ABSTRACT:
A dryer is described, including elongated drying and steaming chambers through which wood to be dried travels. The wood is impinged with air and then steamed to a predetermined moisture content. Drying defects are minimized by humidity control, restraining devices to reduce warpage, and post-steaming of the wood for stress relief to reduce casehardening, checking, and collapse. The dryer is capable of adjusting to accept widely varying thicknesses of wood as well as long holdup times by the use of reversing switches on the drive to convey the wood through the dryer.
