FIELD: chemical engineering. SUBSTANCE: device has a housing, a mixer, branch pipes for the liquid inlet and outlet, branch pipes for the inlet and outlet of the granular material. The new feature of the device lies in the fact that the housing is equipped with two chambers mounted on its contrary face ends so that their open ends face each other. In one of the chambers (anechoic) a mixer is located which is made as a sleeve mounted for the reciprocal displacement. One end of the sleeve is turned inside out and is secured on the chamber. The other one is wound on the reversible drum. The second chamber, the receiving one, is connected with the branch pipe for removing the processed granular material. EFFECT: reduced metal usage and simpler design. 1 dwg
