Abstract

A method for the continuous production of cookies having a high content of large inclusions, such as chocolate chips, nuts, and fruit pieces includes extruding a cookie dough containing the inclusions through a die orifice to obtain an extrudate dough rope, and cutting the extrudate dough rope with an ultrasonic cutting blade. The ultrasonic cutting severs the extrudate dough rope into dough pieces which fall onto a moving conveyer into a substantially uniform or regular array for uniform baking. The ultrasonic cutter is controlled to provide a roughened top surface on a dough piece to provide a home baked appearance upon baking, while cutting through the inclusions without substantial displacement of the inclusions which would cause pock marks on the surface of the dough piece, and without substantial dough piece weight variation.

First claim

What is claimed is:

1. Apparatus for the continuous production of cookies having a high content of large inclusions comprising a wirecut machine having a plurality of die orifices, a plurality of ultrasonic cutters which are each attached to the wire cut machine and which each have an ultrasonic cutting blade, and a conveyor belt located below the wirecut machine, wherein the ultrasonic cutting blades travel in a looped path and are synchronized to cut across a plurality of die apertures which are above the moving conveyor to ultrasonically cut vertically oriented dough ropes extruded from the plurality of die apertures to obtain dough pieces which fall onto the moving conveyor in a substantially uniform array of rows, each of the ultrasonic cutters being configured to provide the ultrasonic cutting blades with an amplitude of blade motion which is 12 microns to 18 microns.

2. Apparatus for the continuous production of cookies as claimed in claim 1 wherein each blade has its own ultrasonic components comprising an ultrasonic power supply, converter, and booster, so that the amplitude of each blade may be adjusted independently.

3. Apparatus for the continuous production of cookies as claimed in claim 2 wherein the plurality of ultrasonic cutters are journaled or connected together or mounted or attached to a single reciprocating mechanism to synchronize their movement for cutting a plurality of at least substantially vertically oriented extrudate dough ropes so that all of the blades contact and cut one or a plurality of different extrudate ropes at least substantially simultaneously so that the cut dough pieces fall in an at least substantially uniform straight row across the oven band.

4. Apparatus for the continuous production of cookies as claimed in claim 2 having a power supply to said ultrasonic cutting blades which is varied to produce surface roughness on the dough pieces.

5. Apparatus for the continuous production of cookies as claimed in claim 2 wherein each of the ultrasonic cutting blades is mounted to a booster and the booster varies the amplitude of said ultrasonic cutting as the blade cuts across the dough rope to provide a roughened top surface on the dough piece.

6. Apparatus for the continuous production of cookies as claimed in claim 2 where the ultrasonic cutting blades are half wave guillotine, half wave edge guillotine, full wave guillotine, or full wave wedge guillotine cutting blades.

7. Apparatus for the continuous production of cookies as claimed in claim 6 having 3 or 4 ultrasonic cutting blades across the oven band.

8. Apparatus for the continuous production of cookies as claimed in claim 2 wherein each ultrasonic cutter is mounted on the wirecutter so that the cutting of the dough rope occurs in the same direction that the underlying conveyor belt and cut dough pieces thereon are moving.

9. Apparatus for the continuous production of cookies as claimed in claim 2 wherein each ultrasonic cutter is mounted on the wirecutter so that the cutting of the dough rope occurs in the direction opposite to the movement of the underlying conveyor belt and cut dough pieces which have fallen upon the conveyor.

10. Apparatus for the continuous production of cookies as claimed in claim 2 wherein each blade cuts upwards towards a die aperture and then cuts downward away from the die aperture, at about 60% to about 90% across the maximum width, thickness, or diameter of the die aperture.

11. Apparatus for the continuous production of cookies as claimed in claim 10 wherein upon cutting the dough rope the top edge of each blade is at a distance of less than about 20/1000 inches from the die aperture.

12. Apparatus for the continuous production of cookies as claimed in claim 2 wherein each die aperture comprises a plurality of alternating concave, convex, and linear portions or sections of varying length, the concave and convex curved portions having different radii of curvature or differently shaped arcs.

13. Apparatus for the continuous production of cookies as claimed in claim 1 further comprising a die insert for each die aperture, the die insert having a circular input end which fits into a circular die orifice or aperture of the wirecutter, and an opposing output end which contains an irregularly shaped curvilinear die exit aperture, the die insert having an inner passageway which tapers inwardly or narrows from the circular input end to the irregular output end so as to compress the dough and conform it to the irregular shape of the die exit aperture.

14. Apparatus for the continuous production of cookies as claimed in claim 13 wherein the die exit aperture of the die insert comprises a plurality of alternating concave, convex, and linear portions or sections of varying length, the concave and convex curved portions having different radii of curvature or differently shaped arcs.

15. Apparatus for the continuous production of cookies as claimed in claim 1 further comprising a linear air nozzle or air knife for each ultrasonic cutting blade which provides a curtain of air to the ultrasonic cutting blade surfaces.

16. Apparatus for the continuous production of cookies as claimed in claim 15 wherein the linear air nozzle or air knife is mounted on the wirecutter, underneath and upstream of the die orifice in a fixed position over each of the ultrasonic blades.

17. Apparatus for the continuous production of cookies as claimed in claim 1 wherein each blade has its own ultrasonic power supply, and the power supply to each ultrasonic cutting blade is varied to lower the power supply input and increase friction during cutting as the blade travels across the dough rope to produce surface roughness on the dough pieces.

18. Apparatus for the continuous production of cookies having a high content of large inclusions comprising a wirecut machine having a plurality of die orifices, a plurality of ultrasonic cutters which are each attached to the wire cut machine and which each have an ultrasonic cutting blade, and a conveyor belt located below the wirecut machine, wherein the ultrasonic cutting blades travel in a looped path and are synchronized to cut across a plurality of die apertures which are above the moving conveyor to ultrasonically cut vertically oriented dough ropes extruded from the plurality of die apertures to obtain dough pieces which fall onto the moving conveyor in a substantially uniform array of rows, each of the ultrasonic cutting blades having its own ultrasonic power supply, and the power supply to each ultrasonic cutting blade is varied to lower the power supply input and increase friction during cutting as the blade travels across the dough rope using an amplitude of 10 to 19 microns.

19. Apparatus for the continuous production of cookies as claimed in claim 18 wherein the plurality of ultrasonic cutters are journaled or connected together or mounted or attached to a single reciprocating mechanism to synchronize their movement for cutting a plurality of at least substantially vertically oriented extrudate dough ropes so that all of the blades contact and cut one or a plurality of different extrudate ropes at least substantially simultaneously so that the cut dough pieces fall in an at least substantially uniform straight row across the oven band, and each of the ultrasonic cutting blades is mounted to a booster and the booster varies the amplitude of said ultrasonic cutting as the blade cuts across the dough rope to provide a roughened top surface on the dough piece.
