ABSTRACT:
A device for frothing and steaming milk has a steamer (1) and a steamer tube (3) connected to a steam conduit (2). The steam conduit (2) is provided with an air feeder port (6) which can be closed off. The steamer tube (3) has a temperature sensor (11) for sensing the milk temperature. The device has furthermore a controller (13) devised to open/close the air feeder port (6) as a function of the operating mode and/or sensed milk temperature. When the milk is steamed the air feeder port (6) remains closed whilst when frothing the milk it normally firstly remains closed until opened at a predefined milk temperature so that air can be mixed in the flow of steam.
