FIELD: mass-exchange apparatus for extraction processes in "liquid-to-solid" systems. SUBSTANCE: proposed device has vibration drive, central vertical cylindrical hollow column with spiral working member secured on its outer surface and unloading chute at the end of upper turn of working member. Mounted on center (in height of apparatus) and on upper turns of working member are splitters which may turn around vertical axis; pipe union for supply of extractant (discharge of extract) is mounted on lower turn; central column performing function of solid phase loading branch pipe has holes: one hole is found at level of bottom and other holes are opposite to it at level of splitters. EFFECT: extended field of application due to change of method of loading at simultaneous intensification of process. 3 dwg
