Production process for continuously distilling ethanol by continuous fermentation of sweet sorghum stalks

Abstract

Disclosed is a continuous fermentation and continuous distillation production process for producing ethanol by fermenting straws and stalks such as sugarcanes, sweet sorghum stalks, cornstalks and straws by dry method as well as a product line. The process mainly adopts facilities of a continuous fermentation tower and a continuous distillation tunnel. The process and the product line overcome the defects of intermittent production, incomplete material steaming, low product yield, complex charging and discharging operations and disordered field of the traditional process. The process and the product line have the advantages of continuous production, high degree of automation, even mixing of materials, proper fermentation, complete distillation and high product yield. The process is a novel process with innovation significance.

Description

Technical field

[0001] The invention belongs to the production line design and equipment matching technology of ethanol production by fermenting and distilling straw-like solid matter by dry method (slightly adding water or adding less water), which is suitable for modern large-scale production requirements, and makes the production process continuous, with high degree of automation and high product yield , Stable texture, energy saving and consumption reduction. Background technique

[0002] The production of ethanol by fermentation and distillation of sugarcane, sweet sorghum stalks, corn stalks, wheat stalks and other straws is a new biomass energy technology. In the past, the production process was basically the same as the traditional wine making process, which was carried out manually by using traditional wine making equipment. Fermentation and distillation work in the production process are completed using a kind of equipment and facilities, the main equipment and fa...
