Abstract: A dry kiln, no matter how well equipped with controls, is only as efficient as the operator who runs it. Despite advances in control technology that give the operator more information than was possible in the past, it is still largely the operatorís judgment that determines whether a charge of lumber will go through the kiln in a minimum time, emerge uniformly dried to the desired moisture content, and be free of undesired drying defects and stresses. The operator determines what kiln schedule to use, and whether it should be a time or moisture content schedule. If kiln samples are to be used, whether manually or automatically weighed or monitored with probes, the kiln operator is still responsible for selecting representative kiln samples. The kiln operator must monitor the progress of drying, whether manually or with the assistance of computer readouts,and apply judgment in deciding if adjustments are necessary during drying. Also, the operator must apply judgment in determining when the lumber has reached final moisture content with a minimum of moisture content variation and apply any necessary equalizing or conditioning treatments.
