Abstract
A mixing head for producing heated milk in the form of a froth or water-milk mixture. The mixing head includes a steam feed, a milk inlet, a mixing area where the steam feed and milk inlet join and the steam and milk combine, an outlet nozzle for draining the resulting mixture from the mixing head, a rinsing medium supply, a milk supply and a transfer mechanism that provides relative movement between the milk inlet and the rinsing medium supply or the milk supply for selectively bringing the milk inlet into fluid connection with the rinsing medium supply or the milk supply, such that milk or a rinsing medium, as desired, can enter the mixing head at the milk inlet.
