Tea Polyphenol Extraction and Deep Processing Membrane Separation Equipment

Product Description

Product Overview

Tea Polyphenol Extraction and Deep Processing Membrane Separation Equipment

Developed by Zhengzhou Chlory Technology Co., Ltd.—a national high-tech enterprise with 20+ years of membrane separation and plant extract experience—this integrated equipment is tailored for tea polyphenol extraction, purification, concentration and deep processing using advanced membrane separation technology. It solves core pain points of traditional tea polyphenol processing: low extraction rate, loss of active ingredients (catechins, EGCG), low purity from residual impurities, high energy consumption, and poor product stability.

Integrating cross-flow microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and low-temperature concentration systems, it covers the entire process from tea leaf pretreatment, extraction, clarification, deep impurity removal, concentration to sterile collection. Adopting precise molecular sieving membranes (MWCO 5–10 kDa), it efficiently removes impurities (cellulose, proteins, tannins) while retaining ≥98% of tea polyphenol active ingredients. The whole process is pure physical operation at 20–35℃, avoiding thermal degradation, and fully compliant with GMP, FDA and food/pharmaceutical industry standards. It offers MZ/TC/UF series (50–5000 Kg/h) for pilot, medium and large-scale production.

Core Advantages

1. Low-Temp Operation & Activity Retention:

2. Precise Purification & High Purity: 

20–35℃ normal-temperature processing, avoiding tea polyphenol degradation, active ingredient retention rate ≥98%, ensuring EGCG and catechin activity, better than traditional high-temperature extraction.

"MF+UF+NF" three-stage purification, impurity removal rate ≥99.9%, tea polyphenol purity ≥98.5%, no residual impurities affecting product quality and stability.

3. Efficient Extraction & Concentration:

3. Anti-Fouling & Stable Operation:

Integrated extraction and membrane separation, extraction rate increased by 15–20% compared with traditional methods; concentration multiple 5–20x adjustable, directly meeting deep processing requirements.

Anti-adsorption PVDF/ceramic membranes + cross-flow operation, reducing membrane fouling by 65%; online CIP cleaning, flux recovery ≥95%, continuous operation ≥30 days, membrane life 2–3 years.

4. Energy-Saving & Cost-Reduction:

5. Flexible Adaptation:

Energy consumption only 30–40% of traditional evaporation; no chemical additives, avoiding secondary pollution and reducing raw material waste.

Customizable for different tea raw materials (green tea, black tea, oolong tea) and product requirements (food-grade, pharmaceutical-grade).
