Milk concentration is a vital process in the dairy industry, which is crucial for extending product shelf life, reducing costs, and producing high-value products. Traditional thermal evaporation methods have drawbacks such as nutrient loss and high energy consumption, while membrane technology has become a preferred alternative due to its low energy consumption, high separation efficiency, and excellent nutrient retention. This paper elaborates on the role of membrane technology in milk concentration, focusing on the application of three core membrane technologies (ultrafiltration, reverse osmosis, and nanofiltration), and analyzes their advantages in nutrient retention, product quality improvement, and green production.
Aiming at the technical pain points of traditional milk processing, this paper analyzes the practical application value of membrane separation technology in dairy industry. Combined with different membrane types including microfiltration, ultrafiltration and reverse osmosis, this study expounds the functions of impurity removal, sterilization, nutrient retention and component separation in raw milk treatment. Meanwhile, it summarizes the advantages of low temperature, energy saving, high safety and high separation efficiency of membrane technology, and illustrates its important role in diversified dairy product processing and production process optimization. It provides technical reference for dairy enterprises introducing efficient milk processing equipment.
Membrane separation technology is applied in fruit wine processing to realize clarification, impurity removal and sterilization at normal temperature. It effectively intercepts pectin, protein, yeast residues and colloidal particles, while well retaining original flavor, aroma and nutrients of fruit wine. The technology solves turbidity, precipitation and short shelf life problems, features no chemical addition and low-temperature treatment, optimizes production process, improves product stability, and is widely used in industrial refining of various fermented fruit wines.
