Abstract

L'invention concerne un mécanisme de séchage de papier isolant à changement de phase et un procédé de séchage de celui-ci. Le mécanisme de séchage comprend un corps de boîte de séchage, le corps de boîte de séchage étant relié au fond à une plateforme de séchage de pâte de bois. La plateforme de séchage de pâte de bois comprend une plaque (5) utilisée pour déposer une couche de pâte de bois. La plaque (5) est pourvue d'un trou d'évacuation d'eau (10) et est pourvue sur la face inférieure d'une plaque de pénétration d'eau constituée d'un matériau dur poreux. Le corps de boîte de séchage est également relié au fond à un mécanisme de piston de déshumidification ; un couvercle supérieur (1) est relié à une plaque d'évaporation (7) grâce à un châssis de support annulaire (16) et la surface de la plaque d'évaporation (7) est pourvue de plusieurs trous de refoulement d'air agencés en matrice ; le couvercle supérieur (1) est également relié à un mécanisme de chauffage, le mécanisme de chauffage comprenant plusieurs cylindres à air d'échange de chaleur (17), et les cylindres à air d'échange de chaleur (17) sont reliés à une buse d'entrée d'air (19) ; et une paroi latérale d'un châssis de raccord (2) est reliée à une buse de sortie d'air. Le mécanisme utilise une cavité avec une dépression, qui peut être pompée sous vide, et utilise le principe selon lequel le point d'ébullition de l'eau est inférieur avec une basse pression d'air pour amener l'eau dans la pulpe de bois à produire rapidement un changement de phase puis à s'évaporer grâce au pompage sous vide, ce qui présente les avantages d'un temps de séchage plus court, d'absence de tendance au roussissement et d'une meilleure uniformité de séchage.
