Example Embodiment

[0087] Example 1:

[0088] Use cassava as raw material to produce special-grade edible brewed alcohol products that meet GB 18350-2013. The production process mainly includes liquefaction unit, fermentation unit, rectification and waste liquid treatment unit, see eg 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 the pulverizer for pulverization, and the pulverized powder is sent to the mixer, and the mixer is added with mixing water at the same time. The mixing water of 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 slurry is sent to the mixing tank, and the mixing temperature is greater than 72°C.

[0109] Example 2:

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

[0111] 1. Liquefaction unit

[0112] First, the corn raw materials are sent to the pulverizer for pulverization, and the pulverized powder is sent to the mixer, and the mixer adds the mixing water at the same time. The mixing water of 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 to the mixing tank, and the mixing temperature is 85°C.

[0131] Example 3:

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

[0133] 1. Liquefaction unit

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

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

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...
