Abstract

A method for producing an ice cream product with an ice cream machine having an extrusion nozzle and a cutting tool is provided. The method comprises providing an ice cream mixture, extruding the ice cream mixture through the extrusion nozzle, and cutting the ice cream mixture with the cutting tool into an ice cream product, wherein the cutting tool is an ultrasound cutting tool. An ice cream machine for producing an ice cream product is also provided.

First claim

The invention claimed is:

1. A method for producing, from an ice cream mixture, an ice cream product with an ice cream machine having an extrusion nozzle and a cutting tool, the method comprising:
extruding the ice cream mixture through the extrusion nozzle in a direction of a flow; and
cutting the ice cream mixture with the cutting tool into the ice cream product while the cutting tool moves at least partly in the direction of the flow and while the cutting tool moves transversally with respect to the direction of the flow, wherein the cutting tool is an ultrasound cutting tool.

2. The method according to claim 1 , wherein the ice cream mixture comprises inclusions.

3. The method according to claim 1 , wherein the extrusion nozzle comprises a flap arranged at an orifice of the extrusion nozzle, and wherein the step of cutting the ice cream mixture with the cutting tool comprises cutting the ice cream mixture against the flap.

4. The method according to claim 1 , wherein the cutting tool is angled between 0° and 12° relative to the direction of the flow and wherein the step of cutting the ice cream mixture comprises cutting the ice cream mixture with the angled cutting tool.

5. The method according to claim 1 , wherein the cutting tool comprises at least two ultrasound cutting knives and wherein the step of cutting the ice cream mixture with the cutting tool comprises cutting the ice mixture with the at least two ultrasound cutting knives from opposite sides of the ice cream mixture.

6. The method according to claim 1 , wherein the extrusion nozzle is arranged horizontally and the extruding is performed horizontally or wherein the extrusion nozzle is arranged vertically and the extruding is performed vertically.

7. The method according to claim 1 , wherein the step of cutting comprises cutting the ice cream mixture in a horizontal or vertical direction.

8. The method according to claim 1 , further comprising arranging the extruded ice cream mixture or ice cream product on a conveyer tray.

9. The method according to claim 1 , further comprising inserting a stick into the ice cream mixture through a notch in the extrusion nozzle.

10. The method according to claim 1 , wherein the cutting tool moves transversally at a speed higher than a speed at which the ice cream mixture flows in the direction of the flow.

11. An ice cream machine for forming ice cream products based on an ice cream mixture, the machine comprising:
an extrusion nozzle for extruding the ice cream mixture in a direction of a flow, wherein the ice cream mixture has inclusions; and
a cutting tool for cutting the ice cream mixture from the extrusion nozzle into the ice cream products while the cutting tool moves at least partly in the direction of the flow and while the cutting tool moves transversally with respect to the direction of the flow;
wherein the cutting tool is an ultrasound cutting tool.

12. The ice cream machine according to claim 11 , further comprising a flap arranged at an orifice of the extrusion nozzle, wherein the cutting tool is arranged to cut the ice cream mixture against the flap.

13. The ice cream machine according to claim 11 , wherein the extrusion nozzle is a horizontally arranged extrusion nozzle adapted to extrude the ice cream mixture horizontally or wherein the extrusion nozzle is a vertically arranged extrusion nozzle adapted to extrude the ice cream mixture vertically.

14. The ice cream machine according to claim 13 , wherein:
the extrusion nozzle is a horizontally-arranged extrusion nozzle adapted to extrude the ice cream mixture horizontally; and
the cutting tool is arranged to cut through the ice cream mixture in a vertical direction.

15. The ice cream machine according to claim 13 , wherein:
the extrusion nozzle is a vertically-arranged extrusion nozzle adapted to extrude the ice cream mixture vertically; and
the cutting tool is arranged to cut through the ice cream mixture in a horizontal direction.

16. The ice cream machine according to claim 11 , wherein the cutting tool is arranged with an angle of between 0° and 12° relative to the direction of the flow.

17. The ice cream machine according to claim 11 , wherein the cutting tool comprises at least two ultrasound cutting knives arranged to cut the ice cream mixture from opposite side of the ice cream mixture.

18. The ice cream machine according to claim 11 , wherein the ultrasound cutting tool is configured to operate at a frequency between 5 kHz and 25 kHz.

19. The ice cream machine according to claim 11 , further comprising a conveyor tray adapted to transport the ice cream products.

20. The ice cream machine according to claim 11 , wherein:
the extrusion nozzle further comprises a notch arranged to insert a stick into the ice cream mixture.
