Multi-layer Plate and Frame Filter | Sanitary Stainless Steel Plate Frame Filter for Liquid Clarification & Solid-Liquid Separation

Working Principle Raw material liquid is driven by the feed pump and fed into the multi-layer plate and frame filter, passing through stacked filter plates and frames sequentially. Liquid penetrates filter media such as filter paper, membrane or cloth, while suspended particles, impurities and bacteria in the liquid are trapped on the filter medium surface. Clarified filtrate collects through internal flow channels of filter plates and discharges from the outlet. After filtration, release the hand-crank clamping system and pull apart the plate-frame assembly to remove filter cake and replace or clean filter media. Reassemble and re-clamp after washing the plates to start the next filtration cycle. The machine features no dead corners for easy cleaning and prevents cross-contamination of materials. Application Fields Laboratory R&D: Small-batch filtration of test liquid, extract and reagent for formula testing, sample clarification and impurity removal. Fine Chemicals: Solid-liquid separation of additives, solvents and suspended feed liquid, removing suspended solids and improving product clarity. Pharmaceutical & Chemical: Clarification and sterile filtration of APIs and formulation intermediates, complying with sanitary-grade production requirements. Traditional Chinese Medicine Extraction: Clarification of herbal extracts and concentrated liquid, removing herb residues and suspended particles to improve liquid purity. Food Industry: Filtration and clarification of beverages, fruit wine, syrup and fermentation materials to remove suspended solids and stabilize product quality. Cosmetics Industry: Precision filtration of cosmetic stock solution, essence and plant extracts to eliminate particulate impurities and ensure smooth and clean finished products.
