Abstract: A frothing head for heating and whipping milk is provided. The frothing head has a mixing chamber, a restriction duct extending from the mixing chamber, a frothing chamber arranged at one end of the restriction duct, a distribution duct, an air suction duct leading into the mixing chamber, and a milk suction duct leading into the mixing chamber. The frothing chamber is disc-shaped, and the restriction duct leads tangentially into the frothing chamber. The distribution duct extends axially from a center of a bottom surface of the frothing chamber and has an upper portion and a lower portion having a greater diameter than the upper portion.

Abstract: A device for heating and frothing milk which has a steam generator and a jet pump is provided. The jet pump has a steam inlet through which pressurized steam is injectable into the jet pump, a first suction inlet and a second suction inlet. The first suction inlet is configured to connect to a milk reservoir. An air inlet is connectable or connected to the second suction inlet of the jet pump for drawing air into the jet pump. A bypass valve is connected to the second suction inlet of the jet pump and has a bypass inlet. The bypass valve is switchable between a first position in which the second suction inlet of the jet pump is shut off from the steam generator, and a second position in which the second suction inlet is in fluid communication with the bypass inlet of the bypass valve for suction of steam.

Abstract: The device (1) comprises a steam generator (2, 4), a compressed-air generator (9, 11) and a dispensing wand (10) connected or adapted to be connected to the steam generator (2, 4) and the compressed-air generator (9, 11) and adapted to be introduced into a receptacle (R) containing the milk (M) to be heated and frothed. The dispensing wand (10) defines first and second conduits (21, 22) separate from each other and having respective separate inlets (10a, 10b) for connection to the steam generator (2, 4) and the compressed-air generator (9, 11), respectively, as well as respective separate outlets (10c, 23; 10d, 24) for dispensing during use a flow of steam and a flow of compressed air, respectively, within the milk (M) contained in the receptacle (R), said outlets (23, 24) being arranged such that the flows of steam and compressed air exiting therefrom intersect each other.
