Abstract
A mixing and degassing apparatus for viscous substances is provided with a distributor plate located above heat exchanger coils and joined for rotation with an agitator shaft. The distributor plate has the configuration of a truncated cone. The distributor plate can be of a single piece or step-like with at least one step. Its circumference is provided with recesses to provide sections having different radii. The sections with the larger radius extend to near the inner surface of a vessel wall and the sections with the smaller radius terminate above the coils. In the case of the step-like distributor piece, thin layers of the insulating material overlap between each step in the area of partitions, while simultaneously being effectively degassed.
