ResumenDuring the quality control of wood in the sawmills, drying represents the greatest detected problem. In fact, drying by air or in chambers it is an essential step in the wood processing because it is at this stage where more energy is consumed. It means important losses of raw material and expenses for the wood industry.
This work proposes an alternative solution to cracking and rupture of the cellular structure of the wood during the drying process. The proposed technique aims at the use of both, high-power ultrasound and infrared radiation, as non polluting alternative energies for drying wood pieces. The advantages of this system may represent an important economic decision for the lumber manufacturer increasing the production by reducing the drying times but keeping good quality.
