Countercurrent extraction: Add a liquid solvent (extractant) that is insoluble or partially soluble in the liquid mixture to form a two-phase system. Use the difference in the distribution of each component in the mixed liquid in the two phases to allow more target components (solutes) to enter the solvent phase (extraction phase), thereby achieving separation. In continuous countercurrent extraction, light and heavy The two phases enter the equipment from the upper and lower ends respectively, and flow in relative countercurrent under the action of external force fields such as gravity or centrifugal force to complete the mass transfer operation; Ultrasonic effect: When ultrasonic waves propagate in a liquid medium, they will produce special cavitation effects and mechanical vibration effects, which can destroy the cell walls of the material and accelerate the dissolution and release of the target components, thereby improving the extraction efficiency.
