Abstract
In a liquid-liquid centrifugal extractor wherein a liquid of greater specific gravity is introduced into an inner peripheral portion inside a rotor, while a liquid of smaller specific gravity is introduced into an outer peripheral portion, and the two liquids are brought into direct contact by exploiting the difference of the specific gravities thereof, to move an extract contained in one of the liquids into the other liquid, pipe means or groove-shaped members having a large number of small holes and serving to distribute the liquids are arranged in the outer peripheral portion and the inner peripheral portion inside the rotor in such a manner that they extend in parallel with a shaft for the rotor and that the holes of the means or members in the outer and inner peripheral portions face each other.
