En este trabajo se estudia experimentalmente la velocidad del secado artificial a temperaturas convencionales de renovales de canelo Drimys winteri. El diseño experimental incluye los programas de secado y el espesor de la madera. Seis ensayos son realizados usando madera de 25 y 50 mm de espesor, en un horno convectivo de 0.3 m³. La madera para los ensayos experimentales proviene de bosques de renovales creciendo en la zona de Lanco (X Región, Chile). Los resultados muestran que la velocidad del secado es limitada por la tendencia a los defectos del secado de los renovales de canelo. Las curvas de secado carecen de la etapa de velocidad de secado constante, la velocidad de secado máxima se encuentra en el rango de 1.72 x10-2 y 2.99x10-2 (%/h) y el contenido de humedad crítico varía entre 87 y 116 %This is an experimental study at conventional temperatures of the wood drying rate of canelo Drimys winteri regrowth. The experimental design include as a variables the drying schedule and the wood thickness. Six run are realized in 25 and 50 mm of wood thickness using a pilot drier with 0.3 m³ capacity. Canelo regrowth from Lanco (X Region, Chile) are utilized in this experiments. The results show that the wood drying rate is conditioned by the drying defects tendency of canelo regrowth. Also the drying curves are not constant drying rate and they have a maximal drying rate between 1.72 x10-2 and 2.99x10-2 (%/h) and the critical moisture content are among 87 and 116 %
