Abstract: This invention relates to a process for producing granulated polymer materials from polymer solutions, in which organic solvent of the polymer solution is evaporated in a heat exchanger, optionally with the admixture of steam, or in a holding tube with the admixture of steam, and the paste-like mixture of concentrated solution, solvent vapour and optionally of condensed steam is separated in a separator provided with rotating built-in components for cleaning off the walls. The pre-concentrated polymer solution is further concentrated in the separator by supplying heat by way of heating the separator walls or the rotating built-in components and by the shearing energy of the rotating built-in components.Residual degassing of the solvent is effected before granulation, e.g. in the discharge extruder of the separator which is provided with rotating built-in components, through one or more degassing zones, optionally by the additional admixture of entraining media, such as inert gas or steam, for example.

Abstract: In a multi-shaft worm machine comprising a plurality of worm shafts rotating in the same or in opposite directions, at least one worm fitting (6) is positively connected to the associated worm shaft (3), while a countertwisting element (7) is supported in a freely rotatable manner on the opposing worm shaft portion and is driven in the opposite direction of rotation by the worm shaft (3) of the positively connected worm fitting 6.
