Abstract
Official abstract text for this publication.
A gas assisted co-extrusion apparatus includes a co-extrusion die in communication with an extruder. A nozzle that is defined by a bore in the co-extrusion die extends about a nozzle axis to a nozzle exit of the co-extrusion die. An injector extends through the bore of the co-extrusion die along the nozzle axis. The injector and nozzle together form a dough into a rope that is tubular with a wall portion and an inner cavity surrounded by the wall portion as the dough is extruded out of the nozzle exit and about the injector. A compressed gas source provides a compressed gas out of an injector outlet and into the inner cavity of the rope to radially stretch the wall portion of the rope as the rope is dispersed from the injector. The co-extrusion die is spaced from the extruder to define a void therebetween. A delivery system delivers an entrainable material to the compressed gas in a pipe. The pipe is connected to an injector inlet of the injector in the void. This allows the pipe to operate within the ambient temperature of the environment and for the entrainable material to be entrained into the compressed gas prior to being introduced into the injector.
First claim
Opening claim text (preview).
What is claimed is: 1. A gas assisted co-extrusion apparatus for forming food products comprising: an extruder for producing a dough and having an extruder exit for a movement of the dough out said extruder; a co-extrusion die extending between a rear face and a front face and being in communication with said extruder for receiving the dough from said extruder; at least one nozzle defined by a bore in said co-extrusion die and extending about a nozzle axis to a nozzle exit at…
