Abstract
A system for simultaneously preparing alcohol-free wine and high-alcohol liquor, comprising a primary membrane separation system and a secondary membrane separation system. An inlet of the primary membrane separation system is connected to raw materials, and a permeation side of the primary membrane separation system is connected to an inlet of the secondary membrane separation system; both the primary membrane separation system and the secondary membrane separation system comprise an organic matter preferentially-permeable 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 fermentation into the primary 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 primary residual permeating fluid being the alcohol-free wine with alcohol content of less than 0.5°.
