Abstract: An emulsifying device (10) for liquids, in particular milk, comprises a container (11) containing the liquid to be emulsified and to which is connected near the bottom a first horizontal duct (14) connected to a steam source. The first duct (14) has a constriction (15) downstream from which is connected a second duct (17) with an opening at the top flowing into said container (11) in a position near the level of its edge so as to draw in air and emulsified liquid reaching the upper opening level as the steam passes into the first duct (14). Container (11) comprises a drain (12) with a closing plug (13) removable to take away the emulsified liquid.

Abstract: A hot-beverage-brewing machine is disclosed in which the improvements consist in having the heating means directly applied to a cuplike compartment in which a single dosage unit is individually brewed and in providing a rotary blender dipping in the cuplike compartment to improve the heat exchange between the compartment wall and the liquid. Timing means are provided for having the water and soluble powder feeds in the appropriate sequence consistently with the other operations which are required for brewing the beverages.
