Problems solved by technology

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

Embodiment Construction

[0022] 1. Straw crushing: When the corn ears are waxy in the late stage, the straws are still green and the moisture content is above 60%, the corn ears are harvested, and then the harvested straws are pulled to the winery by car, and the leaves and tips are removed by a straw crusher. The corn stalks were crushed and crushed into 1 cm stalk slag.

[0023] 2. Prepare distiller's mother: first prepare water with a sugar content of 3% and a water temperature of 35°C, then add Angel yeast, the ratio of yeast to water is 50:1 (percentage by weight), stir and place for 30 minutes.

[0024] 3. Mixing material: Stir the distiller's mother solution and the crushed stalk residue, and weigh them.

[0025] 4. Fermentation in the tank: put the stirred stalk material into the fermentation tank, the volume of the fermentation tank is 2 cubic meters, and 1 ton of the stalk material is loaded. The temperature of the material entering the pool is 15°C. After 3-4 days, the material temperatur...

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...
