CA 2254764
Dryer, in particular for continuous sheet materials, comprising at least a surface which gives heat to the material (9) to be dried, formed by a metal plate or drum (7) heated by eddy currents induced by a rotating cylinder (1) arranged in proximity to such plate and outwardly covered with a plurality of permanent magnets (5). Thanks to this induction heating system, the dryer according to the present invention no longer needs conventional heating units, usually electrical resistance units or steaming units, which are complicated and hard to control.
L'invention concerne un sécheur, servant en particulier au séchage de matériaux en feuille continus, qui comprend au moins une surface qui transmet de la chaleur au matériau (9) à sécher et qui est formé par une plaque ou un tambour (7) métallique chauffés par des courants de Foucault induits par un cylindre rotatif (1) placé à proximité de ladite plaque et recouvert extérieurement d'une pluralité d'aimants permanents (5). Grâce à ce système de chauffage par induction, le sécheur selon la présente invention n'a plus besoin des unités de chauffage classiques, c'est-à-dire des unités à résistance électrique ou des unités à vapeur habituelles, lesquelles sont compliquées et difficiles à commander.
