GAS ASSISTED CO-EXTRUSSION APPARATUS AND PROCESS FOR FORMING FOODS

A gas assisted co-extrusion apparatus (20) includes a co-extrusion die (22) in communication with an extruder (24). A nozzle (56) that is defined by a bore (58) in the co-extrusion die extends about a nozzle axis (AN) to a nozzle exit (60) of the co-extrusion die. An injector (50) extends through th...

Zusammenfassung:	A gas assisted co-extrusion apparatus (20) includes a co-extrusion die (22) in communication with an extruder (24). A nozzle (56) that is defined by a bore (58) in the co-extrusion die extends about a nozzle axis (AN) to a nozzle exit (60) of the co-extrusion die. An injector (50) extends through the bore of the co-extrusion die along the nozzle axis. The injector and nozzle together form a dough (26) into a rope (30) that is tubular with a wall portion (32) and an inner cavity (34) surrounded by the wall portion as the dough is extruded out of the nozzle exit and about the injector. A compressed gas source (62) provides a compressed gas out of an injector outlet (66) and into the inner cavity of the rope to radially stretch the wall portion of the rope. A delivery system (86) delivers an entrainable material to the compressed gas in a pipe (78) connected to an injector inlet. Un aparato de co-extrusión asistido con gas (20) incluye un molde de co-extrusión (22) en comunicación con un extrusor (24). Una boquilla (56) que se define por un orificio (58) en el molde de co-extrusión se extiende alrededor de un eje de boquilla (AN) a una salida de boquilla (60) del molde de co-extrusión. Un inyector (50) se extiende a través del orificio del molde de co-extrusión a lo largo del eje de boquilla. El inyector y la boquilla conjuntamente forman una masa (26) en una cuerda (30) que es tubular con una porción de pared (32) y una cavidad interior (34) circundada por la porción de pared a medida que la masa es extruida fuera de la salida de boquilla y alrededor del inyector. Una fuente de gas comprimido (62) proporciona un gas comprimido afuera de una salida de inyector (66) y en la cavidad interior de la cuerda para estirar radialmente la porción de pared de la cuerda. Un sistema de suministro (86) suministra un material arrastrable al gas comprimido en una tubería (78) conectada a una entrada de inyector.
