A coffee machine is for preparing an espresso coffee drink, but it also enables filtered coffee to be produced. An external water delivery nozzle is provided, and it provides water to a coffee jug comprising a filter holder for holding a coffee filter and contained coffee grinds. The coffee jug and the external water delivery nozzle can be coupled and decoupled.

A device for creating infused beverages that includes a solvent flow management system having a pump body with a pump bore defining a pump interior volume, a piston disposed within the pump interior volume and in a fluidically sealed configuration with the pump bore, and a pump drive system operably coupled to the piston to generate a piston translation path. The device also includes a solvent-flow conduit and in fluid communication with the pump interior volume and a brewing chamber, an outlet, and a flow control valve, wherein the pump drive system is operably configured to selectively drive the piston along the piston translation path, when the flow control valve is in a selectively closed position, to induce a negative pressure and the flow of fluid through a solute housed in the brewing chamber, downstream and through the solvent-flow conduit, and into the pump interior volume.

An infuser unit (1) for a coffee machine, comprising a closing piston (3) and an infusion cylinder (2) which are axially movable selectively or in combination for reciprocal engagement and disengagement so as to close and open an infusion chamber inside the infusion cylinder (2), in which a dose of coffee can be positioned, an ejection piston (5) engaged in the infusion cylinder (2) and axially movable in the infusion cylinder (2) so as to expel the spent coffee grounds, a first radial hydraulic sealing means between said closing piston (3) and said infusion cylinder (2), and a second radial hydraulic sealing means between said infusion cylinder (2) and said ejection piston (5), at least one between the first hydraulic sealing means and the second hydraulic sealing means comprising at least one seal (100, 101) having an anti-friction surface coating made of a material free of grease and lubricating oils and compatible with use in contact with foodstuffs and drinking water.

An espresso coffee machine including a main boiler, a dispensing group, a secondary boiler, a main water inlet circuit, hydraulically connected to the main boiler and to each secondary boiler and an electronic control unit, where the main water inlet circuit has a booster pump, the machine further includes a pressure sensor, a bypass circuit hydraulically, and a two-way proportional valve configured to recirculate a part of delivery flow of the booster pump on the main water inlet circuit and upstream of the booster pump, in order to maintain a certain coffee extraction pressure value in each dispensing group set in real time by the pressure sensor.

Devices and methods for infusing liquids and/or brewing beverages are described. The present invention relates to an apparatus for brewing beverages having a vessel, said vessel including a sealable chamber for holding a brewing material and a liquid, and a filter assembly connected to the sealable chamber; a liquid supply and conduit for introducing at least a portion of said liquid supply into said sealable chamber; and a vacuum source and conduit for reducing pressure in said sealable chamber.

An apparatus for production of French press style coffee via a process to immerse and steep coffee grounds in heated water in a non-oil-absorbing environment. Filtering a finished beverage from the steeped mixture through a microperforated non-oil-absorbing filter, where microperforations are sized to achieve sediments levels equivalent to or less than that of traditional French press, and filtration rate is enhanced via any combination of vibratory energy, air pressure, and air flow to the brewed mixture. The microperforated filter may be permanent and reusable, or may be disposable. The disposable filter is preferably made from flexible aluminum foil and recyclable. The apparatus and method support modification of filter size, microperforation size, perforation density, air pressure, air flow and vibratory action to vary beverage filtration rate and finished beverage composition.
