Embodiment 1

[0088] Using cassava as raw material to produce super edible brewing alcohol products that meet GB 18350-2013, the production process mainly includes liquefaction unit, fermentation unit, rectification and waste liquid treatment unit, see for example figure 1 , figure 2 , image 3 , Figure 4 . Specific steps are as follows:

[0089] 1. Liquefaction unit

[0090] First, the cassava raw material is sent to a pulverizer for crushing, and the pulverized powder is sent to a mixer, and the mixer simultaneously adds mixing water. The mixing water in the process water tank is heated by the mixing water heater and then sent to the mixing device, and auxiliary materials such as liquefied enzyme and ammonia water are added. The hot side material of the mixing water heater is liquefied mash, which is obtained by the mixing device The powder slurry is sent into the mixing tank, and the temperature of the mixing material is greater than 72°C.

[0091]The powder slurry obtained from ...

Embodiment 2

[0110] Using corn as raw material to produce special-grade edible brewing alcohol products that meet GB 18350-2013, the production process mainly includes liquefaction unit, fermentation unit, rectification and waste liquid treatment unit, see for example figure 1 , figure 2 , image 3 , Figure 4 . Specific steps are as follows:

[0111] 1. Liquefaction unit

[0112] Firstly, the corn raw material is sent to the grinder for crushing, and the crushed powder is sent to the mixer, and the mixer is added with mixing water at the same time. The mixing water in the process water tank is heated by the mixing water heater and then sent to the mixing device, and auxiliary materials such as liquefied enzyme and ammonia water are added. The hot side material of the mixing water heater is liquefied mash, which is obtained by the mixing device The powder slurry is sent into the mixing tank, and the temperature of the mixing material is 85°C.

[0113] The powder slurry obtained from...

Embodiment 3

[0132] Using corn as raw material to produce special-grade edible brewing alcohol products that meet GB 18350-2013, the production process mainly includes liquefaction unit, fermentation unit, rectification and waste liquid treatment unit, see for example figure 1 , figure 2 , image 3 , Figure 4 The body steps are as follows:

[0133] 1. Liquefaction unit

[0134] First, raw materials such as corn, wheat, sorghum, rice, cassava and sweet potato are sent to the grinder for crushing, and the crushed powder is sent to the mixer, and the mixer is added with mixing water at the same time, and the mixing water comes from the process water tank. The process water tank includes the evaporation condensate from the multi-effect evaporation unit, the washing water from the carbon dioxide scrubber, and the rectification wastewater from the alcohol refining unit.

[0135] The mixing water in the process water tank is heated by the mixing water heater and then sent to the mixing devi...

Abstract

The invention discloses a brewing alcohol production method. The brewing alcohol production method mainly involves a liquefying unit, a fermenting unit and a rectifying and waste liquor treating unitand includes cross-gelatinization-point pulping, multiple-effect utilization of low-energy-level steam, non-condensable gas impurity removal of low-alcohol liquefied mash and recycling of process wastewater. An annular feeding pipe is used for a fermenting tank of the fermenting unit, bidirectional alternate feeding with sequential control is adopted, and the pipe is free from a fermented mash feeding lag deposit area, so that abnormal fermentation is inhibited. The brewing alcohol production method solves the industrial problems of alcohol product instability, high energy consumption, the requirement on redistillation and failure to reach the superfine edible alcohol standards of GB 18350-2013 in taste index of a mainstream brewing alcohol production technology, thereby meeting the development requirement of the liquid-base Baijiu industry. Brewing alcohol obtained by the brewing alcohol production method is 14-18% in alcohol content of mature mash, the alcohol yield of starch is notless than 92%, and zero wastewater discharge in a main production process is achieved through recycling of evaporation condensation water.

Description

technical field [0001] The invention relates to a production method of brewing alcohol, which discloses pulping across the gelatinization point, multi-effect utilization of low-energy steam, removal of impurities by non-condensable gas in liquefied mash with low alcohol content, circular bidirectional rotation program feeding of fermented mash, and recycling of process wastewater. Use other technical solutions to solve the current mainstream production process of brewing alcohol, such as the instability of alcohol products, high energy consumption, especially the difficulty in reaching the GB 18350-2013 super edible alcohol standard for taste indicators, and the need for re-steaming treatment, etc., to further effectively reduce the production of brewing alcohol The energy and material consumption of the process improves the quality and market competitiveness of brewed alcohol products, and meets the needs of the development of the liquid-based liquor industry. It belongs to th...
