Abstract
With a method for heating in particular milk or milk foam, in which the milk or the milk/air mixture is conveyed through a passage opening and hot steam is conveyed through at least one steam line transversely into this passage opening. The passage opening and the at least one inlet opening opening transversely into the steam line, the steam pressure in this and the pressure and the pressure in the passage opening with flowing milk or milk/air mixture are so coordinated that the hot steam at the at least one transverse inlet opening condenses in the passage opening directly on contact with the milk or the milk/air mixture. Consequently the additional energy produced by the phase change from steam to condensate water is transmitted directly as heat to the heat in the milk or the milk/air mixture.
