JS-WSU-M2 series products are specially designed to meet the brewing needs of wineries. This wine separationand extraction system is different on the traditional pot distillation and extraction method. By using our unique wine membrane，the wine can be perfectly separated into brandy and alcohol-free wine without any waste liquid production,increase production, and significantly reduce energy consumption，and the brandy extracted by this system,with thorough removal of impurities, pure taste and natural fragrance.

Lower energy consumption, more compact footprint,better process control，no waste liquid production and substantial increase inproduction capacity enable wineries of all sizes to further reduce operating costs while maintaining absolute respect for the quality characteristics of brandy.

Our Js-WSU-M2 series products adopt a new extraction processdifferent from the traditional brandy brewing process，whichmakes the winery achieve lower energy consumption, better outputand zero waste liquid production while ensuring the quality ofbrandy.

The process characteristics of this series of products include:

Conventional membranes including organic membranes and inorganic membrafor separation of small molecules with size lesss than 1 nm. remain challenge in achieving high separation performance and scalable fabrication. To overcome this challenge. Prof. Wanqin Jin research group at Nanjing Tech University proposed a new kind of membrane; organic-inorganc composite membrane. With precisely tuning the subnano-sized transport channels, the organic-inorganic composite membrane exhibited high-efficient separation performance for small molecules such as organic solvent, water, and gases. By debottlenecking the scalable fabrication of organic-inofganic composite membrane. Nanjrtg Tech University collaborated wrth Nanjing JIUSI Company realized the membrane scale-up. building a production line of 10.0000 ㎡/year. Compared withh state-of-the-art organic-organic composite membranes, the PDMS-ceramic compose membrane product showed higher permeate flux with the same separation factor for organic solvent recovery (e.g. ethanol/water separation). Such high-performance PDMS composite membrane has been successfully applied for over 60 industrial plants for organic solvent recovery including olefins, organohalogen and oil vapors. For instance, applying the membrane for n-hexane recovery in pharmaceuticals industry, the recovery rate was doubled compared with original adsorption- based technique, and meanwhile the discharge was reduced by more than 90%, and the membrane has been stably operated in field for more than 5 years. These industrial organic solvent recovery projects based on organic-ceramic composite membrane realized remarkable benefits both in economics and society.

High-alcohol liquor is usually prepared from raw wine with traditional distillation at high temperature in order to produce brandy. Recently, a specific membrane material and corresponding pervaporation technology were developed at Membrane Science and Technology Research Center of Nanjing Tech University. It extracts the concentrate liquor (alcohol degree ≥ 40 vol.%) and remains the non-alcohol wine containing color and partial nutrient compounds (< 0.5 vol.%) at low operating temperature (T ≤ 40 °C). The technology has been successfully industrialized by Jiangsu Long Membrane High-tech Co., Ltd. and the membrane trademark is "Long Membrane". A Chinese producer of Wine and brandy, Xinjiang Citic Guoan Wine Co., Ltd., has installed the membrane system to produce a new-style brandy named as "Scheherazade" (a legendary Arabic queen). The brandy has an alcohol content of 52 vol.% and retains well the fruit aroma of raw wine. Taste test remarks that the brandy is as soft, full-bodied and luscious. The brandy-contained water is 100% from the grapes, without any additives during the whole process. Spreading application of alcohol pervaporation technology could promote Wine and liquor commodities with new tastes and brands.
