Tea Beverage Membrane Filtration Applications

Hollow fiber membrane filtration has become a mature and reliable industrial process in tea beverage production. It effectively retains suspended particles and macromolecular impurities in tea liquor, delivering efficient clarification and impurity removal.

This gentle physical process does not damage the original flavor, color, sugar content or other quality indicators of tea, helping preserve its natural character and making it an ideal clarification solution.

Yongji Filtration and Separation Solutions

Yongji Spiral-Wound Membrane Systems for Multi-Industry Separation and Purification

Yongji spiral-wound membrane systems cover microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO), and have been operating reliably in food and beverage, water treatment, pharmaceutical and chemical applications.

Based on material characteristics and capacity requirements, we provide customized, automated, efficient and energy-saving system solutions. Equipment design follows GMP standards, with technical support from bench-scale testing and pilot trials through to on-site application.

Yongji Diatomite Filtration System, A Mature and Reliable Traditional Filtration Solution

Diatomite filtration uses natural porous diatomite as a filter aid to form a stable filter cake layer. It effectively retains suspended particles, colloidal impurities and fine turbidity, and is a mature process widely proven in alcoholic beverages, drinks and fermentation industries.

For high-turbidity feeds, large batch variation or processes requiring rapid clarification, diatomite filtration still offers practical value that is difficult to replace. Yongji can provide filtration systems for beer, yellow rice wine, fruit wine, syrup, condiments, fermentation broth and other applications according to material characteristics and processing capacity.

Yongji Full-Series Plate Heat Exchange Sterilization Equipment

The plate heat-exchange structure provides strong turbulence, high heat-transfer efficiency and excellent heat recovery. The temperature control system enables stable constant-temperature operation with minimal fluctuation. The equipment can switch between two sterilization modes, supporting conventional low-temperature sterilization below 95°C and ultra-high-temperature instant sterilization at 135°C. It is suitable for continuous sterilization of liquid materials in alcoholic beverages, condiments, juices and other food processing fields.

Yongji plate heat exchange sterilization equipment features a high level of automation and an intelligent PLC control system. Heating, holding, cooling and reflux can run automatically without continuous manual supervision. The complete unit uses food-grade stainless steel, is easy to disassemble and clean, offers accurate constant-temperature control, switches between two sterilization modes with one touch, runs stably and energy-efficiently, and fits small, medium and large production lines while preserving product flavor and quality.
