CRM Ceramic Membrane in Tea Beverage Processing
1. Clarification and Purification of Tea Extract
After tea extraction and coarse filtration, CRM ceramic membranes can further remove fine tea residues, suspended particles, and some colloidal impurities, making the tea liquor clearer and more stable. This is a key step in the pretreatment of tea beverages.
2. Providing a Stable Feed for Low-Temperature Concentration
If tea extract enters the concentration stage directly, impurities and colloids may increase equipment load and negatively affect concentration efficiency and final product stability. After ceramic membrane treatment, the liquid becomes cleaner and more uniform, making it more suitable as feed for low-temperature concentration.
3. Pretreatment for Ready-to-Drink Tea Filling
Before liquid tea filling, the clarity and stability of the feed liquid are critical. CRM ceramic membranes can serve as an important purification unit before filling, reducing the risk of turbidity, sedimentation, and haze formation during storage.
Main Advantages of CRM Ceramic Membranes
· Better Retention of Original Tea Flavor
CRM ceramic membranes use a physical separation process that is relatively mild. While achieving clarification and impurity removal, they help preserve the original aroma and taste of the tea.
· Clear and Bright Filtrate with Low Risk of Haze Reappearance
Ceramic membranes effectively retain fine particles and some unstable colloids, resulting in a clearer filtrate and improved storage stability.
· Better Conditions for Downstream Concentration and Drying
After membrane treatment, the tea liquid contains fewer impurities and has a more stable system, which helps reduce the load on downstream concentration and improves process continuity. This is especially suitable for instant tea powder and tea concentrate production.
· Suitable for Continuous Production
CRM ceramic membrane systems operate stably and can be easily integrated with extraction, concentration, blending, and filling processes, improving overall production efficiency.
· Good Cleaning Recovery Performance
Alumina ceramic membranes are resistant to acids, alkalis, and high temperatures. They are suitable for CIP cleaning, have a long service life, and are well suited for long-term use in food factories.
