    • An apparatus is disclosed for producing granules or pastils from a flowable material of varying viscosity wherein material is supplied to a pressing nip between a rotating hollow roll (1) having internal teeth and an externally toothed ejection roll (2) in engagement with said hollow roll. Provided in the hollow roll (1) are bores (5) which extend from the respective teeth bottoms of the internal toothing to the outer side of the hollow roll (1) and through which the material is expelled on engagement of the ejection roll (2) and deposited in the form of pastils or granules on a cooling surface (13). On the outer periphery of the hollow roll (1) a jacket tube (3) may be positioned the jacket tube having bores which align with the bores (5) of the hollow roll (1), the jacket bores also having a reduced cross-section compared with the bores of the hollow roll to permit adaption of the apparatus to the viscosity of the flowable material to be processed. The end faces of the hollow roll (1) may be closed by end plates (1a), (1b) of which at least one has a hollow center bore (12) through which a hollow tube (15) for supplying the material extends in sealed manner, the hollow tube (15) comprising exit openings lying in the interior of the hollow roll (1) for the exit of the flowable material. Secured to the hollow tube (15) are holders (14), at the free ends of which the ejection roll (2) is mounted freely rotatably.
