Title
(EN) HIGH THERMAL TRANSFER HOLLOW CORE EXTRUSION SCREW ASSEMBLY
(FR) ENSEMBLE DE VIS D’EXTRUSION À CORPS CREUX À TRANSFERT THERMIQUE ÉLEVÉ
Abstract
(EN)
High thermal transfer, hollow core extrusion screws (50, 52, 124, 126, 190) include elongated hollow core shafts (54, 128, 130, 192) equipped with helical flighting (56, 132, 134, 194) along the lengths thereof. The flighting (132, 134, 194) may also be of hollow construction which communicates with the hollow core shafts (54, 128, 130, 192). Structure (88, 90) is provided for delivery of heat exchange media (e.g., steam) into the hollow core shafts (54, 128, 130, 192) and the hollow flighting (132, 134, 194). The flighting (56, 132, 134, 194) also includes a forward, reverse pitch section (64, 162, 216). The extrusion screws (50, 52, 124, 126, 190) are designed to be used as complemental pairs as a part of twin screw processing devices (20), and are designed to impart high levels of thermal energy into materials being processed in the devices (20), without adding additional moisture.
(FR)
La présente invention concerne des vis d’extrusion à corps creux, à transfert thermique élevé (50, 52, 124, 126, 190) comprennent des tiges à corps creux allongées (54, 128, 130, 192) équipés d’un filetage hélicoïdal (56, 132, 134, 194) le long des longueurs de celles-ci. Le filetage (132, 134, 194) peut également être de construction creuse qui communique avec les tiges à corps creux (54, 128, 130, 192). Une structure (88, 90) est disposée pour la distribution milieux d’échange de chaleur (par exemple, de la vapeur) dans les tiges à corps creux (54, 128, 130, 192) et le filetage creux (132, 134, 194). Le filetage (56, 132, 134, 194) comprend en outre une section à pas avant, inverse (64, 162, 216). Les vis d’extrusion (50, 52, 124, 126, 190) sont conçues pour être utilisées sous forme de paires complémentaires en tant que partie de dispositifs de traitement à deux vis (20), et sont conçues pour transférer des niveaux élevés d’énergie thermique dans des matériaux étant traités dans les dispositifs (20), sans ajouter de l’humidité supplémentaire.
