1. A method for simultaneously preparing alcohol-free wine and high-alcohol liquor, comprising the following steps:
using a wine produced by fermentation as a feed, wherein a temperature of the feed is 35-45° C.; first, feeding the feed into a primary membrane separation system, wherein a pressure on a permeate side of the primary membrane separation system is maintained at 5-10 kPa, ethanol and aromatic substances therein permeate the membrane in a vapor form to form a primary permeate with alcohol content of 28-32°, and a primary retentate is the alcohol-free wine with alcohol content of less than 0.5°; and
making the primary permeate enter a secondary membrane separation system at 35-45°° C., wherein a pressure on a permeate side of the secondary membrane separation system is 5-10 kPa, ethanol and aromatic substances therein permeate the membrane in a vapor form to form a secondary permeate, and the secondary permeate is the concentrated high-alcohol liquor,
wherein
both the primary membrane separation system and the secondary membrane separation system comprise an organic-permselective pervaporation membrane,
the organic-permselective pervaporation membrane consists of a basement membrane and a separation layer, a material of the basement membrane is sulfonated poly (aryl ether ketone) selected from sulfonated polyether ketone and sulfonated polyether ketone ether ketone ketone, and a pore size of the basement membrane is 5 nm-80 nm,
a material of the separation layer comprises hydrophobic nano titanium dioxide and amino-terminated modified polydimethylsiloxane, an ammonia value of the amino-terminated polydimethylsiloxane is 0.2-0.8.
