Abstract

Various beverage preparation systems and methods are disclosed. The beverage preparation system can include a dispensing unit configured to receive beverage, such as a shot of espresso, from a beverage preparation machine. The dispensing unit can include a dispensing unit with a first end and a second end. The dispensing unit can be rotatable between an upright position and an inverted position. The dispensing unit can be configured to receive the beverage through the second end when the dispensing unit is in the upright position, and can be configured to receive cleansing fluid through the second end when the dispensing unit is in the inverted position. In some embodiments, when the dispensing unit is in an intermediate position between the upright and inverted positions, the dispensing unit is configured to dispense the beverage out of the first end and into a cup or other vessel.

First claim

The following is claimed:

1. A method of producing a heated and aerated liquid, the method comprising: receiving a container on a base; opening a fluid passage, the fluid passage extending through the base and through a lower portion of the container, the fluid passage being offset from a radial center of the container: introducing a liquid through the fluid passage; collecting the liquid in the container; introducing a gas through the fluid passage; passing the gas generally vertically upward through the liquid collected in the container; heating the liquid in the container with the gas, wherein aerating the liquid with the gas comprises turbulating the liquid with the gas introduced through the fluid passage; aerating the liquid with the gas; and closing the fluid passage.

2. The method of claim 1 , wherein the liquid comprises milk.

3. The method of claim 1 , wherein the gas comprises steam and air.

4. The method of claim 1 , wherein opening the fluid passage comprises: opening a port in the base and opening a port in the container.

5. The method of claim 1 , wherein opening the fluid passage occurs automatically and substantially concurrently with receiving the container on the base.

6. The method of claim 1 , wherein closing the fluid passage occurs automatically in response to the container being removed from the base.

7. The method of claim 1 , wherein introducing the liquid through the fluid passage comprises passing the liquid through a bottom of the container.

8. The method of claim 1 , wherein opening the fluid passage comprises opening a valve in at least one of the base and the lower portion of the container.

9. The method of claim 1 , wherein introducing the liquid through the fluid passage comprises introducing the liquid upwardly through the fluid passage.

10. The method of claim 1 , wherein: opening the fluid passage comprises opening a first port and opening a second port; introducing the liquid through the fluid passage comprises introducing the liquid through the first port; and introducing the gas through the fluid passage comprises introducing the gas through the second port.

11. A method of producing a heated and aerated liquid, the method comprising: receiving a container on a base; magnetically coupling the container with the base; opening a fluid passage, the fluid passage extending through the base and through a bottom of the container, the fluid passage being offset from a radial center of the container: introducing a gas through the fluid passage and into the container; passing the gas through a liquid in the container; heating the liquid in the container with the gas; aerating the liquid with the gas, wherein aerating the liquid with the gas comprises forming a turbulent flow in the liquid with the gas introduced through the fluid passage; and closing the fluid passage.

12. The method of claim 11 , further comprising introducing the liquid into the container through the bottom of the container, and collecting the liquid in the container.

13. The method of claim 12 , where introducing the liquid into the container through the bottom of the container comprises: introducing the liquid through the fluid passage.

14. The method of claim 12 , where introducing the liquid into the container through the bottom of the container comprises: introducing the liquid through a second fluid passage.

15. The method of claim 11 , further comprising orienting the container relative to the base.

16. The method of claim 11 , further comprising mixing pressurized steam and air to form the gas.

17. The method of claim 11 , wherein opening the fluid passage comprises: opening a check valve in the bottom of the container.

18. The method of claim 11 , wherein closing the fluid passage comprises automatically closing the fluid passage in response to the container being removed from the base.

19. The method of claim 11 , wherein the gas comprises steam and air.

20. The method of claim 11 , wherein opening the fluid passage comprises: opening a port in the base and opening a port in the container.

21. The method of claim 11 , wherein opening the fluid passage occurs automatically and substantially concurrently with receiving the container on the base.

22. The method of claim 11 , wherein closing the fluid passage occurs automatically in response to the container being removed from the base.
