Abstract

The invention relates to a fully self-cleaning reactor/mixer having a large freely usable volume, that cleans itself kinematically, consisting of two or more parallel shafts (2, 2') rotating in opposite directions, on which are located spirally arranged, axially offset paddles (3, 3') with scrapers (4, 4', 5, 5') on the front and rear of the paddles, and a surrounding housing (1). Since all the scrapers (4, 4') on the upstream side of the paddles (3, 3') convey the material concerned outwards and all the scrapers (5, 5') on the downstream side of the paddles convey the material inwards, axial conveyance is obtained.
