The invention relates to 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 and wherein a blade arrangement having at least one blade which is driven by a motor is disposed opposite the perforated plate so that the at least one blade passes over the nozzles in the perforated plate and in so doing cuts off granules of the emerging melt material. A housing is provided which is connected to the perforated plate and at least surrounds the at least one blade of the blade arrangement wherein a cooling medium flows through said housing so that the granules of melt material are solidified in the cooling medium which is introduced radially inwards or substantially radially inwards from outside all across the circumference from an inflow device formed by a separate inflow chamber which surrounds the circumference of the housing in the range of rotation of the at least one blade and from a circumferentially disposed inflow nozzle arrangement between the inflow chamber and the housing. A centripetal or at least substantially centripetal flow of the cooling medium is formed at least in the range of rotation and furthermore the cooling medium and the granules located therein are fed to an outlet in the housing wherein the cooling medium is a gaseous cooling medium.
