Brewing device by taking sweet sorghum stalks as raw materials

Abstract

The invention relates to the field of preparation of alcohol from sweet sorghum stalks, in particular to a brewing device by taking the sweet sorghum stalks as raw materials. According to the brewing device, the problems of more dust, difficulty in degerming, incapable of realizing continuous production, long fermentation time, low alcohol yield by crushing and conveying raw materials in open airin the prior art are solved. The sweet sorghum stalks are fed into a crushing machine through a raw material conveyor, are crushed and then are fed into a sterilizing and collecting tank through an airtight pipeline; the sterilized materials are fed into the conveyor and are simultaneously inoculated by an inoculated spraying pipe; the materials are mixed with bacteria and stirred and then are fed into a rotary drum type solid state fermentation tank in a closed form for fermenting; the fermented materials are fed into an alcohol distiller for continuously distilling in a closed form; and steam containing alcohol enters a cooling tower for separating. The brewing device has the advantages that the fermenting time is short, various indexes are easily controlled, the mixing degree is of thestrain is uniform and the fermenting materials are balanced in fermentation; the pollution to the environment is avoided, so that the fermentation is cleaner; and the quality of products is improved,continuous operation can be ensured and the production efficiency is improved.

Description

technical field [0001] The invention relates to a device for producing alcohol or wine by using agricultural by-products, in particular to a device for producing alcohol or wine by using sweet sorghum stalks as raw materials. Background technique [0002] The method of using sweet sorghum to ferment alcohol in the prior art is mainly composed of liquid fermentation technology and solid state fermentation technology. The liquid fermentation technology is because the juice in the sweet sorghum stalk is extracted first, and the juice is used for liquid fermentation. There will be a lot of sugar loss during the juicing process, and the process is complicated and the cost is high. However, the existing solid-state fermentation technology is to inoculate first, then ferment in a fermentation tank, and then put the fermentation material into a still still for distillation to obtain an ethanol product. In the above process, the sweet sorghum stalks need to be crushed and transporte...
