METHOD AND APPARATUS FOR STEAM HEATING WITH DRYING OF SOLVENTS

A method for drying wood based materials includes applying a treatment including a first chemical, such as a solvent, to a wood based material. The wood based material is preheated using steam. At least part of an atmosphere is evacuated from around the wood based material. The wood based material i...

Zusammenfassung:	A method for drying wood based materials includes applying a treatment including a first chemical, such as a solvent, to a wood based material. The wood based material is preheated using steam. At least part of an atmosphere is evacuated from around the wood based material. The wood based material is dried using heated using steam and is exposed to radiation to evaporate at least a portion of the first chemical. L'invention porte sur un procédé de séchage de matériaux à base de bois qui comprend l'application d'un traitement comprenant un premier produit chimique, tel qu'un solvant, à un matériau à base de bois. Le matériau à base de bois est préchauffé à l'aide de vapeur d'eau. Au moins une partie de l'atmosphère est évacuée de l'environnement du matériau à base de bois. Le matériau à base de bois, qui est séché à l'aide de vapeur d'eau chauffée, est exposé à un rayonnement pour faire évaporer au moins une partie du premier produit chimique.
