Reverse Osmosis Membrane Technology for Concentrated Milk Production
Concentrated milk is widely applied in dairy beverage, bakery and ice cream industries. Traditional concentrated milk production mainly adopts vacuum evaporation, which requires high-temperature operation, consumes massive steam and damages heat-sensitive flavor substances and nutrients in milk. Reverse osmosis membrane technology realizes low-temperature concentration of milk by selectively intercepting milk solids while allowing water molecules to permeate the membrane. It reduces the water content of raw milk under mild conditions, retains natural milk aroma and nutritional components, and significantly cuts energy consumption. This energy-saving membrane process has become an important auxiliary concentration technology for modern concentrated milk manufacturing.
Nanofiltration Membrane Technology for Dairy Wastewater Treatment and Resource Recovery
Dairy production generates a large volume of wastewater containing milk protein, lactose, grease and inorganic salts. If discharged directly without proper treatment, such wastewater will cause serious organic pollution and waste recyclable valuable substances. Conventional biochemical treatment and precipitation processes consume large amounts of chemicals and fail to recover lactose and protein resources efficiently. Nanofiltration membrane technology can realize graded separation, concentration and desalination of dairy wastewater under mild conditions. It intercepts organic macromolecules such as residual protein and lactose while partially removing divalent salt ions, so as to recover usable dairy raw materials and produce reusable water. This integrated treatment and recycling scheme reduces pollutant emission and improves resource utilization rate, emerging as a sustainable solution for modern dairy plants.
# Ultrafiltration Membrane Technology for Raw Milk Standardization and Fine Purification
Raw milk collected from dairy farms contains complex heterogeneous components including somatic cells, residual bacteria, microscopic dust, colloidal protein aggregates and uneven fat globules. Traditional milk purification relies on pasteurization, centrifugal degreasing and precision filtration, which cannot completely remove micro-impurities and often cause damage to natural milk flavor and active nutrients. Conventional thermal treatment also fails to standardize milk composition, resulting in unstable taste and quality differences between production batches. Cross-flow ultrafiltration membrane technology achieves low-temperature physical purification, bacterial removal and ingredient standardization of raw milk under mild operating conditions. It effectively eliminates microorganisms and micro-colloidal impurities while completely retaining natural milk nutrients and original flavor. This advanced physical processing method greatly improves milk safety, purity and product consiste
