Embodiment 3

[0062] The present invention is applied in a membrane distillation method of the base wine of Fengxiang type liquor that has been upgraded through membrane distillation, and the process steps are as follows:

[0063] A. Raw wine pretreatment

[0064] Take the original wine of Fengxiang type baijiu with the same alcohol content; or mix the original wine of Fengxiang type baijiu with different alcohol content;

[0065] B. Original wine film distillation treatment

[0066] Heating the pretreated original wine to the vaporized state on one side of the membrane, the membrane is a hydrophobic hollow fiber membrane, plate membrane or roll membrane, and controlling the vacuum degree to 0.7-0.95MPa on the other side of the membrane, Make the original wine heated to the vaporized state migrate from one side of the membrane to the other side for transmembrane migration;

[0067] C. Gas condensation

[0068] In step B, the original wine heated to the vaporized state migrates across the...

Abstract

The invention discloses a membrane distillation apparatus used for improving base liquor quality. The membrane distillation apparatus used for improving base liquor quality comprises a membrane distiller, a condenser and a liquid collection tank. One end of the condenser is communicated with the output end of the membrane distiller, and the other end of the condenser is communicated with the input end of the liquid collection tank. A plurality of sets of U-shaped hollow fiber membranes are arranged in the membrane distiller, the hollow fiber membranes are soaked in base liquor in the membrane distiller, and the opening ends of the U-shaped hollow fiber membranes are communicated with a gas outlet in the top of the membrane distiller. The membrane distillation apparatus used for improving base liquor quality has the advantages of distillation purification and membrane selective interception and separation, and effectively retains beneficial substances in the base liquor, the solution does not need to be heated to the boiling point, waste heat and cheap energy such as warm industrial waste water of factories can be utilized, thus, energy is saved, separation efficiency is high, membrane flux is large, quality improving efficiency is high, selective replacing or maintenance can be achieved, the sealing performance of a sealing cavity is high, and gas overflow can be effectively avoided.

Description

technical field [0001] The invention relates to a raw wine device, in particular to a membrane distillation device for improving the quality of raw wine. Background technique [0002] At present, membrane separation technology is a separation technology widely used in the separation, concentration and purification of solutions or gaseous substances. The membrane wall is densely covered with micropores, the stock solution passes through one side of the membrane under a certain pressure, the solvent and small molecular solutes pass through the membrane wall to become the filtrate, and the macromolecular solutes are retained by the membrane to achieve the purpose of material separation and concentration. The membrane separation process is a dynamic filtration process. The macromolecular solute is blocked by the membrane wall and flows out with the concentrated solution. The membrane is not easy to be blocked and can be used continuously for a long time. The filtration process...
