The mixing-drying reactor can process substances of widely differing consistencies. The machine, which dries in a fine vacuum, is also very flexible with regard to the filling level. It is suitable for both homogenization of a mixture and also for more intensive deagglomeration. In order to exclude undesired side reactions and ensure a consistent quality level, the process takes place in a fine vacuum (0.133 mbar). The reactor supplies a constantly high mixing quality with fill levels from 10 to 100%. A very high degree of residue emptying is achieved when changing products thanks to the patented SimConvex mixing tool, which has an outer contour with a sinusoidal shape. The mixing device is driven from above and is fully heatable. The shaft seals of the mixer shaft and the cutting rotor are face seals, and the sealing valve at the end of the mixing cone, which works without dead space, is gas tight. The mixing chamber is made of Hastelloy C22. — amixon GmbH, Paderborn, Germany
