"AUTOMATIC DEVICE FOR OBTAINING FROTHY MILK" An automatic device for obtaining frothy milk comprising a first mixing assembly (30) which feeds a second frothing assembly (30), consisting of an expansion chamber (17), a milk feeding duct (31) being provided in the first assembly (30) inside a nozzle (13) for the pressurized steam, this nozzle being coaxial to the milk duct (31), the outlet of this duct slightly projecting over the steam outlet; the milk-steam mixture which is formed, tangentially flows to the expansion chamber, which has a circular section. Preferably the diameter of the nozzle (12) of the outflowing milk is about 1,1-1,2 mm, while the clear radial span of the annular section nozzle (13) of the outflowing steam is about 0,2 mm, the milk outlet projecting about 0,2 mm with respect to the steam outlet. |
