Abstract: A device for heating and foaming milk includes a steam-generating device to generate steam by heating water. The steam generating device has a steam outlet. A shut-off value is coupled to the steam outlet. A first line is coupled via the shut-off valve to the steam outlet of the steam-generating device so that steam can be discharged through the first line from the steam-generating device. The first line is selectively opened and closed with the aid of the shutoff valve. The first line has an outlet arranged to be submerged directly into a container which contains the milk to be foamed. A second line having an outlet is coupled to a pump to pump air into the second line. The outlet of the second line is arranged to be submerged separately and at a distance to the first line directly into the container holding the milk to be foamed, so that steam and air is supplied completely separate from each other during the heating and foaming of the milk.
