How to quickly extract the active ingredients in the medicine is an important step in the development of the traditional Chinese medicine industry. The traditional method of extracting the active ingredients of the medicine is to use artificial boiling. After the active ingredients in the medicine are extracted, the residue is taken out by artificial filtration, which is not only time-consuming and labor-intensive, but also troublesome. There is also a steam boiling method, but the steam boiling method often requires a large amount of steam, and after the steam enters the extraction tank, due to the temperature change in the extraction tank, it is difficult for the steam to achieve 100% heat release. Heating the water in the extraction tank often results in the water temperature in the extraction tank not being high enough. In addition, when extracting the active ingredients of the medicine, the medicine is in a static state in the extraction tank for a long time, resulting in insufficient extraction of the active ingredients of the medicine.
