Abstract
Kiln design that uses a series of at least two subsections with airflow in constant but alternating directions instead of using bi-directional fans that periodically reverse directions. The uninterrupted alternating air flow may be used in continuous drying kilns (CDK) with two sets of carriages carrying spaced stacks of lumber travel in opposite directions through a sequence of chambers. The uninterrupted alternating air flow may be used with a set of at least one pathway for carriages carrying lumber to be dried where all carriages move from a first end of the kiln to a second end of the kiln.
