FIELD: process engineering.
SUBSTANCE: proposed device comprises outer drum accommodating helical insert, filter, inlet, branch pipe and filtrate and thickened fraction discharge branch pipes. Proposed device differs in that the filter with constant-pitch helical lines is composed of three or more perforated rectangular strips of curved shape of different order and degree or curvature with centers of perforated surface curvature located inside or outside of filter cross-section.
EFFECT: simplified design, expanded operating performance.
