ABSTRACT:
A method and apparatus for drying material, especially wood particles, having moisture therein, comprising depositing the material to a selected depth onto a transport conveyor at the first end of a drying chamber. Heat is applied to the material as it is transported toward the opposite second end of the drying chamber so that, adjacent the second end, the material forms essentially two layers, a first layer having a first level of moisture therein and a second layer having a second level of moisture therein which is different from the moisture content of the first layer. Means are provided adjacent the second end for removing the second layer, which has the desired moisture, from the conveyor and directing that layer exteriorly of the chamber. The first layer, which has a remaining moisture content greater than the first layer, may be further dried to achieve the desired moisture content.
