Abstract

a. L'invention concerne un dispositif pour le chauffage diélectrique continu à l'aide d'une énergie hyperfréquence; b. Ce dispositif est caractérisé par le fait qu'au moins un élément d'accord ou d'adaptation est agencé pour pénétrer dans le dispositif servant à amener l'énergie d'un générateur micro-ondes à la chambre de traitement et réalise sous la forme d'un guide d'ondes, que cet élément d'accord est guidé de manière à pouvoir être déplacé dans un perçage ménagé dans la paroi du guide d'ondes, que le perçage forme sur une longueur de lambda /4 à partir du plan de la paroi intérieure du guide d'ondes, une fente isolante avec l'élément d'accord que le perçage présente, à une distance de lambda /4 de ladite paroi intérieure un élargissement de sa section transversale ayant une longueur de lambda /4 et auquel se raccorde un rétrécissement de la section transversale; c. Application au chauffage de produits extrudés en continu.
