Wood Drying Kiln New Art
A wood drying kiln and airflow controlling process is described in which the kiln includes an structure with a charge receiving chamber, and a door accessible opening to allow passage of a charge of lumber for drying. Circulating fans in the structure produce airflow that is directed by baffles in a prescribed path through the charge. At least one row of elongated resilient brush bristles within the structure are positioned therein to yieldable engage the charge of lumber placed within the charge receiving chamber. The brush bristles are provided with sufficient density to limit passage of air laterally through the row.
Wood drying kilns are a faster alternative and more consistently controllable than air drying. Stacks of lumber may be effectively dried in just over two days, depending of course on the species of wood, initial moisture content, and other considerations that can affect drying time. On the other hand, air drying of the same material may take several months or more. Expediency is clearly an advantage in kiln drying over air drying, but need remains for efficient kiln systems that will provide for expeditious drying at low cost.
