Juice Membrane Filtration Flux Keeps Dropping? It Is Not Damaged Membranes, But Poor Pretreatment
Steady juice membrane performance relies heavily on proper pretreatment. Optimizing upstream processes is the most cost‑effective way to reduce fouling, extend membrane life and stabilize production.
Clarified Tangerine Peel Filtrate: Upgrade Herbal Liquid With Membrane Separation Technology
Traditional tangerine peel (Chen Pi) raw liquid suffers from turbidity and precipitation caused by colloids, pectin and macromolecular impurities, restricting its industrial application. Membrane separation technology realizes low‑temperature physical clarification for tangerine peel liquid. It removes colloidal impurities while retaining core active substances such as hesperidin and flavonoids. Compared with conventional filtration, this technology delivers high‑clarity golden filtrate, avoids thermal damage to ingredients, cuts consumable costs, and improves product stability and shelf‑life. The processed tangerine peel filtrate can be used for functional beverages, food flavorings, herbal intermediates and cosmetic raw materials. We provide customized membrane separation solutions for plant extract clarification.
Advanced Nanofiltration Membrane Technology for Deep Purification And Refining of Traditional Chinese Medicine Extracts
The crude extraction liquid of traditional Chinese medicine contains extremely complex multicomponent mixtures after water extraction or alcohol extraction, including target active pharmaceutical ingredients, macromolecular colloids, residual plant fibers, tannins, inorganic salts, heteropolysaccharides and pigment impurities. Traditional refining technologies such as alcohol precipitation, resin adsorption and vacuum thermal concentration are difficult to achieve precise impurity removal, and usually cause problems such as active ingredient loss, low purification accuracy, high energy consumption, solvent residue and unstable batch quality. In modern standardized Chinese medicine pharmaceutical production, higher requirements for clarity, safety, stability and efficacy consistency have gradually eliminated outdated traditional processes. Cross-flow nanofiltration membrane separation technology relies on dual mechanisms of molecular weight screening and charge repulsion to realize low-
