Patent

CA 2140489

A frozen dessert dispensing apparatus is provided with a metering chamber having a predetermined volume into which a frozen dessert product is issued at a uniform constant rate from a bulk source. The time period required to fill the chamber volume determines a characteristic viscosity valve of the dessert product which is advantageously used to time the flow of additional frozen dessert product from the source into and through the chamber to a selected point. The total time required to dispense a desired volume is based upon the viscosity measurement. A reciprocating piston arrangement provides gating of the frozen dessert product from the bulk source when in a first position and further acts to extrude frozen dessert product from the metering chamber when set in motion under the command of a controller. The piston arrangement includes a compressible plunger portion which deforms as necessary to prevent accidents or other mishaps from occurring in pinch-off regions of the apparatus.

Distributrice de desserts congelés dotée d'une chambre de dosage à volume prédéterminé distribuant un dessert congelé à un rythme constant à partir d'une source d'alimentation. Le temps requis pour remplir la chambre détermine la viscosité du dessert, et sert à mesurer la durée d'écoulement d'une quantité supplémentaire de dessert à partir de la source d'alimentation passant dans la chambre pour se rendre à un point donné. Le temps total requis pour distribuer la quantité voulue est fonction de la mesure de viscosité. Un piston alternatif empêche le dessert congelé de sortir de la source d'alimentation lorsque placé dans une première position, et extrude le dessert congelé à partir de la chambre de dosage lorsqu'il est mis en mouvement par un dispositif de commande. Le piston comprend un plongeur compressible qui se déforme selon les besoins pour prévenir les accidents dans les zones d'étranglement de la distributrice.
