Jug for the preparation of beverages and beverage producing system

1. A jug for preparation of a hot beverage comprising:

a body and a cover, the cover being provided with a steam inlet and supporting a stirrer, and the stirrer being detachably connected to the cover and configured to rotate under an effect of a steam jet exiting a steam nozzle near a bottom of the body for impinging on the stirrer to cause rotation of the stirrer, the bottom of the body being farther from the cover than a top of the body,

wherein the stirrer extends from the cover towards the bottom of the body of the jug,

wherein the steam nozzle is detachably connected to the cover and extends towards the bottom of the body of the jug and is positioned adjacent to the stirrer, and

wherein a steam flow path is provided between the steam inlet and the steam nozzle.

2. The jug according to claim 1 , wherein the stirrer comprises a shaft rotatably supported at a proximal end on the cover and provided with an agitator arranged adjacent a distal end of the shaft near the bottom of the body opposite the proximal end, and wherein the steam nozzle has an outlet aperture at an end of the steam nozzle, near the agitator, for the exiting of the steam jet.

3. The jug according to claim 2 , wherein the shaft and the steam nozzle extend parallel to one another.

4. The jug according to claim 2 , wherein the agitator comprises a plurality of blades.

5. The jug according to claim 2 , wherein the outlet aperture is orientable towards the agitator, and wherein the steam nozzle is configured to output steam for acting on the agitator to drive the agitator into rotation.

6. The jug according to claim 2 , wherein the steam nozzle is fluidly connected through a tube with the steam inlet.

7. The jug according to claim 2 , comprising a turbine configured to rotate along with the shaft, said turbine being arranged in the steam flow path between the steam inlet and the steam nozzle, wherein steam from the steam inlet drives the turbine and the shaft into rotation before flowing through the steam nozzle.

8. The jug according to claim 7 , wherein the turbine is detachably connectable to and disconnectable from the shaft.

9. The jug according to claim 7 , wherein the turbine is connected at the proximal end of the shaft.

10. The jug according to claim 7 , wherein the turbine is rotatably supported in a housing provided in the cover of the jug, said housing being in fluid communication with the steam inlet and with the steam nozzle, and wherein steam entering the steam inlet flows in the steam nozzle through the housing, driving the turbine and the stirrer into rotation.

11. The jug according to claim 10 , wherein the turbine includes a driving spindle, the driving spindle being rotatably supported on the cover and projecting from the housing towards the bottom of the body, and the driving spindle being torsionally connectable to and disconnectable from the stirrer.

12. The jug according to claim 1 , wherein the steam nozzle and the stirrer are connectable to and detachable from the cover one independently of the other, wherein the jug is configured to operate with one of the stirrer and the steam nozzle connected to the cover.

13. A system comprising: a beverage preparing machine with a steam generator and a steam dispensing nozzle; and a jug for preparation of a hot beverage, the jug comprising:

a body and a cover, the cover being provided with a steam inlet and supporting a stirrer, and the stirrer being detachably connected to the cover and configured to rotate under an effect of a steam jet exiting a steam nozzle near a bottom of the body for impinging on the stirrer to cause rotation of the stirrer, the bottom of the body being farther from the cover than a top of the body,

wherein the stirrer extends from the cover towards the bottom of the body of the jug,

wherein the steam nozzle is detachably connected to the cover and extends towards the bottom of the body of the jug and is positioned adjacent to the stirrer,

wherein a steam flow path is provided between the steam inlet and the steam nozzle, and

wherein the steam dispensing nozzle is configured to connect with the steam inlet of the jug.

14. The system according to claim 13 , wherein the steam nozzle and the stirrer are connectable to and detachable from the cover one independently of the other, wherein the jug is configured to operate with one of the stirrer and the steam nozzle connected to the cover.

15. The system according to claim 13 , wherein the shaft and the steam nozzle extend parallel to one another.
