Membrane Separation and Concentration Technology for Wine

Product Overview

This membrane separation and concentration system provides integrated clarification, stabilization, concentration, and flavor preservation for grape juice and wine processing. Utilizing microfiltration, ultrafiltration, nanofiltration, and reverse osmosis, the technology removes impurities, adjusts alcohol content, concentrates sugars, and recovers pomace, ensuring clear, high-quality products while improving resource efficiency and environmental performance.

Working Principle

• Clarification: Microfiltration (MF) removes suspended solids and bacteria, producing clear and transparent grape juice or wine.
• Sugar Purification and Concentration: Nanofiltration (NF) concentrates and purifies sugars, enhancing body, flavor, and mouthfeel.
• Alcohol Adjustment: Reverse osmosis (RO) regulates alcohol content to meet specific market requirements.
• Stability Treatment: Ultrafiltration (UF) removes unstable proteins and polyphenols, improving wine stability and preventing haze or sediment formation.
• Process Water Purification: Membrane filtration ensures production water quality, avoiding negative impact on wine characteristics.
• Pomace Recovery: Membrane technology enables efficient recovery of grape pomace, improving resource utilization.

Key Features

• High-Efficiency Clarification: Rapidly removes suspended solids and impurities, ensuring clear, transparent wine.
• Flavor and Stability Preservation: Maintains wine aroma and taste while removing unstable components, enhancing storage stability.
• Resource Recovery: Recovers unfermented juice and grape pomace, maximizing raw material utilization.
• Environmentally Friendly: Reduces additive use and environmental impact.
• Flexible Operation: Multi-stage and parallel membrane design allows process adjustment for continuous production and varying production needs.

Applications

• Wine Production: Clarification, stabilization, sugar purification, and alcohol adjustment for high-quality wine and efficient production.

• Fruit Juice Manufacturing: Clarifies and concentrates fruit juices while preserving flavor and nutrients.
• Beverage Industry: Suitable for tea beverages, soft drinks, and other liquid products requiring clarification and concentration.
