An assembly for generating milk foam and for heating milk comprises a milk
supply container, a steam generator and a mixing element. The mixing
element includes a first steam inlet channel, a necking located downstream
of the first steam inlet channel, an air inlet channel opening into the
necking and a milk inlet channel. The milk is fed to the milk inlet
channel of the mixing element by means of a pump. Moreover, the mixing
element is provided with a main channel whose inlet communicates with the
necking, whereby the milk inlet channel opens into the main channel
downstream of its inlet. Between the necking and the opening of the milk
inlet channel, a second steam inlet channel opens into the main channel.
