Abstract
A device for emulsifying and/or heating milk comprising a milk heater, a hermetically closed milk container, a mixer provided with a milk inlet, an air inlet and an outlet of a milk-based drink, a milk supply circuit comprising a connection conduit between the milk container and the milk inlet, and at least one air pump connected in delivery to a pressurization conduit of the milk container for pushing the pressurized milk towards the milk inlet, where a pressure adjustment means of said pressurization conduit is included which is used for adjusting the temperature of the milk.
Claims16
A device for emulsifying and/or heating milk comprising:
- a hermetically closed milk container configured to retain a volume of milk;
- a mixer comprising a milk inlet in fluid communication with the volume of milk configured to provide milk from the milk container to the mixer;
- an air inlet in fluid communication with the mixer configured to provide air to the mixer;
- a milk heater in fluid communication with the mixer configured to provide heated fluid to the mixer;
- an outlet in fluid communication with the mixer configured to dispense a milk-based drink;
- and
- a supply circuit supplying milk to said milk inlet, comprising:
- a connection conduit between said milk container and said milk inlet, and
- at least one air pump connected to a pressurization conduit of the milk container configured to provide pressurized milk towards said milk inlet,
- a pressure adjustment unit adjusting the pressure of said pressurization conduit, said pressure adjustment unit being used to adjust the temperature of the milk;
- and
- an electronic controller operatively connected to one or more electrically controlled components of the device to adjust a pressure of the pressurization conduit,
- wherein said air pump is an electric air pump, and said pressure adjustment unit of said pressurisation conduit comprises a delivery pressure sensor of said electric air pump connected to said electronic controller.
