Title: DEVICE FOR HEATING MILK OR MILK FOAM
Abstract:
The invention relates to a device for heating milk or milk foam using steam in a steam/liquid mixer (5) which is provided with a tubular mixing chamber (21), with at least one steam-feed line (16) and with a milk-/milk-foam-feed nozzle (25) oriented in the longitudinal direction of the mixing chamber, wherein the steam-feed line (16) opens out into a steam-feed chamber (20), which is arranged upstream of the mixing chamber (21) and is connected to the mixing chamber (21) by steam-inlet bores (22) running around the milk-/milk-foam-feed nozzle (25) in the longitudinal direction of the mixing chamber. Said steam-inlet bores (22) are oriented in a preferably axis-parallel manner in relation to the centre axis of the mixing chamber (21). This arrangement of the steam-inlet bores (22) gives rise to uniformly thorough mixing of the steam with the cold milk or the milk foam in the mixing chamber and therefore to optimum heating of the milk or of the milk foam.
