large capacity ultrasonic herb extract machine for essential oil extracting
Ultrasonic extraction:
Ultrasonic extraction is a technology that uses the cavitation effect, mechanical effect and thermal effect of ultrasonic wave to extract the effective components of substances (herbs) by increasing the moving speed of medium molecules and increasing the penetration of medium.
Ultrasonic cavitation
Ultrasonic waves vibrate 20000 times per second to increase the dissolved microbubbles in the medium, form a resonant cavity, and then close instantaneously to form a powerful microshock, break the plant cell wall and make the effective components flow out. This is the extraction process of ultrasonic cavitation.
Mechanical effect
The propagation of ultrasonic wave in the medium can make the medium particles vibrate in its propagation space, so as to strengthen the diffusion and propagation of the medium, that is, the mechanical effect of ultrasonic wave.
Thermal effect
In the process of ultrasonic propagation, the sound energy is continuously absorbed by the medium and converted into heat energy in whole or in large part, resulting in the increase of the temperature of the medium itself and the medicinal tissue, and promoting the dissolution of effective components, which is the thermal effect of ultrasonic.
