    摘要： A device for heating and frothing milk which has a steam generator and a jet pump is provided. The jet pump has a steam inlet through which pressurized steam is injectable into the jet pump, a first suction inlet and a second suction inlet. The first suction inlet is configured to connect to a milk reservoir. An air inlet is connectable or connected to the second suction inlet of the jet pump for drawing air into the jet pump. A bypass valve is connected to the second suction inlet of the jet pump and has a bypass inlet. The bypass valve is switchable between a first position in which the second suction inlet of the jet pump is shut off from the steam generator, and a second position in which the second suction inlet is in fluid communication with the bypass inlet of the bypass valve for suction of steam.

    摘要： A motorized brewing unit for preparing beverages from a powdered product has a dispensing assembly having a first assembly part provided with a receptacle adapted to receive the powdered product, and a second assembly part, relative to which the first assembly part is movable between an open position and a closed position in which the first assembly part and the second assembly part are coupled to each other to define a brewing chamber therebetween. The motorized brewing unit has an electric motor that controls movement of the first assembly part between the open position and the closed position and a readout device that provides a digital image of the powdered product. The readout device has an optical sensor. The receptacle faces the optical sensor when the first assembly part is in a detection position, intermediate between the open position and the closed position.

    摘要： The device (1) comprises a steam generator (2, 4), a compressed-air generator (9, 11) and a dispensing wand (10) connected or adapted to be connected to the steam generator (2, 4) and the compressed-air generator (9, 11) and adapted to be introduced into a receptacle (R) containing the milk (M) to be heated and frothed. The dispensing wand (10) defines first and second conduits (21, 22) separate from each other and having respective separate inlets (10a, 10b) for connection to the steam generator (2, 4) and the compressed-air generator (9, 11), respectively, as well as respective separate outlets (10c, 23; 10d, 24) for dispensing during use a flow of steam and a flow of compressed air, respectively, within the milk (M) contained in the receptacle (R), said outlets (23, 24) being arranged such that the flows of steam and compressed air exiting therefrom intersect each other.

    摘要： A capsule for extraction of a beverage of the filter-coffee type has a capsule body (2), made of water-impermeable material, which defines a chamber (3), present inside which is a precursor of the beverage, comprising soluble coffee and roast and ground coffee. At least 51 wt % of the precursor is roast and ground coffee having a grain size expressed in x50 comprised between 350 and 800 μm, and the complement to 100 wt % of the precursor is soluble coffee having a grain size expressed in x50 comprised between 1000 and 5000 μm. The roast and ground coffee is laid out to form a first layer (GC) in the lower part of the capsule body (3), and the soluble coffee (SC) is laid out to form a second layer (SC) in the upper part of the capsule body, i.e., in a position corresponding to the inlet wall (5) and/or above the first layer (GC). The first layer of roast and ground coffee (GC) is pressed inside the capsule body (3), and the second layer of soluble coffee (SC) is present inside the capsule body (3) substantially unpressed.

    摘要： A machine for preparing beverages, in particular espresso coffee, comprises a hydraulic circuit including a brewing unit, a water tank, a pump having the inlet connected in fluid communication to the tank, and the outlet or delivery connected in fluid communication to the brewing unit. A normally closed one-way hydraulic valve, which is set between the pump and the brewing unit, enables a flow of water toward the brewing unit when the pressure of the water delivered by the pump exceeds a substantially predetermined threshold. There is a heating means for heating the water delivered by the pump. The machine has a normally open discharge valve having a main inlet (12IN), connected between the one-way hydraulic valve and the brewing unit, a main outlet, connected toward a discharge space, and an open/close member set between the main inlet and the main outlet, designed to assume an open condition and a closed condition, where it enables and prevents, respectively, a flow of fluid between the inlet and the outlet, with the open/close member being urged by a corresponding spring into the open condition. The discharge valve is a hydraulically driven valve, which includes a chamber for hydraulic driving of the open/close member, an auxiliary inlet of the driving chamber, connected to the delivery of the pump, and an auxiliary outlet of the driving chamber, connected to the brewing unit, in such a way that water forced by the pump passes through the driving chamber before reaching the brewing unit. The discharge valve has a further outlet of the driving chamber, connected in fluid communication to a device for spillage of water from the driving chamber, in particular towards one of the water tank and the inlet of the pump.
