Abstract
The invention relates to a chain of modules constructed to sequentially dry plastic particles each module comprises a mixing chamber having a trough formed therein, the trough having side walls inclined to the horizontal and a slot extending along the bottom thereof. The slot is covered by a grating to permit passage of air into the mixing chamber but to prevent particulate material from falling out of the trough through the slot. A pressure chamber is constructed immediately below the trough in the body portion of the module and means, are provided for delivering air to the pressure chamber thereby causing a stream of air to be forced upward into the mixing chamber through the slot in the trough. Each module is tilted to provide a flow of plastic particles through the trough.
