A method for producing a coffee beverage in a coffee machine including: a brewing device having a brewing chamber that receives ground coffee and includes a fluid inlet and a fluid outlet; a fluid system having a fluid feed line connected to the inlet and a fluid conveyor conveying a heated fluid through the feed line. The method includes: (a) introducing ground coffee into the chamber, (b) conveying heated fluid through the feed line into the chamber for brewing the ground coffee in the chamber and dispensing the beverage through the fluid outlet. Before step (a), heated fluid is fed through the feed line into the chamber and at least a part of this heated fluid is dispensed through a drainage outlet separate from the fluid outlet and fluidly communicating with the chamber and/or the feed line, to preheat the feed line and the brewing device before beverage preparation.

Device for heating and emulsifying beverages includes a pump (2), an air and water meeting zone (10), a device for producing steam, and a first conduit (5) for steam mixed with air that communicates with a steam wand (6) adapted to be immersed into a beverage (7) to be heated and emulsified. The device for producing steam includes an instant steam generator (4). The meeting zone (10) is positioned before the instant steam generator (4).

The invention provides a water-injection chamber for capsule coffee machines that makes it possible to regulate and maintain constant a predetermined temperature of the water to be injected into the coffee capsule, also facilitating the adjustment of the input flow of hot water into the brewing chamber of said coffee machines, making it possible to adjust the temperature and the flow of water to be injected into a capsule according to the specific needs of each capsule without needing to modify or install new elements that increase the production cost and complicate the manufacturing process.

A modular brewing system is described for providing hot water and managing power to multiple brew tower modules using a single centralized boiler and power management module so as to limit the number of high-power circuits required in a coffeehouse or store. The boiler and power management module manages power of components of the centralized boiler assembly and any brew tower modules connected thereto, including the boiler heaters, the grinder motors, and the brew chamber heaters.

A beverage-making machine includes: a housing; a fluid reservoir mounted to the housing; a first pump fluidly connected with the water reservoir; a heating unit comprising a conduit having an upper end and a lower end, the lower end of the conduit fluidly connected with the first pump, the conduit configured and arranged to rise monotonically from lower end to upper end; and a brew station having a brew basket with an inlet fluidly connected with the upper end of the conduit and an outlet, and further having a receptacle platform positioned to receive fluid from the outlet.

A beverage supply apparatus 100 includes milk tank 3, milk flow path L3, pump 7 for delivering a beverage, air flow path L6, pump 9 for supplying air configured to be capable of changing the discharge flow rate, release path L7 for discharging air flowing through air flow path L6 to the outside, on-off valve V7, first throttle part 16, and second throttle part 17. One end of release path L7 is connected to release point Z8 in air flow path L6, and the other end is open to the outside. On-off valve V7 is disposed in a flow path extending between release point Z8 and pump 9 in air flow path L6, and opens and closes this flow path. Throttle part 16 is disposed in a flow path extending downstream of release point Z8 in air flow path L6, and throttle part 17 is disposed in release path L7.

An automatic machine for preparing beverages, in particular American coffee, including a unit to feed the coffee powder, a mobile infusion unit having an infusion cylinder which delimits an infusion chamber, and a hydraulic circuit configured to heat the water for the infusion and feed it to the infusion chamber, where the infusion unit has an expulsion piston slidable inside the infusion cylinder and delimiting at the lower part the infusion chamber, and a valve device provided with a valve body and a closing piston which can engage with the infusion cylinder in order to close the infusion chamber.

The present invention relates to a sanitization unit (1) for sanitizing a liquid delivered to prepare a beverage. The sanitization unit (1) comprises an irradiation chamber (2) to receive liquid. The irradiation chamber (2) comprises: i) a liquid inlet (10) for introducing the liquid into the 5 irradiation chamber (2) and ii) a liquid outlet (12) for discharging the introduced liquid out of the irradiation chamber (2). An irradiation device (4) is configured to sanitize the liquid in the irradiation chamber (2). The liquid outlet (12) comprises a flow restrictor (12.1) to restrict a liquid flow when the pressure difference across the flow restrictor (12.1) is below a predetermined threshold, and to allow for a liquid flow with a higher flow rate when this pressure difference is equal to or greater than the predetermined threshold.

A steam production system for professional coffee machines includes a nozzle; a boiler for producing steam in flow communication with a water source and the nozzle. The boiler is equipped with an independent heating device for the initial production of steam. The system further includes a heating assembly to instantaneously produce steam in flow communication with the boiler and/or the nozzle. The heating assembly includes an electric heating element; a heat exchanger associated with the electric heating element; and a water passage circuit associated with the heat exchanger which has an inlet joined to a water supply source or to a duct arriving from the latter and an outlet of the produced steam connected to the boiler and/or to the nozzle. The system also includes a programmable electronic unit operatively connected to the boiler and to the heating assembly to ensure the supply of steam to the nozzle.

A beverage preparation machine having an inlet arrangement and a gasket arrangement is provided, where the inlet arrangement is configured with a plurality of inlet ports to deliver liquid to a beverage cartridge. The gasket arrangement may include a plurality of openings, wherein each of the plurality of inlet ports is received within one of the plurality of openings. The gasket arrangement may be integrally formed and may include one or more ribs disposed about each of the plurality of openings. A perimeter rib may extend along a perimeter of the gasket arrangement.
