Abstract
Abstract An extruder provides three materials, one co-extruded about the other. A first material is completely enrobed by a second material, which in turn is completely enrobed by a third material. The first and third materials are preferably cookie doughs having differing compositions, the first material forming the core and having a moist and chewy texture upon baking. The third material is preferably a cookie dough having a relatively crispy texture upon baking. The second material serves as a moisture barrier and to prevent bleeding between the first and the third materials. The second material may be composed of, for example, an oil-based fluidic material or a gel.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
229 words
An extrusion apparatus for co-extruding three streams simultaneously and having three generally concentric flow passages defined by a die, said die comprising: three plates in face abutting relationship, a first of said plates being a block attached to means for extruding two materials, said block defining two side-by-side apertures, each being in communication with said means for extruding, an extrusion nozzle defining a generally cylindrical internal axial passage and a second annular orifice concentric with said passage, said nozzle having an internal sleeve member inserted within and radially spaced from a conical member to form both the internal passage and said annular passage with said conical member having a conduit fixed thereto and radially extending from the exterior of said conical member and in communication with said annular passage, a second plate abutting with said first of said plates, said conical member abutting said first of said plates such that a flow passage is defined by said internal axial passage communicating with a first of said apertures, a second of said apertures communicating with an aperture defined by said second plate and surrounding said nozzle, a third of said plates defining an extrusion orifice for the three streams, the second of said plates defining an opening extending generally parallel to a face of said plates through which said radially extending conduit projects for communication with a third extrusion means.
