Devices for carrying out mechanical, chemical and/or thermal processes

A device for carrying out mechanical, chemical and/or thermal processes in a housing (3) comprising mixing and cleaning elements (5) on shafts (1, 2) having axes (A), wherein the mixing and cleaning elements (5) of the shafts (1, 2) engage into one another when they rotate about the axes thereof, and two axially successive mixing and cleaning elements (5) are arranged at least on one shaft (1, 2) respectively such that they are rotationally symmetrical by about 180° in relation to one another about the axis (A) of the at least one shaft (1, 2) thereon, the mixing and cleaning elements (5) each consist of a disk element (6), and the disk element (6) has an outer marginal edge (7), which extends by a radius (r) in an arc segment of about 90° or slightly higher about the axis (A) of the shaft (1, 2) and is adjoined at both ends by side edges (8.1, 8.2) extending toward the shaft (1, 2), wherein one or more bars (9.1, 9.2) sits/sit on each marginal edge (7).

A device for carrying out mechanical, chemical and/or thermal processes in a housing (3) comprising disk-shaped mixing and cleaning elements (5) which are spaced apart on shafts (1.1, 2.1) having axes, wherein the mixing and cleaning elements (5) of each of the shafts (1.1, 2.1) engage into one another when they rotate about the shaft axes thereof such that the disk surface and a lateral surface of the shaft are cleaned, wherein the cross section of the shaft (1.1, 2.1) has a polygonal form.

A device for carrying out mechanical, chemical and/or thermal processes in a product in a housing (3) comprising a discharge opening (12) and comprising mixing and cleaning elements (5) on shafts (1, 2) having axes, wherein the mixing and cleaning elements (5) of the shafts (1, 2) engage into one another when they rotate about the shaft axes thereof, the discharge opening (12) is arranged in an end plate (4) or in/on a cylindrical part of the housing (3), and the discharge opening (12) is assigned a discharge element (14, 15) which rotates with the shaft (1, 2) and/or the mixing and cleaning elements (5).
