ABSTRACT:
A kiln system for drying green lumber to a predetermined moisture content according to the present invention includes a kiln chamber for enclosing a charge of lumber consisting of a number of laterally spaced rectangular solid stacks of lumber, a fan above the lumber for circulating air through the kiln chamber and through the lumber and a first elongate center bridging panel above the stacks of lumber and overlying each vertically extending air space defined between adjacent, laterally spaced stacks of lumber. The elongate center bridging panel includes a center portion having opposed side edges which extends laterally substantially across the air space. The center bridging panel also includes first and second side portions hingedly connected to the opposed edges of the center portion. The center bridging panel substantially prevents circulating air from rising above the stacks of lumber in the vertically extending air space. Accordingly, the circulating air is forced to flow through each successive stack of lumber to more evenly and efficiently dry the lumber.
