Application of Membrane Filtration and Membrane Concentration in Tea Powder Production
This article introduces the application of membrane filtration and membrane concentration technology in tea powder manufacturing. Different from traditional high-temperature thermal concentration, membrane separation operates under low-temperature room-temperature conditions. Microfiltration and ultrafiltration remove tea residues, colloids and suspended impurities to clarify tea leachate, while nanofiltration and reverse osmosis concentrate tea extracts without damaging tea polyphenols, tea aroma and active nutrients. The integrated membrane system reduces energy consumption, shortens spray drying cycles and improves the solubility, flavor and stability of finished instant tea powder, suitable for mass processing of green tea, black tea and oolong tea powder.
Nanofiltration Membrane Concentration Technology for Energy-Saving and High-Purity Dairy Processing Abstract
The global dairy industry is shifting toward energy-saving production, high-purity ingredients, and customized functional dairy products. Traditional dairy concentration processes relying on multi-effect evaporation and ultrafiltration single-stage separation face common drawbacks including high energy consumption, inaccurate interception of small molecular nutrients, and uncontrollable mineral content, limiting the quality upgrade of milk base materials, whey products, and functional dairy ingredients. As a precise pressure-driven membrane separation technology, nanofiltration (NF) membrane technology features unique molecular sieving and selective desalination functions, which can efficiently concentrate dairy raw liquids while removing excess monovalent salts and impurities. This paper systematically introduces the working principle, technical characteristics, industrial process, and practical application value of nanofiltration membrane systems in dairy processing. Compared with tr
Flat Plate Centrifuge: Principle, Applications, Pros & Cons
This article introduces the working principle of flat plate centrifuges that separate solids and liquids via high centrifugal force, lists its common application fields including food, pharmacy, chemical industry and wastewater treatment, and summarizes the core advantages such as stable operation, compact structure and easy cleaning, as well as drawbacks of intermittent batch operation and regular filter cloth replacement. It offers clear reference for users selecting industrial solid-liquid separation equipment.
