Food extruder machine

Claim 2

A food extruder assembly including a food extruder comprising: a molding barrel; a core having an axis and a periphery and being fitted in the molding barrel, at least one of the molding barrel and core defining a plurality of axial passages spaced circumferentially about the core periphery, said core having a conical part at an end thereof; a die head positioned in facing relation to said cone part so as to define an annular clearance therebetween, said die head having a die hole communicating with said axial passages via said annular clearance; means for passing a main material through said passages to said annular clearance; and means for supplying a molten sub-material to said annular clearance for mixing with said main material, whereby the mixed main material and sub-material may be extruded through said die opening.

Claim 3

The food extruder assembly of claim 1 wherein said axial passages are defined by cooperation of said core and said molding barrel.

Claim 4

The food extruder assembly of claim 1 wherein said means for supplying a molten sub-material comprises a pump independent of said means for passing a main material.

Claim 5

A food extruder assembly including a plurality of food extruders arranged in a circle, each of which comprises: a molding barrel; a core having an axis and a periphery and being fitted in the molding barrel, at least one of the molding barrel and core defining a plurality of axial passages spaced circumferentially about the core periphery, said core having a conical part at an end thereof; a die head positioned in facing relation to said cone part so as to define an annular clearance therebetween, said die head having a die hole communicating with said axial passages via said annular clearance; means for passing a main material through said passages to said annular clearance, said means for passing a main material comprising a main material extruder device having a barrel arranged to pass through substantially the center of the circle, the axial passages of each of the food extruders communicating with said barrel for supplying the main material under pressure to said passages; and means for supplying a molten sub-material to said annular clearance for mixing with the main material, whereby the mixed main material and sub-material may be extruded through said die opening.

Claim 6

A food extruder assembly including a plurality of food extruders arranged in a circle, each of which comprises: a molding barrel; a core having an axis and a periphery and being fitted in the molding barrel, at least one of the molding barrel and core defining a plurality of axial passages spaced circumferentially about the core periphery, said core having a conical part at an end thereof; a die head positioned in facing relation to said cone part so as to define an annular clearance therebetween, said die head having a die hole communicating with said axial passages via said annular clearance; means for passing a main material through said passages to said annular clearance, said means for passing a main material comprising a main material extruder device having a barrel arranged to pass through substantially the center of the circle, the axial passages of each of the food extruders communicating with said barrel for supplying the main material under pressure to said passages; and means for supplying a molten sub-material to said annular clearance for mixing with the main material, whereby the mixed main material and sub-material may be extruded through said die opening.

Claim 7

A food extruder assembly including a food extruder comprising: a molding barrel; a core having an axis and a periphery and being fitted in the molding barrel, at least one of the molding barrel and core defining a plurality of axial passages spaced circumferentially about the core periphery, said core having a conical part at an end thereof; a die head positioned in facing relation to said cone part so as to define an annular clearance therebetween, said die head having a die hole communicating with said axial passages via said annular clearance; means for passing a main material through said passages to said annular clearance; means for supplying a molten sub-material to said annular clearance for mixing with said main material, whereby the mixed main material and sub-material may be extruded through said die opening; and core cooling means comprising a finned cooling fluid passage extending through said core.

Claim 8

A food extruder assembly including a food extruder comprising: a molding barrel; a core having an axis and a periphery and being fitted in the molding barrel, at least one of the molding barrel and core defining a plurality of axial passages spaced circumferentially about the core periphery, said core having a conical part at an end thereof; a die head positioned in facing relation to said cone part so as to define an annular clearance therebetween, said die head having a die hole communicating with said axial passages via said annular clearance; means for passing a main material through said passages to said annular clearance; means for supplying a molten sub-material to said annular clearance for mixing with said main material, whereby the mixed main material and sub-material may be extruded through said die opening; and core cooling means comprising a finned cooling fluid passage extending through said core.
