ABSTRACT:
A dryer apparatus and method for drying yard waste or other particulate matter is disclosed. The dryer has a generally vertical housing defining an internal drying chamber. An input device may be positioned adjacent the housing top for transferring the particulate matter into the dryer. A discharge apparatus is positioned adjacent the housing bottom for discharging dried material out of the dryer. A plurality of generally horizontal transfer devices are vertically spaced apart within the internal drying chamber, defining a plurality of drying zones associated therewith. The transfer devices are adapted to transfer the particulate matter from one drying zone to a next lower drying zone. Additionally, when filling and transferring material from one zone to another, they provide a support on which the particulate matter may. A dryer is positioned proximate to the bottom of the housing for inputting drying air into the internal drying chamber and such that the drying air enters adjacent the bottom of the housing and is transmitted upwardly through the plurality of drying zones and particulate matter contained therein thereby drying the particulate matter.
