A frothing device including 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 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 includes a first mixing region for forming a mixture composed of the air and the liquid to be frothed, which arrive respectively from an air intake channel and a liquid rising channel, which are formed by the central body and by the outer casing, the formed mixture then converges in a 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 a discharge channel that extends from the second mixing region.

1. 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, said central body having a longitudinal central axis and 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, the device comprising 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 extend longitudinally on said central body and which form, together with an inner surface of said outer casing fit over said central body and laterally to said longitudinal central axis of said central body, each of: 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. 2. The device according to claim 1, wherein said central body is a substantially longitudinally elongated contoured insert, which has a substantially tubular end portion which can be connected to said delivery tube in order to form a main duct for the inflow of said steam. 3. The device according to claim 1, wherein between the passage channels for the liquid to be frothed there is located said at least one air intake channel, which extends starting from the upper edge of the end portion, so as to be able to be connected to the outside environment, and for much of the longitudinal extension of the central body, leading out into said at least one passage channel for the liquid to be frothed. 4. The device according to claim 3, comprising two of said passage channels for the liquid to be frothed, said air intake channel comprising a bifurcation for connecting to both of said passage channels for the liquid to be frothed, said outflow channel for the frothed liquid being connected, at a substantially central portion of said central body, to said two passage channels for the liquid to be frothed, a nozzle for injecting the steam that arrives from said main duct and said second mixing region being provided in the intersection between said rising channels and said outflow channel for the frothed liquid. 5. The device according to claim 1, wherein said outer casing is a substantially tubular element and is fitted detachably over said central body so that its inner surface delimits radially said passage channels for the liquid to be frothed, said outflow channel and said intake channel, said central body being fixed to said outer casing by interference. 6. The device according to claim 1, wherein said central body is entirely made of rubber material. 7. The device according to claim 1, wherein said central body is partly made of rubber material and rigid plastics by means of bi-injection or co-molding processes, said rubber material being arranged at the regions where said central body interferes and forms a seal with said outer casing. 8. The device according to claim 1, wherein said central body is made of non-stick material. 9. The device according to claim 1, wherein said central body is provided monolithically. 10. The device according to claim 1, wherein said outer casing is made of plastics or of non-stick material. 11. The device according to claim 1, wherein said central body comprises a plurality of longitudinal ribs arranged in contact with said inner surface of said outer casing so as to isolate said at least one channel for the passage of the liquid to be frothed from said outflow channel for the frothed liquid. 12. The device according to claim 11, wherein said air intake channel is formed by one of said plurality of longitudinal grooves provided along an outer surface of said central body to keep said air intake channel separate and isolated from said outflow channel for the frothed liquid.
