TCM Extraction

Ultrasonic cavitation refers to the dynamic process of growth and collapse of micro-gas core cavitation bubbles in the liquid that vibrate under the action of sound waves, and when the sound pressure reaches a certain value.
When ultrasonic waves act on liquids, a large number of small bubbles can be generated. One reason is that partial tensile stress occurs in the liquid to form a negative pressure. The decrease in pressure makes the gas originally dissolved in the liquid supersaturate and escape from the liquid and become small bubbles. Another reason is that the strong tensile stress "tears" the liquid into a cavity, which is called cavitation.
Introduction：
Some micro-bubbles are more or less dissolved in the Chinese medicine material, and vibration is generated under the action of ultrasonic waves, which is the cavitation effect of ultrasonic waves. When the bubble is closed, it will generate thousands of atmospheres of pressure around it, forming a micro shock wave, which can cause the plant cell wall and the entire organism to rupture, and the entire rupture process is completed in an instant, which is conducive to the dissolution of active ingredients and promotes The active ingredient of the medicine enters the medium and is fully mixed with the medium, which speeds up the extraction process and improves the extraction rate of
the active ingredient of the medicine.
Advantage：
1)No heating required； 2)Extraction of pharmaceutical ingredients；
3) Less solvent consumption, saving
solvent；
4) Physical process, no chemical reaction occurs；
5) Extract ingredients refined
