Abstract: 

Wood consists not only of water but also of polymers such as cellulose, hemicelluloses, and lignin. Drying of wood is a complex operation involving transient transfer of heat and mass along with several processes, such as physical or chemical transformations, which in turn, may cause changes in product quality. The drying of wood is an important step in the processing of timber. Little detailed data is available on different heating modes during drying of wood. This paper presents experimental work using convectional air drying, microwave drying, and infrared drying of Guilan spruce woods. The experimental results show drying time of the microwave heating is significantly reduced, while the strength stays higher than that obtained in convectional and infrared drying.
