Food manufacturing apparatus and related method
View Patent ↗The invention is directed to a food manufacturing apparatus comprising a feed system for inputting a plurality of materials, an extruder and a cutting assembly. The extruder comprises a pump system and a rotating extrusion die removably connected to the pump system, wherein the rotating extrusion die comprises at least one product channel for receiving and extruding the plurality of materials. The cutting assembly comprises at least one groove and a wire attached through the groove. The feed system is attached to the extruder and the cutting assembly is located at a position to cut the extruded plurality of materials with the wire from the rotating extrusion die.
1. A food manufacturing apparatus for manufacturing food products by co-extrusion, the apparatus comprising:
an extruder assembly having an upper side and a bottom side, and including a rotating extruder die;
a feed system for inputting a plurality of materials, said feed system including at least two separate single mass feed assemblies extending in a transverse direction and being arranged one behind the other above said extruder assembly, wherein said extruder assembly receives single masses from said separate single mass feed assemblies on the upper side thereof and co-extrudes said single masses on the bottom side thereof with said rotating extruder die extending in a transverse direction and co-extruding the single masses at the bottom side in a downward direction;
said extruder die having an upper half formed with at least two separate single mass input channels and a lower half formed with at least two coaxial output channels;
said extruder assembly having at least two separate single mass product channels leading from said separate single mass feed assemblies to the upper side of said extruder die;
said extruder assembly including a pump system with separate pump assemblies disposed within said separate single mass product channels; and
a cutting assembly for cutting the co-extruded product streams extruded by said extruder die, said cutting assembly being disposed next to said extruder assembly and including a harp with a cutting portion disposed near the bottom side of said extruder die, said cutting portion of said harp being formed with at least one groove and having a wire running across said at least one groove.
2. The apparatus according to claim 1 , wherein said extruder die further comprises at least one cutting aperture.
3. The apparatus according to claim 2 , wherein said at least one cutting aperture of said extruder die corresponds in size with said at least one groove of said cutting portion of said harp of said cutting assembly.
4. The apparatus according to claim 1 , wherein said cutting assembly comprises a harp that is movable with a cutting portion thereof by a substantially vertical motion between a lower clear position and an upper cutting position.
5. The apparatus according to claim 1 , which further comprises a pivot stand supporting the apparatus.
6. The apparatus according to claim 1 , wherein said separate single mass feed assemblies are removably attached to said extruder assembly.
7. The apparatus according to claim 6 , wherein said separate single mass feed assemblies are open hoppers including driven feed rolls.
8. The apparatus according to claim 6 , wherein said separate single mass feed assemblies are open stainless steel hoppers.
9. The apparatus according to claim 6 , wherein said separate single mass feed assemblies are closed manifolds.
10. The apparatus according to claim 1 , wherein said separate pump assemblies extend in the transverse direction over an entire width of said extruder assembly and do not comprise intermediate bearings, plates, or other obstacles.
