Abstract
A method for drying wood based materials includes applying a treatment including a first chemical, such as a solvent, to a wood based material. At least part of an atmosphere is evacuated from around the wood based material. The wood based material is exposed to electromagnetic radiation to evaporate at least a portion of the first chemical.
Claims29
A method comprising:
- applying a treatment including a first chemical to a wood based material;
- evacuating at least part of an atmosphere from around the wood based material;
- and
- exposing the treated wood based material to electromagnetic radiation, wherein at least a portion of the first chemical is evaporated and at least a portion of the treatment remains with the wood based material.
1 more element
A method comprising:
- permeating a wood based material with a treatment including a first chemical, and the treatment penetrates beyond the surface of the wood based material;
- uniformly heating the wood based material with electromagnetic radiation, wherein at least a portion of the first chemical is evaporated and at least a portion of the treatment remains with the wood based material;
- and
- substantially preventing combustion of at least the first chemical.
1 more element
An apparatus comprising:
- at least one chamber sized and shaped to receive a wood based material;
- means for uniformly drying the wood based material coupled to the at least one chamber, wherein the wood based material includes a treatment having at least a first chemical, and the means evaporates at least the first chemical and leaves a portion of the treatment with the wood based material;
- and
- means for substantially preventing combustion of at least the first chemical.
