Extraction and concentration of Radix Isatidis

Banlangen granules belong to traditional Chinese patent medicines and simple preparations made from single ingredient Banlangen. It is one of the traditional Chinese patent medicines and simple preparations widely used in daily life to fight colds. It can clear away heat, detoxify, and promote pharynx. In the process of preparing Banlangen granules, it is necessary to extract and concentrate Banlangen. The traditional preparation method combining water purification and evaporation concentration takes a long time and requires a large amount of thermal energy and ethanol. The application of membrane separation technology in the production of Banlangen granules will alleviate the above-mentioned problems and has been used in industrial production.

The use of membrane separation technology can not only effectively remove impurities, precipitates, and ineffective components, but also refine and concentrate the water extract of Radix Isatidis, making the production process of Radix Isatidis granules more convenient. During the production of Banlangen granules, the membrane components can be operated for a long time when processing Banlangen. By using appropriate cleaning solution during this process, the flux can be quickly restored, reducing the investment cost.

Advantages of Banlangen Particle Membrane Separation Technology

1. Membrane separation technology can not only clarify and remove impurities from the extract, but also concentrate and refine it. The concentration process belongs to room temperature concentration, which reduces energy consumption compared to thermal concentration, and has no functional impact on substances with high thermal sensitivity in the product;

2. The unique cross flow operation mode can effectively solve the problem of pollutant blockage;

3. Concentrate at room temperature, suitable for the concentration of all traditional Chinese medicine extracts, ensuring that the active ingredients are not destroyed and can be desalinated and ash reduced;

4. All pipelines in contact with the extraction solution are made of materials that meet hygiene requirements and comply with GMP and other certification standards;

5. Membrane concentration is a type of room temperature concentration that can reduce the loss of active ingredients caused by high temperature decomposition, ensuring product yield while saving a lot of steam and reducing energy consumption.
