A mixing, heating and/or frothing and/or whipping device for preparing hot milk-based beverages, comprising a central body which is detachably associable with a steam delivery tube and an outer casing which fits over the central body; the central body protrudes partially from the outer casing in order to immerse it partially in a beverage together with part of the outer casing and forms channels for the passage of air and of liquid to be frothed, in order to mix them with the steam and consequently mix the three flows, the device further comprising at least one first mixing region for forming a mixture composed of the air and the liquid to be whipped, which arrive respectively from at least one intake channel and at least one rising channel, which are formed by the central body and by the outer casing, the formed mixture then converges in at least one second mixing region with the steam that is injected in the second mixing region and arrives from the delivery tube and then enters the beverage by means of at least one discharge channel that extends from the second mixing region.

A frothing, heating and/or whipping device for preparing hot beverages, comprising a central body detachably associable with a steam delivery tube and an outer casing which fits over said central body, between said central body and said casing there being at least one channel for the passage of the liquid to be frothed, an air intake channel and an outflow channel for the frothed liquid, wherein the device comprises at least two spatially separated mixing regions, a first one of said mixing regions being provided in a meeting point between said at least one channel for the passage of the liquid to be frothed and the air intake channel, in order to form a first mixture composed of the air and the liquid to be frothed, a second one of said mixing regions being provided in a meeting point between said at least one liquid passage channel and said outflow channel for the frothed liquid, said second mixing region being arranged so as to mix said first mixture with the steam that arrives from said delivery tube, said device comprising a plurality of longitudinal grooves which are adapted to form said at least one channel for the passage of the liquid to be frothed, said air intake channel and said outflow channel for the frothed liquid.
