En este trabajo se estudian programas de secado artificial a temperaturas convencionales para madera aserrada de renovales de canelo Drimys winteri. El diseño experimental incluye el programa de secado (2) y el espesor de la madera (2). Seis ensayos de secado a la escala piloto son ejecutados en un horno convectivo de 0.3 m³. Se evalúa la calidad final de la madera, basándose en standarizaciones europeas, considerando la homogeneidad y el gradiente de humedad final, las tensiones de secado y el colapso, las grietas superficiales e internas. Los alabeos del secado se evalúan aplicando las normas chilenas. Los resultados muestran que los programas de secado que se estudian permiten secar satisfactoriamente los renovales de canelo. El comportamiento de los renovales frente al secado es condicionado por la calidad de la madera a secar y el contenido de humedad inicial de la madera verdeIn 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
