Process Brief:
The integrated membrane separation technology based on inorganic ceramic membranes effectively resolves key challenges in tea beverage production. Ceramic ultrafiltration membranes remove macromolecular proteins and pectins from tea infusions, while maximizing the retention of active components such as tea polyphenols, caffeine, amino acids, and catechins – thereby preserving the flavor and stability of the final product. The clarified tea liquor is then concentrated using reverse osmosis (RO) membranes, replacing conventional evaporation concentration processes and further safeguarding the retention of valuable ingredients.

Technical Advantages:

• Simplified process flow and significantly shortened production cycles;

• Asymmetric membrane pore distribution enabling online backwashing;

• High filtration precision, yielding clear and stable tea liquor with excellent clarity, effectively eliminating "tea haze" (cloudiness upon cooling);

• Minimal loss of active components (tea polyphenols, caffeine, amino acids, etc.) with improved product purity;

• Ceramic membranes exhibit strong fouling resistance, require minimal pretreatment of tea liquor, and maintain high-flux filtration over extended operation.
