Abstract
Abstract An extrusion device for forming and shaping food product to a chosen cross section area and shape such as the filling for Chinese egg rolls, the product requiring mild compressive action for proper binding, and wherein mild shear forces acting on the product are effective to cause separation, breakup and damage. The apparatus comprises a housing with means for forcing the food product through the housing and in which the housing contains means defining a first section receiving a flow of the food product which initially shapes the flow into a predetermined shape and cross section, followed by a stabilizing section smoothly continuously transitioning from the first section and which has an outlet whose dimensions transverse to the longitudinal direction of movement of the product do not increase. By combining the first section with the stabilizing section food product is first shaped and then gently handled so that it binds together properly. The means in the housing may comprise an insert retained in the housing by thumb screws which insert may be open on one side which contacts a wall of the housing thus allowing for easy disassembly and cleaning.

In an extrusion device for forming and shaping food product to a chosen cross section area and shape, the product requiring mild compressive action for proper binding, and wherein mild shear forces acting on said product are effective to cause separation, breakup and damage to said product affecting said proper binding, said device include a housing and means for forcing such food product through said housing, means in said housing which comprises, means defining a first section having an inlet receiving a flow of food product forced into said housing by said forcing means and having an exit region of a first predetermined cross section area and shape, said first section means initially shaping the cross section of said flow to conform to said first predetermined cross section area and shape, and means defining a stabilizing section having an inlet smoothly continuously transitioning from the exit region of said first section and having an outlet of second cross section area and shape corresponding to said chosen cross section area and shape for said food product, said inlet of said stabilizing section having a cross section corresponding to said first cross section area and shape, whereby said food product exits said first section and smoothly enters said stabilizing section, said first cross section area being up to about 15% greater than said second cross section area at said outlet, and said stabilizing section comprising a defined longitudinal passage whose dimensions transverse to the longitudinal direction of said passage do not increase from said inlet of said stabilizing section to said outlet, whereby said first section delivers said product to said stabilizing section as a continuous even flow and alters the cross section of flow of said food product from said first predetermined cross section area and shape to said chosen cross section area and shape as said product passes through said stabilizing section to said outlet and proper binding of said product is effected.
