SANDOVAL, S; RODRIGUEZ, J; MENDEZ, L  e  FUENTES, M. Effect of Temperature and Airflow on the Drying Process of Oak Wood (Quercus Candicans Neé), Pretreated with Water. Inf. tecnol. [online]. 2004, vol.15, n.1, pp.11-16. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642004000100002.

To study and analyze the drying process of hardwood, experiments drying tunnel experiments of Red Oak wood (Quercus Candicans Neé) from the North Mountains (Sierra Norte) in Oaxaca State (Mexico), were performed. The wood to be treated had an average initial moisture content of 62.93% and two drying schedules were employed: an intense at temperatures between 47 and 71oC and a mild one at temperatures between 37 and 48oC, both schedules done at two airflows (1.073 m/s and 1.64 m/s). Thirty-two planks were pretreated with cool water before to be drying. The quality of wood was measurement quantifying the level of defects (warpage, splittings, checkings, kink, bow and crook) generated by each drying schedule. It was founded that the mild temperature schedule generates less defects.
