Title:
UNIDIRECTIONAL MULTI-PATH LUMBER KILNS
Document Type and Number:
WIPO Patent Application WO/2014/150082
Kind Code:
A8
Abstract:
Embodiments provide a unidirectional multi-path kiln with two or more chambers and generally parallel flow paths extending through the kiln, on opposite sides, from charge entry portals at a first end of the kiln to charge exit portals at a second end of the kiln. Moist heated air flowing from the second heated chamber is received in the first chamber and circulated around the lumber charges with one or more fans. The lumber charges proceed in the same direction on the flow paths through the heated second chamber, which may be an existing kiln. Charge exit portals at the distal end of the kiln and/or intermediate charge portals between the second chamber and a third chamber may be provided with insulating members configured to reduce airflow from the second chamber through the charge exit portals.
