Method and apparatus for manufacturing lignocellulosic materials with improved properties |
| 摘要 |
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. |

1. A method of treating a wet or moist lignocellulosic material at a moisture content in a range from above the Xfsp value of the lignocellulosic material down to about 0.1 kg water/kg dry below the Xfsp value, where Xfsp is the lignocellulosic material fibre saturation point, comprising the step of rapid warming the material so that the temperature of lignocellulosic material is brought up thereby changing the micropore structure of the material improving the properties of the lignocellulosic material. |
