ABSTRACT:
A cooling device for cooling plastic particles includes a casing having a hub extended upward from an inner and lower portion for forming an annular chamber between the casing and the hub. A water is supplied into the annular chamber for moving the plastic particles upward and out through the hub, such that the plastic particles may be cooled by the water. A housing is secured on top of the casing and a pipe is coupled to the housing for supplying the plastic particles into the housing and for cooling the plastic particles in the housing by the air flowing into the housing.
