Abstract

A method for producing pharmaceutical products from a melt material, wherein the melt material emerges from nozzles in a perforated plate, and is then granulated. A motor-driven cutter arrangement having at least one blade is opposite the perforated plate so that it cuts pellets emerging from nozzles in the perforated plate. A gaseous coolant flows through a housing which adjoins the perforated plate and encloses the at least one blade. The pellets of the melt material are then solidified in the coolant. Coolant is introduced from a separate inlet chamber that circumferentially encloses the housing in the area of rotation and from an inlet nozzle arrangement extending circumferentially between the inlet chamber and the housing. Coolant is introduced circumferentially from all sides essentially radially inward. A substantially centripetal flow of the coolant is produced in the area of rotation, and the coolant and pellets are conveyed to an outlet.
