A thin-layer reactor with several shafts is presented, for the continuous production of polymers for plastics or other liquid compounds to be degassed or gassed, having a housing (5), which surrounds a degassing space which can be connected to a negative-pressure or positive-pressure source and in which a plurality of axially parallel, intermeshing conveying shafts (4) are rotatably mounted. The conveying shafts are arranged in circular form around the degassing space and each conveying shaft meshes with the conveying shafts arranged on either side of it, so that thin layers of the material being treated, which can be degassed or gassed very well, form on the sides of the conveying shafts facing the degassing space. In the case of such an apparatus, driving the conveying shafts is achieved by an upper and/or lower planetary-gear extruder section (2, 3), the conveying shafts in the reactor space being frictionally connected to the planets (16) of the planetary-gear extruder section. Consequently, very simple sealing and good driving of the reactor conveying shafts is achieved. Since the rotating reactor conveying shafts also rotate simultaneously in the housing, there is also no need for the housing to turn. …<IMAGE>… |
