How the new experimental-grade ultrasonic extraction equipment works?

 

Introduce:Ultrasound acts as a well-controlled means of cell disintegration, for which the mechanical effect of ultrasound provides faster, more complete solvent penetration of the cellular material and improved transfer quality. Ultrasound can penetrate better into plant tissue and improve mass transfer. Ultrasound creates cavitation that disrupts cell walls and promotes the release of matrix components.

 


 

Principle of ultrasonic extractor:Ultrasound is an effective means to destroy cell structure. This effect can be used to extract substances within cells. For example, starch is extracted from the cell matrix. Ultrasound creates alternating high and low pressures in the exposed liquid. During the low-pressure cycle, the ultrasonic wave generates small vacuum bubbles in the liquid, and the vacuum bubbles are violently ruptured during the high-pressure cycle, which is called cavitation. The implosion of cavitation bubbles causes strong hydrodynamic shear forces. Shear forces can break fibers, fibrous materials into cell particles and disrupt the structure of cell walls. This releases substances inside the cells, such as starch and sugars, into the fluid. In addition to this, the cell wall material is broken into small fragments. Depending on the ultrasound parameters used, ultrasound can have a destructive or constructive effect on cells, depending on the ultrasoun parameters used.
