Abstract

A machine for preparing a cooled food product includes a receiving seat, for accommodating an essentially cup-shaped container, including a heat exchange element having a heat exchange contact surface arranged to be in contact with an outer surface of a side wall of the container when the container is placed in the machine, and a stirring unit connectable to a stirring member and arranged for driving the stirring member according to a combination of movements, wherein at least one of the combination of movements has a component directed towards the interior of the container when placed in the receiving seat. Also disclosed is a system including the machine, a container, and a method of preparation.

First claim

The invention claimed is:

1. A machine for preparing a cooled food product, the machine comprising:
a receiving seat configured to accommodate a container, the receiving seat comprising a heat exchange element having a heat exchange contact surface arranged to be in contact with an outer surface of a side wall of the container when the container is placed in the machine;
a cooling unit arranged for cooling the heat exchange element;
a stirring unit connectable to a stirring member and arranged for driving the stirring member according to a combination of movements, the combination of movements comprising a first rotational movement of the stirring member about a longitudinal axis of the stirring member arranged offset to a central longitudinal axis of the receiving seat and/or of the container and a closed loop movement of the stirring member about the central longitudinal axis of the container or the receiving seat,
wherein a direction and an amount of velocities of the first rotational movement and of the closed loop movement of the stirring member are set depending on the cooled food product to produce; and
a connection member connecting the stirring member to the stirring unit, the connection member comprising a first driving member that rotates the stirring member about the longitudinal axis of the stirring member, the connection member further comprising a second driving member that engages a support shaft of the stirring member to drive the support shaft in orbital rotation about a central axis of the support shaft.

2. The machine according to claim 1 , wherein the closed loop movement of the stirring member is an orbital rotational movement about the central longitudinal axis of the container or the receiving seat.

3. The machine according to claim 1 , wherein an angular velocity of the closed loop movement of the stirring member about the central longitudinal axis of the container differs from an angular velocity of the stirring member about the longitudinal axis of the stirring member.

4. The machine according to claim 1 , wherein an angular velocity of the closed loop movement of the stirring member about the central longitudinal axis of the container is less than an angular velocity of the stirring member about the longitudinal axis of the stirring member.

5. The machine according to claim 4 , wherein the angular velocity of the closed loop movement of the stirring member is less than 35% of the angular velocity of the stirring member.

6. The machine according to claim 1 , wherein the combination of movements further comprises a linear movement of the stirring member.

7. The machine according to claim 1 , wherein the combination of movements further comprises a radial reciprocating translational movement of the stirring member relative to the container or the receiving seat.

8. The machine according to claim 1 , comprising a control unit configured to control at least a direction and an amount of velocities of the stirring member, as a function of a type of the cooled food product to be prepared.

9. The machine according to claim 8 , wherein the velocities of the stirring member are either individually provided within a given sequence or as the combined movement of the stirring member within the container or the receiving seat.

10. The machine according to claim 8 , wherein the control unit individually controls a direction and velocities of the first driving member and the second driving member.

11. The machine according to claim 1 , wherein the stirring member is designed for being removably connectable to the stirring unit of the machine.

12. A system comprising:
a machine for preparing a cooled food product, the machine comprising: a receiving seat configured to accommodate a container, the receiving seat comprising a heat exchange element having a heat exchange contact surface arranged to be in contact with an outer surface of a side wall of the container when the container is placed in the machine; a cooling unit arranged for cooling the heat exchange element; and a stirring unit connectable to a stirring member and arranged for driving the stirring member according to a combination of movements, the combination of movements comprising a first rotational movement of the stirring member about a longitudinal axis of the stirring member arranged offset to a central longitudinal axis of the receiving seat and/or of the container and a closed loop movement of the stirring member about a central longitudinal axis of the container or the receiving seat, wherein a direction and an amount of velocities of the first rotational movement and of the closed loop movement of the stirring member are set depending on the cooled food product to produce; and a connection member connecting the stirring member to the stirring unit, the connection member comprising a first driving member that rotates the stirring member about the longitudinal axis of the stirring member, the connection member further comprising a second driving member that engages a support shaft of the stirring member to drive the support shaft in orbital rotation about a central axis of the support shaft; and
the container comprising a heat transfer portion having an inner freezing surface, arranged such that the heat transfer portion overlaps with the heat exchange contact surface of the machine when the container is arranged in the receiving seat of the machine.

13. The system according to claim 12 , wherein the stirring member when connected to the machine is arranged adjacent to the inner freezing surface of the container to define an essentially vertically extending scraping area between the inner freezing surface and an outer annular scraping surface of the stirring member.

14. The system according to claim 13 , wherein a vertical extension of the essentially vertically extending scraping area within the container is equal to or larger than a vertical extension of the heat exchange contact surface of the machine.

15. A method for preparing a cooled food product in a machine comprising a receiving seat configured to accommodate a container, the receiving seat comprising a heat exchange element having a heat exchange contact surface arranged to be in contact with an outer surface of a side wall of the container when the container is placed in the machine; a cooling unit arranged for cooling the heat exchange element; and a stirring unit connectable to a stirring member and arranged for driving the stirring member according to a combination of movements, the combination of movements comprising a first rotational movement of the stirring member about a longitudinal axis of the stirring member arranged offset to a central longitudinal axis of the receiving seat and/or of the container and a closed loop movement of the stirring member about a central longitudinal axis of the container or the receiving seat, wherein a direction and an amount of velocities of the first rotational movement and of the closed loop movement of the stirring member are set depending on the cooled food product to produce; and a connection member connecting the stirring member to the stirring unit, the connection member comprising a first driving member that rotates the stirring member about the longitudinal axis of the stirring member, the connection member further comprising a second driving member that engages a support shaft of the stirring member to drive the support shaft in orbital rotation about a central axis of the support shaft, the method comprising:
placing the container containing a predefined amount of ingredients into the receiving seat of the machine;
cooling the container b
