In the deep processing of tea, fruit juice, dairy products, and other food and beverage applications, impurity removal and retention of active ingredients have long been industry challenges. Leveraging a comprehensive range of proprietary membrane products including ceramic membranes, ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO), combined with multi-stage membrane integration processes, we provide efficient, stable, and customizable membrane concentration and clarification solutions for food and beverage manufacturers – enabling product upgrading and clean production goals.

I. Tea Beverage Clarification and Concentration – Eliminating "Tea Haze" While Locking in Flavor

Traditional tea beverage production often faces challenges such as cloudy tea liquor and flavor loss. Shandong Qisheng has developed a dedicated treatment solution using an integrated ceramic membrane + reverse osmosis (RO) system:

• Efficient clarification: Ceramic membranes precisely retain macromolecular proteins and pectins, effectively resolving "tea haze" (cold cloudiness), delivering clear permeate with high light transmittance and strong stability.

• Flavor retention: Core flavor compounds including tea polyphenols, caffeine, and amino acids are efficiently retained, ensuring pure taste and superior quality.

• Green process: Entire process requires no chemical additives – no residues, no pollution, aligning with healthy beverage trends.

• Energy-efficient concentration: RO operates at ambient temperature, replacing traditional high-temperature evaporation, reducing aroma loss and cutting energy consumption by over 40%.

This technology has been successfully applied in the processing of Hubei Qingzhuan tea extract, achieving long-term stability and zero sedimentation of the tea liquor, significantly enhancing product market competitiveness.

II. Fruit Juice Clarification and Pectin Extraction – Color Preservation, Flavor Protection, Improved Yield

In fruit juice processing, Shandong Qisheng ceramic microfiltration membranes offer advantages including fouling resistance, easy cleaning, and high flux:

• Effectively removes pulp, proteins, and other turbidity-causing components, reducing color degradation and flavor alteration caused by organic membranes.

• Supports integrated pectin extraction, improving product purity and processing yield.

• Membrane materials resist acids, alkalis, and steam sterilization, suitable for continuous production of various fruit types.

III. Full-Chain Dairy Processing Applications – From Sterilization to Protein Standardization

Shandong Qisheng ceramic ultrafiltration and microfiltration membrane technologies cover key stages in milk and whey processing:

• Microfiltration sterilization: Low-temperature physical retention of bacteria, preserving active nutrients.

• Protein concentration: Precise separation of whey protein and casein, enabling milk protein standardization.

• Yogurt and colostrum processing: Increases solids content and improves product texture.

• Anti-fouling design: Supports cleaning with strong acids, alkalis, and oxidizing agents, ensuring long service life and low overall cost.
