This wood products note highlights a case study involving the kiln drying of 4/4 eastern white pine (Pinus strobus) from the mountains of North Carolina. The study was designed to determine the effects three different handling and storage procedures prior to kiln drying have on the severity of brown stain in the kiln dried lumber. Kiln drying very soon after sawing the log was the only procedure to prevent brown stain.
This wood products note highlights a case study involving drying 4/4 pine boards in a conventional track kiln where a fan went out during the cycle. Airflow measurements and ending moisture content figures are shown by location within the kiln. General comments are made concerning what to do and what to expect when one or more fans do go out during a drying charge.
This wood products note offers suggestions to help furniture manufacturers reduce or prevent the problem of veneer checking.
Properly kiln dried lumber stored, dead packed in an enclosed, unheated shed may pick up moisture. Redrying may be necessary. Drying stresses do develop during redrying and should be relieved.
