  6. 4. Controlling microwave heating and its effect on the properties of wood

    Author : Lars Hansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

    Abstract : Drying wood with microwave energy is not so common, but could be a complement to conventional air circulation drying due to the possibility of drying wood faster than with conventional drying methods with preserved quality. An industrial-scale, on-line microwave drier for wood components is under development at the Division of Wood Physics. READ MORE
