摘要

In order to efficiently dry the internal check-prone poplar (Populus nigra) lumber, the 50 mm-thick lumber, freshly cut from Taleghan forest in Iran were dried using three different conventional kiln drying schedules (T8-F4, T8-F5 and T9-F4). The initial dry-bulb temperatures for the schedules were adjusted at 54, 54 and 60 deg C, while the final dry-bulb temperatures were 82, 82 and 71 deg C, respectively. After drying, the severity of surface and internal checking in the dried lumber was determinedand then the statistical process control (SPC) was applied to monitor the dried lumber quality. Based on the SPC results, the quality of lumber dried by all the three drying schedules was satisfactory; however, the T9-F4 schedule resulted in lower internal checking compared to the other schedules, probably due to a greater stress relief treatment time.
