Abstract

The invention relates to an ice cream machine having a filling zone and an emptying zone. The ice cream machine comprises a rotatable unit having a radial extension, a mould for receiving ice cream, the mould being arranged to rotate with the rotatable unit, an extrusion nozzle for extruding ice cream into the mould, the extrusion nozzle being arranged at the filling zone. The ice cream machine further comprises an ejection mechanism for ejecting ice cream radially out of the mould at the emptying zone. The invention also relates to a method for producing an ice cream product using an ice cream machine.

First claim

1 . An ice cream machine having a filling zone and an emptying zone, said ice cream machine comprising:
a rotatable unit having a radial extension; a mould for receiving ice cream, said mould being arranged to rotate with said rotatable unit; an extrusion nozzle for extruding ice cream into said mould, said extrusion nozzle being arranged at said filling zone; an ejection mechanism for ejecting ice cream radially out of said mould at said emptying zone.

2 . An ice cream machine according to claim 1 , wherein said ejection mechanism comprises a piston connected to said mould.

3 . An ice cream machine according to claim 2 , wherein a bottom of said mould is radially movable together with said piston.

4 . An ice cream machine according to claim 1 , comprising a transporting zone between said filling zone and said emptying zone, wherein at said transporting zone said ejection mechanism is arranged to move said mould radially inwards of said rotatable unit.

5 . An ice cream machine according to claim 2 , wherein said piston is a reciprocal piston.

6 . An ice cream machine according to claim 5 , wherein said piston is reciprocal by being connected to a cam shaft arranged at a hub of the rotatable unit.

7 . An ice cream machine according to claim 5 , wherein said piston is reciprocal by being pneumatic, hydraulic or electrically actuable.

8 . An ice cream machine according to claim 1 , comprising at least two moulds, wherein the extrusion nozzle is arranged to cover more than one mould at said filling zone.

9 . An ice cream machine according to claim 1 , comprising a sealing arranged to seal said extrusion nozzle to said rotatable unit.

10 . An ice cream machine according to claim 1 , comprising a detaching mechanism arranged to detach said ice cream from said mould at said emptying zone, wherein said detaching mechanism is at least one of the following: a scrape, a wire, a pneumatic-driven system, an ultrasound cutting tool.

11 . An ice cream machine according to claim 1 , comprising a conveyer tray arranged to receive said ice cream from said mould at said emptying zone, wherein the rotational speed of the rotatable unit is adapted to the speed of the conveyer belt.

12 . An ice cream machine according to claim 1 , comprising a stick providing arrangement arranged to provide a stick for each mould.

13 . A method for producing an ice cream product using an ice cream machine having an extrusion nozzle, a rotatable unit, at least one mould arranged to rotate with said rotatable unit, and an ejection mechanism, said method comprising the steps of:
providing ice cream with or without inclusions; extruding said ice cream through the extrusion nozzle into the mould; ejecting said ice cream out of said mould using said ejection mechanism.

14 . The method according to claim 13 , wherein the step of ejecting said ice cream comprises using a piston to push said ice cream out of said mould in a radial direction of said rotatable unit.

15 . The method according to any one of claim 13 , wherein the ice cream machine comprises at least two moulds, and wherein the step of extruding said ice cream comprises extruding ice cream into more than one mould.
