Chinese herbal medicine is extracted with ethanol after superfine grinding. How to filter?

According to the depth of grinding technology and the change of physical and chemical properties and application performance of powder materials, fine powder and fine powder are generally divided into 10- 1000 micron (fine powder), 0. 1- 10 micron (ultrafine powder) and 0.001-0. Ultra-fine powder less than 0. 1 μ m is difficult to be completely processed. Generally, the processing and corresponding classification technology of ultra-fine powder of 0.1-kloc-0/0μ m is called ultra-fine grinding.

Ultra-fine pulverization technology is to use ultrasonic pulverization and ultra-low temperature pulverization technology to make the central particle size of medicinal materials below 5 ~ 10 micron, and the cell wall breaking rate reaches 95%. Effective components are easy to be extracted and directly absorbed by human body. The application of this new technology is not only suitable for all kinds of medicinal materials with different textures, but also can directly expose the effective components, thus making the dissolution and action of pharmaceutical components more rapid and complete. The dissolution rate of effective components in traditional Chinese medicine is related to the degree of drug crushing. The dissolution test of Panax notoginseng with different crushing degrees in vitro was carried out. The results showed that the dissolution amount of Panax Notoginseng and total saponins of Panax Notoginseng at 45min were as follows: micropowder >; Fine powder > coarse powder > granules.
