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.
