Embodiment 1

[0038] Cassava stems are used as raw materials to produce fuel ethanol products. The production process mainly includes liquefaction unit, fermentation unit, rectification and dehydration unit, etc. Specific steps are as follows:

[0039] 1. Liquefaction unit

[0040] For the production process of the liquefaction unit, see figure 1 - Flow chart of liquefaction unit. Firstly, the dried cassava raw material is cleaned and removed, and then crushed. The crushed raw materials are added with water in the mixer to make a slurry and sent to the slurry tank, and amylase and other auxiliary materials are added at the same time. In the slurry tank, the slurry is pumped to the jet liquefier with a slurry pump. The jet liquefier controls the heating temperature of the material by controlling the amount of water vapor. The temperature of the material at the outlet of the injector is controlled to 120°C, and it is sent to the maintenance tank for 20 minutes. , the material enters the l...

Embodiment 2

[0050] Corn is used as raw material to produce edible alcohol products. The production process mainly includes liquefaction unit, fermentation unit, rectification and dehydration unit, etc. Specific steps are as follows:

[0051] 1. Liquefaction unit

[0052] For the production process of the liquefaction unit, see figure 1 - Flow chart of liquefaction unit. Firstly, the dried cassava raw material is cleaned and removed, and then crushed. The crushed raw materials are added with water in the mixer to make a slurry and sent to the slurry tank, and amylase and other auxiliary materials are added at the same time.

Abstract

The invention relates to a composite process of fuel alcohol and edible alcohol. In the production process of alcohol products, fermented mash mature in a self-fermentation unit enters a rough distillation column, crude alcohol distilled from the top of the rough distillation column is fed into a rectification column (2), liquid alcohol distilled from the side of the rough distillation column column is fed into a feed inlet of a rectification column (1), vapor phase objects distilled from the top of the rectification column (1) are fed into a molecular sieve absorption column, and thus, fuel alcohol is obtained. In the production process of edible alcohol products, objects distilled from the top of the rough distillation column and the top of the rectification column (1) and partial objects distilled from the boiler of the rectification column (2) are all fed into an aldehyde disengagement column, liquid alcohol distilled from the boiler of the aldehyde disengagement column is fed into the rectification column, and then, the liquid alcohol is distilled from the top of the column and fed into a reclaiming column as feed; the liquid alcohol is distilled from the side of the upper part of the rectification column (2) and fed into the feed inlet of a rectification column (3) , and qualified edible alcohol is distilled from the boiler of the rectification column (3). The invention realizes multiple varieties of alcohol products on the same device, effectively decreases consumption in materials and energy in the production process of fuel alcohol and edible alcohol, reduces the investment on device, and improves the market competitiveness of the fuel alcohol and the edible alcohol.

Description

technical field [0001] The invention relates to a compound process of fuel ethanol and edible alcohol, which can realize multiple varieties and specifications of alcohol products on the same alcohol device, effectively reduce material consumption and energy consumption in the production process of fuel ethanol and edible alcohol, reduce device investment, and increase fuel ethanol production. and the market competitiveness of edible alcohol. Background technique [0002] Fermented alcohol is a renewable and important basic raw material and product. According to different functions and purity requirements, it is divided into edible alcohol and fuel ethanol products. Fuel ethanol products are mainly used as fuels and raw materials for chemical production; edible alcohol products are mainly used for brewing beverages and raw materials for chemical production. [0003] Fuel ethanol produced by fermentation has similar combustion properties to fossil fuels, and its production r...
