Product Description

Product Overview

Tea Extraction and Deep Processing Membrane Separation Equipment

The Tea Extraction and Deep Processing Membrane Separation Equipment is a specialized integrated separation and purification system tailored for the tea processing industry. Based on advanced multi-stage membrane technology (Microfiltration - MF, Ultrafiltration - UF, Nanofiltration - NF), it is designed to address the core pain points of traditional tea extraction processes, such as low purity of target components, high loss of active ingredients, chemical reagent residues, and low utilization of tea by-products.

The system enables precise separation, purification, desalination, and concentration of tea extracts (from fresh tea leaves, dry tea, tea residues, etc.), efficiently removing impurities (tea residues, proteins, pectin, pigments, small-molecule sugars) while maximizing the retention of high-value active components such as tea polyphenols (TP), theanine (L-Thea), tea polysaccharides (TPS), and theine (CAF). Fully compliant with GMP, FDA, and ISO standards, it is widely applied in tea deep processing enterprises, functional food manufacturers, pharmaceutical raw material suppliers, and cosmetic ingredient producers, covering the entire industrial chain from tea raw material pretreatment to high-purity component extraction and terminal product refinement.

Core Advantages

1. Precise Component Separation & High Retention Rate

Customizes membrane configurations (MF/UF/NF) based on the molecular weight of tea active components:
* UF membranes (MWCO 1,000–5,000 Da) efficiently remove macromolecular impurities (proteins, pectin) with a removal rate ≥95%;
* NF membranes (MWCO 200–1,000 Da) realize desalination and concentration of target components, with retention rates ≥95% for tea polyphenols and theanine;
* Enables targeted separation of specific components (e.g., decaffeinated tea extract production by separating theine from tea polyphenols).
It avoids the 15–30% loss of active components caused by traditional processes such as hot water extraction and resin adsorption.

2. Low-Temperature Operation & Full Retention of Activity

3. Green Production & No Chemical Residues

Operates at 25–40℃ throughout the process, eliminating thermal denaturation of heat-sensitive tea components (e.g., theanine, tea polyphenols) and volatilization of functional substances. Especially suitable for processing high-value components such as theanine (which is sensitive to high temperatures), ensuring the biological activity and nutritional value of the final product.

Adopts pure physical separation without adding acids, alkalis, or organic solvents. It avoids chemical residues in final products (critical for food and pharmaceutical-grade tea ingredients) and secondary pollution from reagent waste. The permeated water (recovered during separation) can be reused for tea extraction or equipment cleaning, reducing water consump-tion by 20–30% and complying with global green manufacturing trends.

4. High Efficiency & Value Enhancement

5. Strong Adaptability to Tea Extracts

The integrated "extraction-purification-concentration" process shortens the production cycle by 40% compared to traditional multi-step processes (e.g., "hot water extraction - centrifugation - resin adsorption - drying"). Energy consumption is only 1/3–1/5 of that of vacuum thermal concentration, saving 30–60% of energy costs. It also realizes high-value utilization of tea by-products (e.g., extracting tea polysaccharides from old tea leaves and tea residues), increasing the overall value of tea raw materials by 8–15 times.

Handles diverse tea-derived feed liquids, including high-viscosity tea extracts (viscosity ≤50 mPa·s), acidic tea polyphenol extracts (pH 3–6), and tea residue extracts with high impurity content. The anti-fouling membrane design (hydrophilic modified coating) effectively reduces the adhesion of proteins and pectin, ensuring stable operation with flux fluctuation ≤5% within 6 months even for long-term continuous production.

Main Features

1. Modular Design & Scenario-Specific Configuration

2. Intelligent Automatic Control

Supports customized combination of membrane modules based on tea deep processing directions (e.g., tea polyphenol purification, theanine separation, instant tea powder clarification, tea polysaccharide extraction). Processing capacity ranges from 50 L/h (laboratory R&D) to 100 m³/h (industrial mass production), adapting to new factory construction and old production line upgrades.

Equipped with a PLC control system and touchscreen operation interface, it realizes real-time monitoring and automatic adjustment of key parameters (pressure, flow rate, temperature, concentration of tea polyphenols/theanine, TDS). Supports unattended operation, automatic circulation separation, and abnormal alarm functions (e.g., high pressure due to membrane fouling, insufficient component retention rate), reducing manual intervention and human error.

3. Integrated CIP Cleaning System

4. Anti-Fouling & High-Durability Membranes

5. Compact Structure & Easy Maintenance

Built-in online Clean-in-Place (CIP) system with acid, alkali, and enzyme cleaning programs. Automatically cleans membrane surfaces and pipelines to remove protein adsorption, colloidal deposition, and pigment fouling without disassembly. Quickly restores membrane flux and extends membrane service life to 2–3 years under normal operation and maintenance.

Membrane materials adopt food-grade PVDF (polyvinylidene fluoride) and PES (polyethersulfone), featuring excellent chemical resistance (pH 1–14) and mechanical strength. The special anti-fouling coating reduces the adhesion of tea components, ensuring stable separation efficiency and reducing maintenance frequency.

Adopts a skid-mounted integrated design, reducing floor space by 40% compared to traditional split equipment, which is suitable for factories with limited space. Key components (membranes, pumps, filters) are standardized and modular, enabling quick disassembly, replacement, and low maintenance difficulty.
