Abstract

In order to adjust kiln drying conditions for HORNBEAM (carpinus betulus L.) lumber with 7.5 cm THICKNESS in a way that the lumber's quality is preserved, a, drying down to the final moisture content of 8±2% was carried out through three schedules designated as T3-B1 (general acronym of FPL for Ulmus crassifolia), T3-B2 , T4-B2. The initial dry bulb temperatures were adjusted to 44, 43 & 44oC for three schedules, respectively, and the final dry bulb temperatures were set to 71, 71 & 82oC, respectively. Duncan test showed that there was no significant difference between the THICKNESSes of three charges, which had been commercially cut, at 99% confidence limit. The THICKNESS of 95.4% of the lumber used in the test was measured and it was found that the THICKNESS range is between 72 mm and 78 mm. Therefore, this research recommends adjusting the schedule at 75 mm for drying the lumber. The warp, including bow, crook and twist of lumber, were examined in all stages of drying, and analyzing the results through quality control diagrams prepared by the Excel software program showed first and third schedules fall within the favorable quality control range as compared to the second schedule. However, the third schedule produces results with more consistency relative to the first schedule. Therefore, T4-B2 (FPL) is the best schedule for drying lumber of carpinus betulus with a THICKNESS of 75 mm. CONDITIONING for 24-40 hours is recommended if reducing internal stresses is required.
