Technique for producing ethanol with corn stalk

Abstract

The invention relates to a manufacturing method, belonging to processing field of farm and sideline products. The invention can produce primary product of ethanol by crushing and steaming the corn straw, and then fermenting in a pool after adding angel yeast and distilling, and then can produce absolute alcohol: ethanol by further processing of alcohol plant. The invention provides a new road forcountry waste, and has the advantages of recycling the waste into valuable, increasing the income of peasant and saving the foodstuff. About three tons of foodstuffs can be saved when producing one ton ethanol, and the dreg after producing can be used as fodder or making paper and fiber plate.

Description

technical field [0001] The invention belongs to the field of agricultural by-product processing. Background technique [0002] Corn stalks are an important by-product of crops, a production resource for industrial and agricultural production, and a resource for renewable energy. As a large agricultural country in my country, the total annual output of corn stalks can reach hundreds of millions of tons. However, in recent years, the output of corn stalks in my country has increased rapidly with the continuous improvement of the unit output of major grain products, and the traditional straw utilization methods have gradually been weakened and eliminated. Some farmers have adopted the simplest way to deal with the prominent problems in production - burning or dumping randomly, which not only wastes precious resources, but also causes a lot of social, economic and social damage such as air pollution, soil mineralization, fires and traffic accidents. Ecological issues have become...

However, in recent years, the output of corn stalks in my country has increased rapidly with the continuous improvement of the unit output of major grain products, and the traditional straw utilization methods have gradually been weakened and eliminated. Some farmers have adopted the simplest way to deal with the prominent problems in production - burning or dumping randomly, which not only wastes precious resources, but also causes a lot of social, economic and social damage such as air pollution, soil mineralization, fires and traffic accidents. Ecological issues have become hot and difficult points of government concern, social concern, and public opinion concern

[0003] According to measurements, the sugar content (brix bx%) in corn stalk juice reaches 8%-14%. Because the sugar content is not as good as sweet sorghum, sugar cane, sugar beet and other sugar crops, it can only be directly used as feed
