Abstract

A self-cleaning reactor/mixer, in particular a disk reactor, with a large available useful capacity, which cleans itself kinematically, comprising at least two or more parallel shafts rotating in the same direction, on which axially offset, not necessarily circular disks with scrapers distributed on their circumference are situated, and a surrounding housing. The reactor/mixer on account of the special geometry of its rotors, which extensively avoids acute product-side angles, is particularly suitable for processing solids-bearing materials to be mixed.
