Applications of Continuous Membrane Concentration Equipment in Food & Biotech Industry

Introduction

Continuous membrane concentration is an energy-saving, low-temperature separation technology widely adopted in modern large-scale production lines. Different from traditional batch membrane concentration, this system realizes continuous feeding, continuous permeate discharge and continuous concentrated product output, supporting 24-hour stable automatic operation without frequent shutdown for tank transfer. Constructed with full sanitary stainless steel pipelines and modular membrane components, it fully meets GMP hygiene standards for food, pharmaceutical and biological processing.

Main Application Scenarios

1. Dairy Processing

   It is the core equipment for whey protein concentration and lactose recovery. The membrane intercepts protein molecules while draining water and partial salt, avoiding thermal denaturation of WPC. Stable continuous running ensures uniform solid content of finished whey products.

2. Fruit & Vegetable Juice Production

   For NFC fruit juice, tea extract and pectin liquid, the equipment completes room-temperature concentration without evaporation. It retains original flavor, aromatic substances and natural nutrients, and greatly reduces steam consumption compared with multi-effect evaporators.

3. Herbal & Plant Extraction

   Chinese herbal extracts, plant flavonoids and saponin solutions can be concentrated and desalted synchronously. Low-temperature operation protects active pharmaceutical ingredients, lowering loss of effective components during processing.

4. Fermentation Broth Treatment

   Used for concentrating amino acids, yeast liquid, enzyme preparations and microbial fermentation liquid. It removes water and small-molecule impurities continuously, improving product yield and shortening material circulation time.

5. Bio-pharmaceutical Manufacturing

   Suitable for concentration and diafiltration of recombinant protein, polypeptide and vaccine stock solution. The automatic constant-concentration control system avoids concentration fluctuation, meeting strict pharmaceutical production requirements.

Core Advantages for Industrial Use

• Ambient temperature operation, no phase change to preserve heat-sensitive substances

• Continuous steady production, less labor cost and stable product quality

• 70%-90% energy saving versus thermal evaporation equipment

• Support online CIP cleaning without stopping the whole production line

• Long service life of membrane elements with low pollution rate under constant cross-flow shear

Conclusion

Continuous membrane concentration equipment has become a standard supporting facility for medium and large production factories. Its wide adaptability across dairy, beverage, plant extraction and biopharmaceutical fields makes it a cost-effective alternative to traditional thermal concentration machinery.
