A user interface is configured to cause the coupling device to tight-couple and uncouple and/or a beverage delivery to start and stop in response to sensed actions or forces.

Abstract: An electromagnetic induction continuous-flow milk heater for an automatic beverage vending machine has a tubular body that includes an inlet and an outlet. Milk to be heated into the tubular body. Heated milk flows out of the tubular body through the outlet. An electrical winding is wound around the tubular body that can be electrically powered to generate an electromagnetic induction field. The tubular body is made of an electrically conductive material to enable heating by electromagnetic induction from the electromagnetic induction field. The heater can include an insert housed inside the tubular body that extends along a longitudinal axis of the tubular body. The tubular body and the insert delimit, at least between an external surface of the insert and an internal surface of the tubular body, a helical flow channel for the milk, which extends in a helix around the longitudinal axis.

Abstract: A milk frother/heater for a milk supply circuit in a beverage vending machine has a hollow body and integrally has a first appendage defining a milk inlet to receive smooth milk or a milk-air mixture, a second appendage defining a steam inlet to receive steam, and a third appendage defining a milk outlet to deliver milk. The body internally defines a mixing chamber, and the milk inlet, the steam inlet and the milk outlet internally define a milk inlet passage, a steam inlet passage, and a milk outlet passage, respectively, fluidly communicating with the mixing chamber. The mixing chamber has an axis extending from a first closed axial end to a second axial end where the steam inlet passage and the milk outlet passage converge. The milk inlet passage converges at the second axial end or merges with the steam inlet passage upstream from the mixing chamber.

Abstract: The present disclosure is for an electronic control system for a brewing device for a machine for preparing beverages, in particular coffee or tea. The brewing device comprises a brewing chamber having an opening through which a material to be brewed may be loaded and discharged; a closing body movable away from and towards a sealed closing position of the opening angularly spaced apart from the closing position, through an intermediate ejection position, in which the closing body is raised with respect to the closing position along the longitudinal axis of the brewing chamber; a piston slidably mounted in the brewing chamber in a position axially opposite the closing body; a first electric actuating device for the movement of the closing body; and a second electric actuating device for the movement of the piston.

Abstract: An electromagnetic induction continuous-flow water heater, in particular an automatic beverage vending machine is provided. The heater includes: a tubular body having a longitudinal axis and at least one inlet, configured to receive water to be heated and to feed it, in use, into the tubular body, and an outlet, through which the heated water flows out of the tubular body; and an electrical winding wound around the tubular body and electrically powerable to generate an electromagnetic induction field. The tubular body is made of an electrically conductive material heated by electromagnetic induction. The heater further includes an insert housed inside the tubular body and extending along the longitudinal axis with the tubular body and the insert delimit at least between an external surface of the insert and an internal surface of the tubular body, a helical flow channel for the water, which extends helically around the longitudinal axis.

Abstract: A brewing device is used for preparing beverages like in particular coffee or tea. The brewing device includes a brewing chamber with an opening for loading/unloading a brewing material, a piston slidably mounted in the brewing chamber and an electronic control unit. The electronic control unit is programmed to cause the piston to move among a loading configuration, in which the brewing material is loadable in the brewing chamber, a compression configuration, in which the piston compacts the brewing material in the brewing chamber, and an expulsion configuration, in which the piston extracts the exhausted material from the brewing chamber. The electronic control unit is programmed to cause, in the loading configuration, the piston to lower from a higher position, corresponding to an initial loading configuration, to a lower position, corresponding to a final loading configuration.
