Membrane Separation for Resveratrol Purification
Resveratrol is a heat-sensitive polyphenol antioxidant widely sourced from botanical raw materials. Traditional thermal concentration tends to destroy its active structure and lower product yield. Membrane separation technology provides an effective low-temperature purification route for resveratrol production. Combined tubular ultrafiltration and nanofiltration processes remove macromolecular impurities and concentrate target components without phase change. Tubular membrane equipment features strong anti-fouling performance, suitable for viscous plant extracts. Small and mid-pilot membrane systems enable parameter testing and process optimization. This technology reduces energy consumption, improves resveratrol recovery and purity, and supports clean manufacturing for nutraceutical and cosmetic raw material production.
Membrane Filtration and Concentration for Tea Deep Processing
Membrane filtration and concentration technology offers an efficient low-temperature purification method for tea deep processing. Combining microfiltration, ultrafiltration and reverse osmosis, it removes suspended solids, pectin and colloids from crude tea liquor at room temperature, avoiding thermal damage to tea polyphenols, theanine and natural aroma. This modular system supports lab, pilot and commercial scale production for tea juice clarification and concentration. It features low energy consumption, easy CIP cleaning and water recycling, ideal for ready-to-drink tea, instant tea powder and tea polyphenol raw material production.
Spiral Wound Ultrafiltration Membrane for Food & Beverage Clarification
Food and beverage manufacturers require gentle, low-cost clarification processes to preserve natural flavor, color and active ingredients while removing suspended solids, colloids and microorganisms. Spiral wound ultrafiltration (UF) membrane integrates large membrane area into compact pressure vessels, delivering continuous cross-flow filtration at moderate operating pressure. This paper describes the structural design, separation mechanism, core benefits, operational control and typical food industry applications of spiral wound UF systems. It also discusses fouling prevention and CIP procedures tailored for organic feed streams.
