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.
This paper introduces the application and strengths of double-pass RO water treatment systems in pharmaceutical production. The two-stage reverse osmosis device made of 304 stainless steel can efficiently remove salts, microbes and impurities to produce stable high-purity purified water, equipped with intelligent automatic monitoring and customizable water output schemes. Besides pharmaceutical factories and labs, the system is also applicable to electronics, food, chemical and new energy industries as a reliable industrial water purification solution.
Our factory produces integrated skid-mounted tubular ultrafiltration membrane wastewater treatment units. With wide flow channels, the equipment effectively resists clogging and handles high-turbidity wastewater from printing, food, chemical industries and more. It features stable water yield, automatic online cleaning and reusable standard effluent, realizing low-cost industrial wastewater recycling and up-to-standard discharge.
