Fully automatic macroporous resin adsorption unit

Characteristics of macroporous resin adsorption separation unit

Macroporous resin adsorption and separation technology is a new separation and purification process that uses special adsorbents to selectively adsorb the effective parts from traditional Chinese medicine compound decoctions and remove ineffective components. It can solve practical problems faced in the production of traditional Chinese medicine, such as large dosage, product moisture absorption, and heavy metal residue. The refined product obtained after treatment with macroporous resin adsorption technology can highly enrich the active ingredients, with few impurities, and the extraction yield is only 2-5% of the original drug, while the general boiling method is about 30% and the alcohol precipitation method is about 15%; It can effectively remove moisture absorbing components, which is beneficial for the production of various traditional Chinese medicine formulations and enhances product stability; Can effectively remove heavy metals. The extract obtained by the macroporous resin adsorption and separation process has a small volume, does not absorb moisture, and is easy to make into various aesthetically pleasing dosage forms, especially suitable for the production of granules, capsules, tablets, etc., upgrading the crude, large, and black preparations of traditional Chinese medicine to modern preparations. This technology will be one of the technological advancements that have a significant impact on the extraction process of traditional Chinese medicine and have a wide range of driving effects.

Introducing computer automatic monitoring technology in the separation process to achieve production control, detection automation, and pipeline transportation, improving equipment reliability and repeatability.
