Abstract

PEREZ, Patricio; ANANIAS, Rubén A  and  HERNANDEZ, Gonzalo. WOOD DRYING STUDY OF CANELO DRIMYS WINTERI RE-GROWTHS. Maderas, Cienc. tecnol. [online]. 2007, vol.9, n.1, pp.59-70. ISSN 0718-221X.  http://dx.doi.org/10.4067/S0718-221X2007000100005.

In this paper the wood drying schedules at conventional temperatures of Drimys winteri re-growths are studied. The experimental design includes as variables the drying schedules (2) and the wood thickness (2). Six drying runs at pilot scale are performed in a 0.3 m3 capacity laboratory dry kiln. The wood drying quality, being based on European standards is evaluated, considering moisture homogeneity, moisture gradient, casehardening, collapse, surface and internal checking. The drying defects are evaluated applying Chilean standards. The results show that the proposed drying schedules allow a satisfactory drying of canelo re-growths. The behaviour of the canelo re-growths during the drying are conditioned by the wood quality before the drying, and the initial moisture content

Keywords : Kiln drying; drying schedules; drying quality; drimys winteri.
