Embodiment Construction

[0017] 1. Separate the bran from wheat flour;

[0018] 2. Add water to wheat flour to separate gluten powder, further dry and pulverize to obtain finished gluten powder;

[0019] 3. Liquefy and saccharify the suspension after the gluten is separated, and then use double-circulation gas to stir the anaerobic fermentation tank while separating and fermenting;

[0020] 4. The fermented mash produces 95% hydrous alcohol through rectification, and the alcohol is further dehydrated through an adsorption tower equipped with an adsorbent for dehydration of hydrous ethanol to obtain anhydrous alcohol;

[0021] 5. The bottom of the crude distillation tower is concentrated and dried to obtain feed.

[0022] 6. The remaining distilled water and concentrated condensed water of the rectification tower are aerobically treated to make the COD reach 80mg / l, and then return to the ingredients to form a closed loop of water.

[0023] After liquefaction and saccharification of the suspension, t...

Abstract

A clean process for preparing alcohol from wheat includes such steps as grinding, separating bran, adding water to wheat flour, separating out gluten powder, liquefying the suspension of residual starch, saccharifying, fermenting, rectifying to obtain 95% alcohol, dewatering to obtain absolute alcohol, concentrating and drying residue to obtain feed, aerobically treating the residual water and condensed water for reuse.

Description

Technical field [0001] The invention relates to an alcohol production technology, which is a clean method alcohol production technology that fully utilizes raw materials comprehensively, increases product added value, increases income, and reduces production costs, and belongs to the fields of alcohol, environmental protection and the like. Background technique [0002] At present, the production of fermented alcohol at home and abroad mostly uses corn and dried potatoes as raw materials, especially corn as raw materials. When corn is used as raw material, it can be divided into two types: dry method and wet method. In the United States, the wet method is mainly used, with large equipment investment and complicated processing process; in Europe, the dry method is mainly used, and the processing process is simple. After the corn is crushed (degermed or without degerming), carry out liquefaction, saccharification and fermentation, and this method has 12 to 15 tons of distillat...
