MILK-FEEDING DEVICE FOR A FULLY AUTOMATIC COFFEE MACHINE, AND CORRESPONDING METHOD

摘要

For a milk-feeding device (1) which feeds milk (7) with the aid of a stream (9) of steam dispensed from a steam nozzle (2), on the basis of the Venturi effect, it is proposed that, by appropriate orientation of an admixing opening (4) and possibly with the aid of deflecting surfaces (46), a stream (8) of milk taken in by the stream (9) of steam should be allowed to flow tangentially onto the stream (9) of steam, so that, even when the flow rates of the stream (8) of milk are very low, it is still possible to ensure that the stream (8) of milk is fed as far as possible in a problem-free manner. For this purpose, the stream (8) of milk is oriented in the direction (51) of the stream (9) of steam even before the stream (8) of milk comes into contact with the stream (9) of steam (cf. figure 11).
