Embodiment 1

[0021] Embodiment 1: a kind of method for the full recycling of yellow water is carried out as follows:

[0022] Such as figure 1 As shown, the wine brewing by-product yellow water is injected into the raw material tank 1 at a temperature of 40°C, the discharge valve 2 is opened, and the high-pressure feed pump 3 is used to transport the yellow water in the raw material tank 1 to the porous separation membrane at a flow rate of 0.8 m / s In system 4, the absolute pressure of the high-pressure pump is 200 kPa in contact with the outer pressure membrane made of ceramic material, and the pressure difference is used as the driving force to perform membrane separation based on physical sieving. Porous separation membrane, the yellow water clear liquid that passes through the porous separation membrane enters the buffer tank 5, and the retentate A is obtained from the intercepted side, mainly sugars, amino acids, residues, humus, yeast autolysates, microbial cells and living cells et...

Embodiment 2

[0025] Embodiment 2: a kind of method for the full recycling of yellow water is carried out as follows:

[0026] Such as figure 1As shown, the wine brewing by-product yellow water is injected into the raw material tank 1 at a temperature of 35°C, the discharge valve 2 is opened, and the high-pressure feed pump 3 is used to transport the yellow water in the raw material tank 1 to the porous separation membrane at a flow rate of 1.5 m / s In system 4, it is in contact with the outer pressure membrane made of ceramic material, and the absolute pressure of the high-pressure pump is 350 kPa, and the pressure difference is used as the driving force to perform membrane separation based on physical sieving. Porous separation membrane, the yellow water clear liquid that passes through the porous separation membrane enters the buffer tank 5, and the retentate A is obtained from the intercepted side, mainly sugars, amino acids, residues, humus, yeast autolysates, microbial cells and living...

Embodiment 3

[0029] Embodiment 3: a kind of method for the full recycling of yellow water is carried out as follows:

[0030] Such as figure 1 As shown, the wine brewing by-product yellow water is injected into the raw material tank 1 at a temperature of 25°C, the discharge valve 2 is opened, and the high-pressure feed pump 3 is used to transport the yellow water in the raw material tank 1 to the porous separation membrane at a flow rate of 2 m / s In system 4, it is in contact with the outer pressure membrane made of ceramic material, and the absolute pressure of the high-pressure pump is 500 kPa, and the pressure difference is used as the driving force to perform membrane separation based on physical sieving. Porous separation membrane, the yellow water clear liquid that passes through the porous separation membrane enters the buffer tank 5, and the retentate A is obtained from the intercepted side, mainly sugars, amino acids, residues, humus, yeast autolysates, microbial cells and living ...

Abstract

The invention discloses a method for fully recycling yellow water in a white spirit production process. The method comprises the following steps: firstly, separating yellow water in a raw material tank by virtue of a porous separating membrane system; feeding yellow water clean liquor permeating a porous separating membrane into a pervaporation membrane for further separation; enriching most alcohol, aldehyde and ester matters through the pervaporation membrane on the other side of the membrane in the form of gas state; recovering the matters which are condensed by using a condenser of a pervaporation membrane system to a product storage tank for blending white spirit; increasing fragrant component and the like in original spirit; and further recovering intercepted porous separating membrane permeating liquor and pervaporation membrane permeating liquor. The method disclosed by the invention has the remarkable characteristic that the yellow water recovery efficiency is improved by virtue of two membrane separating and integrating methods including the porous separating membrane and the pervaporation membrane, so that the effective matters of the yellow water are utilized to a maximum extent, thereby thoroughly solving the outlet problem of the yellow water. In addition, the method further has the advantages of being simple in equipment and low in separating energy consumption and has strong practicality.

Description

technical field [0001] The invention relates to a method for fully recycling yellow water in the liquor production process, and belongs to the technical field of liquor making. Background technique [0002] Yellow water is a by-product at the bottom of the cellar during the fermentation of traditional Luzhou-flavor liquor. It is a yellow-brown viscous liquid with a sour and astringent taste. Yellow water contains more active ingredients and has extremely high utilization value. Yellow water contains alcohols, acids, aldehydes, esters and other substances that are particularly rich in aroma and taste. In addition, it also contains beneficial microorganisms, sugar substances, nitrogenous compounds and A small amount of tannins, pigments and aroma precursors, etc. The amount of yellow water produced by wineries across the country is huge every year, and most of the wineries have not used it effectively and directly discarded it. Because the yellow water has the characteristic...
