Abstract
A device and method for cooling granules, in particular wax granules, for processing in an injection-moulding machine, which has a cavity for receiving the granules and having an inlet opening and an outlet opening, and at least one further opening is provided for supplying a gaseous medium. In the device of the invention, the outlet opening is arranged directly or indirectly at the feed region of the screw of an injection-moulding machine and the cavity is connected to a cold-gas production device. In the process of the invention, the inlet temperature and the outlet temperature of the gas is determined and by determining the temperature difference, the preset theoretical temperature in the cavity is controlled and/or regulated.
