Improved cooking devices and methods of achieving intimate heat transfer contact between a low-friction, non-stick release sheet material and a heated platen are provided. In particular, improved intimate heat transfer contact may be achieved by providing a very thin release sheet, providing a layer of heat transfer enhancing material forming an intimate heat transfer contact interface between the release sheet and the platen, and/or providing a release sheet that is gas-permeable and liquid-impermeable. A dynamic tensioning system is also provided for mounting a release sheet to a heated platen and maintaining even, bidirectional tension on the release sheet to keep it taut against the platen. Illustrated embodiments of the invention include a clamshell grill and conveyorized contact toaster.

L'invention concerne des dispositifs de cuisson améliorés et des procédés permettant d'obtenir un contact de transfert thermique intime entre un matériau de pellicule de protection non adhérente, à faible friction, et une plaque chauffée. En particulier, un contact de transfert thermique intime amélioré peut être obtenu par fourniture d'une pellicule de protection très mince, fourniture d'une couche de matériau améliorant le transfert thermique formant une interface de contact de transfert thermique intime entre la pellicule de protection et la plaque, et/ou fourniture d'une pellicule de protection qui est perméable aux gaz et imperméable aux liquides. Un système de tension dynamique est également prévu pour monter une pellicule de protection sur une plaque chauffée et maintenir une tension uniforme, bidirectionnelle, sur la pellicule de protection pour la maintenir raide contre la plaque. Des modes de réalisation illustrés de l'invention comprennent une grille double coque et un grille-pain de contact à convoyeur.
