Abstract
A device for warming up, in a bar or at home, milk taken from a container 21 and pushed by a pump 23 into a heat exchanger 1, where the milk circuit, consisting in a coil 3 or the like, is immersed into the heating liquid for leading the same, under pressure, to outlet nozzles provided with counterboring shapes 105 and 105' for the spout for the mixing with the atmospheric air taken, by depression, from a small tube 19 so as to determine the outflow of warm foamy milk.
