Abstract: A device for drying granules, such as those made from a plastic material. The device can have a spiral arrangement of rotor blades on a rotor to propel process fluid through a sieve and separate the process fluid from granules by having sieve openings of a size smaller than the granules. The device can also have a fan wheel and a hollow shaft to create an air flow and improve separation and drying of granules. The device enables reliable automated drying of granules using less energy than prior art devices.
