Membrane Separation Process for Banlangen (Isatis Root) Granules: A High-Efficiency and Energy-Saving Modern Extraction Technology

Banlangen (Isatis Root) Granules are a commonly used proprietary Chinese medicine prepared from single-ingredient Isatis root, known for their effects in clearing heat, detoxifying, relieving sore throat, and providing anti-inflammatory benefits. They are widely used for the prevention and treatment of colds. Traditional preparation processes typically employ water extraction combined with evaporation concentration, which suffer from issues such as prolonged production cycles, high energy consumption, and substantial ethanol usage, thereby limiting further improvements in production efficiency and product quality. The introduction of membrane separation technology into the industrial production of Banlangen Granules has effectively addressed these bottlenecks, achieving integrated optimization of the extraction and concentration processes.

The membrane separation system can simultaneously accomplish both the clarification and concentration of the Banlangen aqueous extract, removing impurities, precipitates, and inactive components while enabling gentle concentration of the active ingredients. This process offers stable operation and extended membrane service life. With regular cleaning, membrane flux can be rapidly restored, significantly reducing operating and maintenance costs.

Technical Advantages of Membrane Separation for Banlangen Granules

Integrated Clarification and Concentration – The membrane system combines extract clarification and concentration functions, replacing traditional multi-step processing for a more streamlined and efficient workflow.

Ambient-Temperature Concentration for Heat-Sensitive Component Protection – The entire concentration process is carried out at ambient temperatures, avoiding degradation of heat-sensitive components in Banlangen and ensuring the efficacy of the final product.

Energy Savings and Reduced Operating Costs – Membrane concentration consumes significantly less energy than traditional thermal concentration, greatly reducing steam usage while minimizing ethanol loss, resulting in substantially lower overall production costs.

Anti-Fouling Design for Stable Operation – The cross-flow filtration mode effectively mitigates membrane fouling and clogging, enabling continuous and stable system operation suitable for industrial-scale production.

Compliant Materials Meeting Pharmaceutical Standards – All piping and components in contact with the medicinal liquid are manufactured from sanitary-grade materials that comply with GMP standards, ensuring product safety and consistency.

Membrane separation technology provides an energy-saving, highly efficient, and controllable modern solution for Banlangen Granule production. It not only improves product yield and quality but also offers technical support for the green manufacturing of TCM preparations.
