A device (10) for heating and emulsifying liquids, in particular drinks, which is unusually capable of generating a dense and creamy foam, comprises a steam-emitting member (12) with which a hollow body (14) can be associated. The steam-emitting member (12) comprises a spout (50) positioned along the hollow body (14) at a height such as to be above the level of the liquid to be emulsified. Inserted coaxially inside the hollow body (14) is a duct (88) which defines a first passage (98) and a second passage (100). A region for communication between the first passage (98), the second passage (100) and a third passage (102) for air, which is placed in communication with a groove (84) formed in the inner surface of the hollow body (14), is provided between the steam-emitting member (12) and the duct (88). The steam-emitting member (12) comprises two annular projections (54, 56) provided with sectors which have different transverse dimensions and which are offset relative to one another and define a labyrinthine path.
