FIELD: chemical engineering. SUBSTANCE: device has a housing, the systems for feeding and removing the granular material and the liquid and a mixing body. The latter is made in the form of two sleeves coaxially mounted and forming cavities between themselves and the housing in its upper part. One end of the sleeves is connected with the system of feeding the liquid through the packing having holes and a hose. The system is at the same time the drive of the mixing body. The other ends are hermetically fastened in the housing. The housing is equipped with an additional branch pipe (by-pass) located in its lower part and being in communication with the formed cavities and the system of the liquid outlet. The interior and exterior sleeves are made air-tight and porous, correspondingly. EFFECT: enhanced efficiency of the device operation and reduced metal usage. 1 dwg
