Instant Tea Powder Membrane Filtration, Concentration And Equipment

The Instant Tea Filtration, Concentration and Dehydration Equipment, developed by Bluewav Technology Co., Ltd.—a National High-tech Enterprise with over 20 years of membrane separation expertise—is a specialized integrated solution tailored for the processing of instant tea products (Pu'er tea powder, black tea powder, dark tea powder, green tea powder, concentrated tea juice, etc.). Targeting core industry pain points in traditional instant tea production such as high impurity residue, significant aroma loss, and high energy consumption (from plate-frame filtration and vacuum concentration), this equipment adopts advanced membrane separation technologies (Microfiltration - MF, Ultrafiltration - UF, Nanofiltration - NF) combined with low-temperature drying processes.

It realizes three-stage integrated processing of tea extracts: pretreatment filtration to remove coarse impurities, refining filtration to intercept fine contaminants, and concentration/dehydration to enrich active ingredients. Operating at room temperature throughout the core process, the system maximizes the retention of tea's flavor substances (terpenes, aromatic alcohols) and functional components (tea polyphenols, theanine) while ensuring high clarity, solubility, and stability of the final product. Fully compliant with international food safety standards (GMP, FDA) and relevant national regulations, it has been widely applied in instant tea production enterprises, providing reliable support for high-quality and efficient production of instant tea products.

Core Advantages

1. Room-Temperature Processing, Retain Natural Flavors & Active Ingredients

Operates at 25-35℃ during filtration and concentration stages, avoiding thermal degradation of heat-sensitive components and volatilization of aromatic substances. The retention rate of tea polyphenols and theanine reaches ≥90%, ensuring the final product maintains the original tea's flavor and nutritional value.

2. Precise Layered Separation, Enhance Product Quality

Multi-membrane coupling technology achieves refined purification: MF removes ≥99% of tea residues and suspended particles; UF intercepts proteins, pectin, and colloidal impurities; NF selectively enriches target ingredients. The final instant tea powder has cold water solubility ≥95%, with no turbidity or precipitation after brewing, and light transmittance ≥98%.

3. Energy-Saving & Cost-Reduction, Green Production

NF concentration consumes only 30-40% of the energy of traditional vacuum concentration, significantly reducing steam and electricity costs. Pure physical separation without adding flocculants or preservatives, complying with food safety standards and reducing environmental pollution.

4. Customized Configuration for Different Tea Types

Tailors membrane selection and process parameters based on tea characteristics: hydrophilic PVDF or ceramic membranes for green tea to inhibit oxidation; appropriate pressure adjustment for fermented teas (Pu'er, dark tea) to remove macromolecular pigment polymers. Adapts to both small-batch R&D and large-scale industrial production.

5. Stable Operation & Easy Maintenance

Adopts cross-flow filtration design to reduce membrane fouling and extend cleaning cycles. Equipped with an online CIP cleaning system, membrane components can be reused for 2-3 years with regular maintenance, lowering long-term operating costs.

Main Features

1. Three-Stage Integrated Design

Integrates pretreatment filtration, refining purification, concentration, and dehydration (drying) functions in one system. The standardized process (MF pretreatment → UF refining → NF concentration → spray/freeze drying) simplifies production workflow, reducing equipment investment and floor space by 35% compared to traditional combined processes.

2. Intelligent Automatic Control

Equipped with a PLC control system and touchscreen interface, enabling real-time monitoring and automatic adjustment of key parameters (pressure, flow rate, temperature, concentration). Supports unattended operation, automatic backwashing, and abnormal alarm functions (overpressure, low flux), minimizing manual intervention and ensuring stable product quality across batches.

3. Durable & High-Quality Materials

All parts in contact with materials are made of food-grade 304/316L stainless steel, PVDF membranes, and ceramic membranes. Excellent chemical stability (pH 2-10) and corrosion resistance, adapting to acidic/alkaline tea extract environments and avoiding material leaching.

4. Flexible Drying Options

Provides spray drying (for conventional instant tea powder) and freeze drying (for high-value products) options. Spray drying produces uniform powder with good fluidity (moisture content ≤3%); freeze drying maximizes retention of aroma and active ingredients for premium products.

5. Turnkey Project Capability

Provides one-stop services from technical consultation, tea extract property analysis, pilot-scale verification, and equipment manufacturing to on-site installation, commissioning, and operator training. Seamlessly integrates with existing production lines (extraction tanks, centrifuges) to form a complete processing chain.
