The valve may include a hollow body that includes: a steam inlet connection; a steam outlet connection; a condensation water drain connection; a cartridge configured to perform angular movements about a longitudinal axis; and a control knob, connected to the cartridge to impart the angular movements thereto.

Abstract: A grinder-doser may include: grinding members configured to receive and grind coffee beans and configured to deliver ground coffee into a dispensing conduit; a compacting member including a dispensing opening aligned with the dispensing conduit; a slide guide; and a sliding block configured to slide along the slide guide for selectively superimposing a first or second opening to the dispensing opening, allowing the ground coffee to move from the dispensing conduit to the dispensing opening via the first or second opening. The first opening may be reversibly closed by a closure element. The closure element may include a flexible sheet. The closure element may be configured to allow the ground coffee to move from the dispensing conduit to the dispensing opening as a thrust limit value exerted by the ground coffee on the closure element is exceeded. Thrust exerted by the ground coffee may cause the closure element to bend.

The device can include: a mechanism for axially moving the stationary grinding wheel; an electric motor, coupled to the mechanism, for actuating the mechanism; and a way to stop the electric motor as soon as a contact state is detected between the stationary and rotating grinding wheels.

Abstract: A grinder for beans of plant-based products, for example roasted coffee beans, includes a grinding chamber defined by a cylindrical wall and a pair of opposed grinding wheels located in the grinding chamber. At least one of the pair of opposed grinding wheels rotates. The grinder further includes an electric motor for driving the rotating grinding wheel and a first cooling duct extending in the cylindrical wall between a first inlet and a first outlet. A tubular circuit connected to the first cooling duct includes a pump for circulating fluid, a heat dissipater, at least one valve member, and an electronic control unit for actuating the pump and for turning on the heat dissipater according to a temperature sensed by a temperature sensor.

Abstract: A grinding chamber of a grinding device for vegetal products suitable to form beverages includes, in its interior, a pair of grinders axially overlapping each other, one of which is rotatable with respect to the other which is kept stationary, a grinder support at least for the rotatable grinder, a motor member connected to the grinder support for setting the rotatable grinder in rotation. The grinding chamber is formed by a first bottom wall, perpendicular to the axis of rotation of the rotatable grinder, adjacent and below the support thereof, and at least a second cylindrical wall, connected axially to the first wall at the peripheral boundary thereof. The grinding chamber also includes a first opening for introducing the product to be ground and with a second opening for discharging the ground product. A labyrinth is provided between the peripheral boundary of the first wall and the grinder support.

Abstract: A method of controlling dispensing of doses of coffee grounds, the machine comprising a grinding device which is configured to grind coffee beans, a conduit, having an inlet in communication with the grinding device for receiving coffee grounds, and an outlet, a closure member which is adapted to be removed between an open position for the coffee grounds to be discharged from the conduit through the outlet, and a closed position for closing the outlet, and a coffee grounds weight sensor, which is configured to generate signals representative of the weight of coffee grounds built-up in the dispensing conduit when the closure member is in the closed position.

Abstract: A dosing device dispenses predetermined doses of ground coffee into a filter holder of an espresso coffee machine. The dosing device includes a carousel body formed by plural compartments sized to hold respective p doses of ground coffee. Each compartment includes a top opening and a bottom provided with members for opening and closing thereof. The carousel body can be displaced between a first position, in which the top of one of the compartments is at a discharge conduit of ground coffee and a second position in which the bottom of the compartment is positioned above the filter holder. The dosing device disclosure can arrange doses of ground coffee, different from each other, preparing different types of beverage, within respective containment compartments, select the dose for the beverage, select the compartment that contains it, move the compartment to the filter holder, and supply the selected dose to the filter holder.

Abstract: A device for continuous heating of fluids, using steam, includes a first tubular circuit, having one inlet and one outlet, in which to fluid or mixture of liquids with gases to be heated is circulated, and a second tubular circuit in which the heating steam is circulated. The first tubular circuit comprises a section that is helically wound around a section of the axial length of a hollow first cylindrical body, closed at both ends. The device further comprises a hollow second hollow cylindrical body in which said first cylindrical body and said helically wound section are coaxially housed.
