The ultrasonic extractor manufacturer $n Shuangjia ultrasonic extractor mainly uses the principle of ultrasonic action. The fast mechanical vibration wave generated by the piezoelectric transducer acts on the cell wall (cell membrane) of the input material. The powerful mechanical wave can destroy the cell wall of plant cells (cell membrane of animal cells), so that the internal soluble substances in cells can be quickly dissolved into the extraction solvent, and then the extract can be obtained through filtration, centrifugation, ethanol precipitation, concentration, spray drying and other processes.
