Device and method for producing milk-air emulsions

3:

• The device according to claim 2, wherein the at least one air throttle is connected to the control device (9) and is designed as a controllable motorized air throttle (13).

4:

• The device according to claim 2, wherein the at least one controllable air pump is designed such that a delivery rate is variable.

6-7. (canceled)

8:

• The device according to claim 2, wherein the plurality of air throttles are designed as static air throttles (28, 29, 31, 32), to which one or more air selection valves (27, 30) connected to the control device (9) and controllable thereby are assigned.

9:

• The device according to claim 1, wherein the steam system has at least one steam boiler (15), at least one controllable steam valve (19), and a steam line (20).

(canceled)

11:

• The device according to claim 1,
• wherein the air line (14) and the steam line (20) open into a common combined steam/air line (4) which is guided through the steam lance (4), or the air line (14) and the steam line (20) are guided separately though the steam lance, and
• wherein the steam lance is configured to be immersed in the milk in the vessel.

(canceled)

13:

• A beverage dispenser, in particular coffee machine, having at least one device according to claim 1.

16-17. (canceled)

18:

• The method according to claim 14, wherein the vessel (2) is filled with milk manually or automatically.

19:

• The method according to claim 14, wherein during operation of the method, at least one or more operating parameters are determined once or several times, which are used to adjust the milk-air emulsion production profile during the operation of the method.

20:

• The method according to claim 14, wherein the operating parameter or parameters determined once or several times during operation of the method, which are used to adjust the milk-air emulsion production profile, comprise a temperature of the milk in the vessel (2).

(canceled)

22:

• The method according to claim 14, wherein during the production of the milk-air emulsion, an amount of air or steam introduced into the milk is kept constant or varied over time and/or temperature.

23:

• The method according to claim 14, wherein, after starting the milk-air emulsion production program, a preselection of milk quantity and/or milk type and/or consistency of the milk-air emulsion to be produced is made via data input, wherein after starting the milk-air emulsion production program, the air-emulsion program suggests presettings for air addition duration and/or air addition quantity and/or target temperature.

24-25. (canceled)

26:

• The method according to claim 14, wherein foam quantity is adjusted by adjusting a duration of air addition.

(canceled)

28:

• The method according to claim 24, wherein the target temperature is adjusted by defining a switch-off temperature for steam addition.

29:

• The method according to claim 14, wherein during the production of the milk-air emulsion, a milk temperature in the vessel (2) is measured and the measured temperature is included in the control.

30:

• The method according to claim 14, wherein during the production of the milk-air emulsion, a further milk-air emulsion production profile is determined and stored as a function of the type of milk and/or the desired foam consistency and is used to control a sequence of the milk-air emulsion production.

31:

• The method according to claim 14, wherein during the production of the milk-air emulsion, the control of the air system (8) comprises three or more phases, wherein in a first phase, no air is added up to a temperature value “1”, then, in a second phase, a small amount of air is added up to a temperature value “2,” then, in a third phase, a large amount of air is added up to a temperature value “3,” and then, in a fourth phase, a very small amount of air is added from a temperature value “4” onwards.
