Resumen o descripción
In the West Sierra Madre region of Durango red oak is a species that has traditionally been considered useless due to difficulties in the drying and sawing processes. This work presents the evaluation of a heat pump dryer as an alternative to the commonly used high temperature kiln. An existing refrigeration system was adapted to investigate red oak drying at laboratory scale. The system accommodates 90 wood pieces (1 v.;" thick x 2 Y," wide x 24" long) in an arrangement which simulates the flow through one of the typical flow passages of a conventional wood pack prepared for conventional drying. The investigated variable was the drying chamber air inlet temperature at two levels of air superficial velocity through the samples. Results evaluation showed that the use of air inlet temperatures above 40-45 'c tend to produce wood of bad quality, while temperatures below 30°C lead to excessive drying times. A preliminary design of a medium sized drying system and a comparison of its perfonllance with that of a conventional system resulted in a competitive product pncc.
