Application of Membrane Separation Technology in Zanthoxylum Bungeanum Oil Refining: Resolving Turbidity and Precipitation While Preserving Natural Numbing Aroma
Membrane separation overcomes bottlenecks of conventional prickly‑ash oil refining. It completes impurity removal, degumming and clarification under ambient temperature. The technology solves quality issues including turbidity and precipitation, preserves authentic fresh‑numbing aroma, raises oil yield and reduces solid waste and wastewater. It provides an efficient and modern process for deep processing of Zanthoxylum bungeanum oil.
Industrial Cross-Flow RO Membrane System for Herbal Extract Solvent Recovery
Massive organic solvent is adopted in the extraction process of herbal medicines and botanical active ingredients. Traditional solvent recovery relies on multi-stage distillation, which requires high temperature, consumes large amounts of steam and leads to loss of heat-sensitive active substances. Meanwhile, distillation equipment occupies huge workshop space and brings high operation costs. Cross-flow reverse osmosis membrane separation realizes solvent recovery at mild temperature via pressure-driven molecular interception. It traps macromolecular active compounds while allowing low-molecular alcohol solvent to penetrate the membrane. This paper introduces the working principle, integrated skid structure, complete production workflow and industrial strengths of solvent recovery RO membrane equipment. Compared with traditional distillation devices, the membrane system cuts energy consumption, retains active ingredient activity and reduces production costs, providing a low-carbon recy
Industrial Cross-Flow Ultrafiltration System for Soy Protein Concentration and Desalination
With the rapid growth of the plant-based protein market, soybean protein has been widely used in meat substitutes, protein beverages and functional food manufacturing. Traditional soybean protein production adopts water extraction and thermal drying processes, which contain high salt content, residual soluble sugar and small molecular impurities. Thermal concentration easily causes protein denaturation, poor solubility and heavy energy consumption. Cross-flow ultrafiltration membrane technology realizes low-temperature physical purification and concentration by molecular weight screening, intercepting macromolecular soybean protein while removing inorganic salts and soluble heterozygous substances. This paper introduces the structural design, working principle, production process and industrial advantages of the soybean protein dedicated ultrafiltration system. The membrane equipment effectively improves protein purity, maintains protein functional activity and reduces production energ
