

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...

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 alcohol production, and the utilization rate of distiller's grains is low

Chinese patent No. 88103430 " the new method of fresh canna taro production alcohol " discloses the new raw material of alcohol production, but on the one hand owing to the fresh canna taro (tuber) acquisition quality standard of no standard, fresh canna taro (tuber) can't be carried out effectively Preservation and storage; on the other hand, in the process of producing alcohol, the pretreatment of fresh plantain taro needs to be adjusted for acidity, which requires a certain amount of sulfuric acid, which puts forward higher requirements for the production equipment and the material of the tank, and also increases The cost of alcohol production

Therefore, it is also difficult to realize industrialization with fresh plantain taro as raw material to produce alcohol
