Granted: 2009-12-08
Abstract: An apparatus and method for producing predetermined quantities of a meat product, inc which the apparatus comprises a twin vane concentric pump with an inlet and an outlet circumferentially spaced from one another, and a pair of independently movable vanes. During operation, one of the vanes is positioned between the inlet and outlet to permit pressurization of meat chunks in a chamber communicating with an outlet opening. The other vane is advanced toward the outlet with the outlet valve closed until a predetermined pressure is reached, at which point the outlet valve is opened to dispense a predetermined quantity of meat product. Similar to single vane meat pumps, the disclosed twin vane pump is capable of handling large meat chunks while causing relatively little damage to the chunks. However, the disclosed twin vane pump provides greater operating efficiency than single vane pumps and also achieves greater pressurization of the meat product than prior art pumps, permitting the meat product to be directly transferred to a stuffing horn without the need for further pressurization.

Filed: 2000-03-08
Granted: 2008-12-09
Abstract: L'invention concerne un sécheur ou un four à convection combinant infrarouge et air pour bandes continues en mouvement. Un ensemble volets (40) est prévu entre la source de rayonnement infrarouge (17) et la bande continue en mouvement pour exposer celle-ci de manière sélective au rayonnement infrarouge, et pour former une chambre (19) d'air hermétique en position fermée. Ce système permet d'obtenir un séchage amélioré de la bande continue et/ou de former un revêtement amélioré sur celle-ci à grande vitesse sans allongement concomitant de la longueur du sécheur. Lorsque l'atmosphère de séchage présente une concentration élevée de solvant, on évite d'exposer les éléments chauffants à cette atmosphère, ce qui pourrait provoquer des explosions, en actionnant les volets. Dans une forme de réalisation préférée de l'invention, des barres d'air sont utilisées pour soutenir de manière flottante la bande continue en mouvement de façon à éviter un contact entre celle-ci et des éléments du sécheur.
