Pilot Drying Test on Eucalyptus citriodora Plantation Wood

Results of a pilot drying test conducted in a trial with 60m<3> of wood using a conventional drying kiln in a Beijing wood processing plant. Results showed that a laboratory optimized drying schedule could be used for drying of 25mm thickness Eucalyptus citriodora plantation wood. The drying quality based on visible defect factors and final moisture content after drying of 8.5% met the National Sawn-timber Drying Quality Standard second grade requirement, and the average moisture content difference through the wood cross-section of 1.9% met first grade requirement. The drying stress index of 3.8%, nearly met the National Sawn-timber Drying Quality Standard second grade requirement (3.5%). This result would suggest that in the practical drying of E. citriodora plantation wood, a longer high-humidity stabilisation period is needed. The main drying deformation defects of E. citriodora plantation wood observed in pilot drying was cupping, bowing and twisting. To reduce drying deformation, it is suggested that in the practical drying on E. citriodora plantation wood, some measures such as selecting the wood with pith or close to pith for separate drying, decreasing the stickers space and heavy stack top-loading methods should be considered.
