A nozzle permits extrusion of an outer, expanded dough layer having two filler materials co-extruded therewith. An adjusting mechanism is provided for precisely locating two filler injection conduits with a surrounding guide nozzle. A pillow-shaped final product is formed, having an outer layer of expanded dough and two different filler materials. |

DETAILED DESCRIPTION The present invention teaches an apparatus for providing a co-extruded product, and also teaches a particular type of co-extruded product formed by the above-mentioned apparatus, wherein two different fillings are co-extruded within an outer expansible dough which expands uniformly upon extrusion.
The fillings do not expand significantly, and the extruded product is pinched and/or cut to form pillow-shaped articles.
The present invention includes a nozzle having an inlet portion for receiving a dough under pressure, the dough being an expansible dough when released to atmospheric pressure.
The nozzle has an outlet portion for the expansible dough, which surrounds a pair of tubes.
Each tube is adapted for injecting an edible material, such as jelly, peanut butter, fruit fillings, vegetable fillings, cheese fillings, and other fillings, inside the surrounding expansible dough.
The tubes extend completely through the nozzle body, and are adjustable by means of a plurality of set screws.
The resultant extrudate product is pinched and cut by a cutter to form pillow-shaped articles having an outer, expanded uniformly shaped layer, with a uniform cellular structure and two inner fillings.
The set screws permit adjustment of the pair of nozzles disposed within the outer casing, such that the inner fillings can be precisely centered and adjusted to provide the desired final product.
