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.
A mixing head for producing heated milk comprising a steam feed which feeds steam to the mixing head, a milk inlet, a mixing area where the steam feed and milk inlet join and wherein the steam from the steam feed and the milk from the milk inlet combine to form a mixture, an outlet nozzle for draining the mixture from the mixing head, a rinsing medium supply, a milk supply, and a mechanism for bringing the milk inlet into fluid connection with either the rinsing medium supply or the milk supply, such that milk or a rinsing medium can enter the mixing head at the milk inlet, and when the rinsing medium enters the mixing head it cleans any residual milk from the milk inlet.
A mixing head for producing heated milk comprising a steam feed which feeds steam to the mixing head, a milk inlet, a mixing area where the steam feed and milk inlet join and wherein the steam from the steam feed and the milk from the milk inlet combine and to form an emulsified mixture, an outlet nozzle for draining the mixture from the mixing head, a milk supply receptacle, and a mechanism for selectively bringing the outlet nozzle into a position in which any fluid leaving the outlet nozzle is transferred actively or passively into the milk supply receptacle such that any residual milk can be removed from the mixing head.
A device for producing heated milk comprising a housing and a mixing head comprising a steam feed which feeds steam to the mixing head, a milk inlet, a mixing area where the steam feed and milk inlet join and wherein the steam from the steam feed and the milk from the milk inlet combine and to form a mixture, an outlet nozzle for draining the mixture from the mixing head, and a transfer mechanism for moving the outlet nozzle to either a retracted position where the mixing head outlet nozzle are configured and positioned to be cleaned or rinsed, or a product delivery position in which the outlet nozzle protrudes from a front wall of the housing to deliver the mixture.
