Abstract

An apparatus and method for extruding extrudate through an extruding horn having a geometry that allows for a uniform flow from the discharge end into a cooking section that sets the outer surfaces of continuous flow of all meat specie. The technology as disclosed and claimed allows for uniform product thickness throughout the cooking process, increased system throughput, and increased bind in the sheet leading to overall increased product yields. The technology eliminates the need for a meat press ahead of the system to set thickness further reducing yields.

First claim

What is claimed is:

1. A method of extruding extrudate through an extrusion horn comprising:
extruding an extrudate through a conduit communicably extending between an entry portal and an exit portal, by extruding the extrudate through a feeder conduit portion of the conduit communicably extending from the entry portal and communicably contacting with an in-line end-to-end relationship to a tapered portion communicably extending to the exit portal, and further extruding the extrudate through the tapered portion,
where the tapered portion of the conduit has an outwardly tapered end and an inwardly tapered end where the outwardly tapered end is disposed at an upstream position with respect to the inwardly tapered end thereby providing back pressure against the extrudate to improve uniform flow, and where the tapered portion is configured as a heating element, and thereby searing the extrudate as the extrudate flows through the tapered portion.

2. The method for extruding extrudate as recited in claim 1 , where the inwardly tapered end of the conduit has one of a non-stick coating and a non-stick surface applied for searing the product flowing there through.

3. The method for extruding extrudate as recited in claim 2 , where the non-stick coating is one or more of a polytetrafluoroethylene (PTFE) coating, a ceramic coating, a silicone coating and an enameled cast iron coating.

4. The method for extruding extrudate as recited in claim 2 , where the non-stick surface is one or more of a highly polished stainless steel surface, an anodized aluminum surface and a seasoned cast iron surface.

5. The method for extruding extrudate as recited in claim 1 , comprising:
applying a non-stick coated fabric over an inner wall of the inwardly tapered end of the conduit.
