Basic Principles Of Ultrasonic Extraction And Existing Problems

When big energy extraction of ultrasonic wave ACTS on the medium, the vibration are in a state of thin, medium is torn into many small hole natural product extraction equipment, instantaneous is closed, these small holes up to thousands of atmospheric pressure transient pressure when closed, the cavitation phenomenon. The strengthening effect of ultrasonic on the extraction and separation of various components is mainly due to its cavitation.

Cavitation in the great pressure caused by the tiny air bubbles burst to the bursting of the broken cell wall and the whole organisms in instantaneous, shortens the time of break and at the same time, the effects of the vibration ultrasonic enhanced the release of intracellular substances, diffusion and dissolution, can significantly improve the efficiency of extraction. Ultrasonic crushing process is a physical process, there is no chemical reaction in the process, the extracted biological active substances remain unchanged.
