Embodiment 1

[0036] Corn is used as raw material to produce fuel ethanol products. The production process mainly includes liquefaction unit, fermentation unit, rectification and dehydration unit, etc. Specific steps are as follows:

[0037] 1. Liquefaction unit

[0038] For the production process of the liquefaction unit, see figure 1 - Flow chart of liquefaction unit. Firstly, the dry corn 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 115°C, and then sent to the maintenance tank for 25 minutes. , the material enters the liquefied mash fla...

Embodiment 2

[0047] Cassava 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:

[0048] 1. Liquefaction unit

[0049] 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 110°C, and it is sent to the maintenance tank for 8 minutes. , the material enters the liquefie...

Abstract

The invention relates to a combined production method for fuel alcohol and edible alcohol. Fermented mash mature enters a rough distillation column, crude alcohol distilled from the top of the column is fed into a rectification column (2), liquid alcohol distilled from the side of the column is fed into 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 objects distilled from the top of the rectification column (1) are made into fuel alcohol under the adsorption effect of dehydrators on amolecular sieve. In the production process of edible alcohol, objects distilled from the top of the rectification column (1) are fed into an aldehyde disengagement column, objects distilled from the top of the rectification column (2) and partial objects distilled from a boiler of the column are also fed into the aldehyde disengagement column, liquid alcohol distilled from a boiler of the aldehyde disengagement column is fed into a product column, and thus, qualified edible alcohol is distilled from the upper side of the product column. The invention realizes multiple varieties of alcohol products on the same device, effectively decreases consumption in materials and energy in the production process of the fuel alcohol and the edible alcohol, reduces the investment on device, and improvesthe market competitiveness of the fuel alcohol and the edible alcohol.

Description

technical field [0001] The invention relates to a combined production method 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 consumption. Market competitiveness of ethanol and 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 produ...
