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.
Claims12
A device for drying granules, comprising:
- a. a housing comprising:
- (i) a granule-process fluid inlet;
- (ii) a granule outlet;
- (iii) a fluid outlet;
- and
- (iv) a fan wheel air outlet;
- b. a rotor comprising:
- (i) a hollow shaft with a plurality of rotor holes;
- (ii) at least one rotor blade;
- and
- (iii) at least one sieve encompassing the outside of the rotor, having sieve openings of a size smaller than the granules;
- and
- c. a fan wheel;
- and
- wherein the at least one rotor blade imparts a direction of movement to granules and to a process fluid respectively, such that the process fluid can be separated from the granules, and further wherein the fan wheel draws air into the hollow shaft via the granule outlet and the plurality of rotor holes and the air is evacuated through the fan wheel air outlet.
