  • Method and apparatus for manufacturing lignocellulosic materials with improved properties
    Patent number: 9273429
    Abstract: A method and apparatus for treating a wet or moist lignocellulosic material at a moisture content which is in a range from above the Xfsp value of the material down to about 0.1 kg water/kg dry below the Xfsp value, where Xfsp is the fiber saturation point value, with rapid warming of the wet or moist lignocellulosic material to a level that natural polymers in the lignocellulosic material soften, which changes the microstructure and results in improved properties of the lignocellulosic material.
    Type: Grant
    Filed: December 20, 2012
    Date of Patent: March 1, 2016
    Inventors: W. J. Murray Douglas, S. J. Hashemi
