ABSTRACT:
A device is disclosed for the preparation of milk froth for cappuccino (milk-coffee beverage) to be employed as an accessory to coffee or espresso makers or steam preparation machines equipped with a superheated steam generator and a steam pipe. A venturi is disposed at the outlet end of the steam pipe and has an associated air intake conduit and a milk intake conduit that are arranged in such a way that the outlet opening of the air intake conduit and the outlet opening of the milk intake conduit open in the venturi in the zone of greatest subatmospheric pressure. Due to the subatmospheric pressure created in the venturi by the flowing steam, air and milk are sucked in and mixed with the superheated steam in the diffusion path of the venturi. Thus the three-component mixture of steam, air and milk required for the generation of milk froth is created already in the venturi and the desired milk froth is available at the outlet of the venturi.
The device according to the invention is distinguished in that, compared to prior art foaming aids, optimum frothing results are realized even in connection with low power steam generators.
