Abstract

The present disclosure relates to an ice cream machine having a filling zone and an emptying zone. The ice cream machine may include a rotatable unit, a mould for receiving ice cream, a stick providing arrangement, and a guiding structure arranged to prevent more than one stick from entering the groove of the mould from the stick providing arrangement. The stick providing arrangement is arranged such that a rotation of the rotatable unit causes the groove to match the position of the stick providing arrangement and thereby allow a single stick to enter the groove, wherein further rotation of the rotatable unit causes one of the sidewalls of the groove to bring the stick along the rotational movement of the rotatable unit.

First claim

The invention claimed is:

1. An ice cream machine having a filling zone and an emptying zone, the ice cream machine comprising:
a rotatable unit having a radial extension and a rotational axis;
a mould for receiving ice cream, the mould configured to rotate with the rotatable unit, the mould comprising a groove for receiving a stick, the groove comprising two sidewalls and a bottom;
a stick providing arrangement configured to supply a stick to the groove of the mould, the stick providing arrangement configured to supply the stick in a direction perpendicular to the rotational axis of the rotatable unit, wherein a longitudinal direction of the stick is arranged parallel to the rotational axis of the rotatable unit;
a guiding structure configured to prevent more than one stick at a time from entering the groove of the mould from the stick providing arrangement;
wherein the stick providing arrangement is arranged such that upon rotation of the rotatable unit, the groove matches a position of the stick providing arrangement to enable a single stick to enter the groove;
wherein the rotatable unit is configured such that further rotation of the rotatable unit causes one of the sidewalls of the groove to bring the stick along with a rotational movement of the rotatable unit; and
wherein the guiding structure comprises a slit which is sloping radially inwards in a rotational direction of the rotatable unit such that the stick reaches the bottom of the groove.

2. The ice cream machine according to claim 1 , wherein the stick providing arrangement is arranged to provide the stick in a final longitudinal direction, along the rotational axis, for the ice cream product to be produced.

3. The ice cream machine according to claim 1 , wherein the stick providing arrangement and the guiding structure are arranged upstream of the filling zone of the ice cream machine.

4. The ice cream machine according to claim 1 , wherein the stick providing arrangement is configured to hold a plurality of sticks stacked with a flat surface of the sticks facing each other and to supply a stick with the flat surface facing the rotational axis of the rotatable unit.

5. The ice cream machine according to claim 1 , further comprising:
an extrusion nozzle for extruding ice cream into the mould, wherein the extrusion nozzle is arranged at the filling zone; and
an ejection mechanism for ejecting ice cream radially out of the mould at the emptying zone.

6. The ice cream machine according to claim 1 , comprising at least five moulds.

7. The ice cream machine according to claim 2 , wherein the stick providing arrangement and the guiding structure are arranged upstream of the filling zone of the ice cream machine.

8. A method for producing ice cream with a machine having an extrusion nozzle, an ejection mechanism, a rotatable unit, at least one mould configured to rotate with the rotatable unit, the mould comprising a groove for receiving a stick, the groove comprising two sidewalls and a bottom, a stick providing arrangement for supplying the stick having a longitudinal direction to the groove of the mould, the stick providing arrangement configured to supply the stick in a direction perpendicular to a rotational axis of the rotatable unit with the longitudinal direction of the stick parallel to the rotational axis of the rotatable unit, and a guiding structure configured to prevent more than one stick from entering the groove of the mould from the stick providing arrangement, the guiding structure comprising a slit which slopes radially inwards in a rotational direction of the rotatable unit such that the stick reaches the bottom of the groove, the method comprising the steps of:
providing ice cream with or without inclusions;
providing ice cream sticks in the stick providing arrangement;
rotating the rotatable unit, whereby the groove matches the position of the stick providing arrangement such that a single stick enters the groove;
rotating the rotatable unit such that one of the sidewalls of the groove brings the stick along a rotational movement towards the filling zone;
extruding the ice cream through the extrusion nozzle into the mould to form an ice cream lolly; and
ejecting the ice cream lolly out of the mould using the ejection mechanism.
