Membrane Filtration Technology for Chinese Herbal Health Wine Production
Background Introduction
Chinese herbal health wine is a kind of wine with health-care effects, produced by taking Baijiu or rice wine as the base wine, adding Chinese medicinal materials, through fermentation, soaking, or blending medicinal liquid with wine.
The turbidity and precipitation of Chinese herbal health wine based on Baijiu are mainly caused by abundant colloidal substances in medicinal herbs. The particle size of colloidal substances causing loss of gloss is only nanoscale. Conventional diatomaceous earth filtration cannot meet requirements due to low filtration accuracy.
The problem of turbidity and precipitation of Chinese herbal health wine soaked with rice wine as base wine is more complicated than that of Baijiu-based health wine. The components in Chinese herbal extract are intricate. Under certain conditions, some substances can react with charged caramel color, protein and other substances in rice wine to generate new polymers, resulting in turbidity and precipitation of wine liquid.
Membrane Filtration Production Process for Chinese Herbal Health Wine
Medicinal Herb Soaking → Pretreatment Filtration → Storage Tank → Blending → Membrane Filtration → Follow-up Processes
Advantages of Membrane Filtration Technology in Health Wine Production
① The precise interception function of membrane elements thoroughly intercepts macromolecular impurities with an interception rate of over 99%. The filtrate features high clarity and light transmittance, no re-turbidity and no "secondary precipitation" after long-term placement;
② Pure physical operation at ambient temperature, no filter aids required, no chemical reactions. It will not damage heat-sensitive components or affect the flavor of wine;
③ Adopts advanced modular design; filter media can be replaced conveniently with simple operation;
④ Equipped with on-line regeneration cleaning and drainage devices to reduce labor intensity and production costs and improve production efficiency;
⑤ The whole set of equipment adopts sanitary-grade materials and complies with GMP certification standards.
Typical Applications
Chinese herbal health wine, marine biological wine, health-preserving wine, deer blood wine, pilose antler wine, seahorse wine, deer penis wine, ginseng wine, wolfberry wine, etc.
