Title:
LIQUID CONCENTRATION SYSTEM AND RICE WINE CONCENTRATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/177072
Kind Code:
A1
Abstract:
Provided is a liquid concentration system and a rice wine concentration system that can increase the concentration of liquids such as rice wine, cosmetics, perfumes and the like, whilst suppressing oxidation. This liquid concentration system 1 comprises at least: a base material tank 10 that stores a liquid; a reverse osmosis membrane 30; and a pressure-application means 100 for pressure-feeding the liquid within the base material tank to the reverse osmosis membrane. The pressure-application means is composed of: a cylinder 21; a piston 22 reciprocating in an inner part of the cylinder; and a compressed gas supply device 23 that feeds a compressed gas to the inner part of the cylinder and thereby causes the piston to move. By using the cylinder and the piston as the pressure-application means to pressure-feed a rice wine to the reverse osmosis membrane, the present invention achieves an effect in which the oxidation of the rice wine is suppressed in comparison to conventional cases in which a high-pressure pump is used.
