aditional Chinese medicine (TCM) extract contains a large quantity of suspended particles, plant fibers, colloids and macromolecular impurities after decoction. The conventional clarification methods such as plate-and-frame filter press, alcohol precipitation and centrifugation have obvious drawbacks: long processing cycle, high loss of active ingredients, poor filtrate clarity and unstable product quality. The cross-flow ceramic membrane clarification technology, as a physical separation method, can efficiently remove suspended solids and colloidal impurities at low temperature while retaining target active components. It avoids the use of large amount of ethanol, reduces solvent recovery cost and lowers the risk of active substance degradation. This paper describes the separation principle, system composition, process control, membrane fouling control and industrial application benefits of ceramic membrane applied in TCM extract clarification. It also compares ceramic membrane with t
Laboratory membrane separation equipment is specially designed for universities, research institutions, and enterprise R&D centers. It can help customers obtain key process parameters and corresponding cleaning schemes through experiments, providing references for scientific research and industrial
When buying a centrifuge, don’t just focus on price—comprehensive after-sales support is the key to reducing costs. A chemical enterprise once suffered over 100,000 USD in losses due to a sudden centrifuge failure causing a 3-day shutdown—all avoidable with proper after-sales support. Our centrifuge
