SYSTEM AND METHOD FOR SIMULTANEOUSLY PREPARING ALCOHOL-FREE WINE AND HIGH-ALCOHOL LIQUOR

摘要

A system for simultaneously preparing alcohol-free wine and higli-alcohol liquor, comprising a primaiy membrane separation system and a secondaty membrane separation system. An inlet of the primaiy membrane separation system is connected to raw materials, and a pemieation side of the primaiy membrane separation system is coimected to an inlet of the secondaiy membrane separation system: both the primaiy membrane separation system and the secondary membrane separation system comprise an organic-permselective pervaporation membrane. The method for simultaneously preparing the alcohol-free wine and the high-alcohol liquor comprise the following steps: feeding the wine produced by femientation into the primaiy membrane separation system, ethanol and aromatic substances therein permeating the membrane in a vapor form to form a primary permeating fluid with alcohol content of 28-32°. and a primaiy residual permeating fluid being the alcohol-free wine with alcohol content of less than 0.5°: the primaiy permeating fluid entering the secondary membrane separation system, the ethanol and the aromatic substances therein permeating the membrane in the vapor form to form a secondaiy permeating fluid, and the secondaiy permeating fluid being the concentrated high-alcohol liquor.
