Coffee makers with features for rapid and/or multiple extraction processes, and associated systems and methods, are disclosed. A representative method for brewing coffee includes placing ground coffee on a filter element of a brew chamber, directing heated water into the brew chamber and in contact with the ground coffee and, during a first phase, brewing coffee in the brew chamber without subjecting the coffee to a pressure differential of at least 150 torr between the brew chamber and a coffee chamber to which the brew chamber is coupled, the coffee chamber having a capacity of 200 mL or more. The representative method further includes, during a second phase, extracting the coffee from the brew chamber through the filter element and into the coffee chamber via a pressure differential of at least 150 torr between the brew chamber and the coffee chamber.

A system for detecting the presence of a filter holder in a dispensing assembly of a coffee machine includes: a ring with an internal groove, a filter holder with a tab coupled with the groove and a proximity sensor. The groove has a semi-annular shape and is configured in such a way to receive the tab of the filter holder in bayonet coupling mode, wherein the filter holder is translated and rotated. The ring has a rotation stopper suitable for stopping the rotation of the filter holder in the ring in a stop point. The proximity sensor passes through the ring and finishes in the stop point of the groove of the ring.

The invention relates to a coffee tamper. More specifically, the invention relates to a device for tamping coffee grounds in a basket or portafilter of an espresso machine, by which device a reproducible pressure is applied to the coffee grounds and which is designed to reduce occupational-related diseases among professional users, like e.g. baristas.

A coffee machine includes a weighing system to measure the weight of the liquid coffee extracted in a cup and a coffee grinding machine having a weight system to measure the weight of the ground coffee dispensed in a filter-holder. The coffee machine has a control unit provided with a memory, wherein infusion ratios for different types of coffees are saved and the coffee grinding machine includes a control unit operatively connected to the control unit of the coffee machine to send information about the weight of the ground coffee contained in the filter-holder. The control unit of the coffee machine uses the information received from the coffee grinding machine to extract a coffee that satisfies an infusion ratio selected by the operator.

Apparatuses, systems, and methods for brewing a desired portion of a beverage, such as a single-cup portion of coffee, are provided. The system can include one or more hopper assemblies configured to provide a controlled dose of beverage material to a brew chamber. The system can also include a water input system configured to wet the ground beverage material as the grinds enter the brew chamber and substantially prevent steam from reaching grinder components of the system. Further, the system can include an automatic cleaning mechanism such that a user does not need to manually clean components of a brewing machine between brew cycles.

A brewing device for a machine for preparing beverages like coffee or tea has a brewing chamber with a longitudinal axis, a frame having two walls arranged on opposite sides of the brewing chamber, and a fastening device. The fastening device is configured to releasably couple the brewing device to a support body in the beverage preparation machine and includes a lever release device hinged to the frame to rotate about an axis transverse to the longitudinal axis between a normal coupling position, in which the lever release device stably holds the brewing device on the support body, and a release position, in which the lever release device allows the brewing device to be released from, or mounted on, the support body.

The fastening device is configured to releasably couple the brewing device to a support body in the beverage preparation machine and comprises a lever release device hinged to the frame to rotate about an axis transverse to the longitudinal axis between a normal coupling position, in which the lever release device stably holds the brewing device on the support body, and a release position, in which the lever release device allows the brewing device to be released from, or mounted on, the support body.

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.

The infusion unit comprises a receptacle (25, 27) for receiving at least one ingredient in bulk form for the preparation of a beverage, as well as a brewing piston (33) arranged for insertion in the receptacle and forming a brewing chamber therewith. The brewing piston (33) is provided with a sealing arrangement (35) for sliding and sealing engagement with an inner wall of the receptacle when the brewing piston is in the receptacle. A hydraulic actuator (51) controls the movement of the brewing piston (33) so as to adjust the volume of the brewing chamber by moving the brewing piston in a brewing position inside the receptacle. A hot water delivery circuit (39) is further provided, for delivering hot water in the interior of the brewing chamber and performing a brewing cycle.

The invention relates to a modular brewing unit for a coffee machine, comprising a brewing part and a drive part, which are arranged parallel one beside the other in a common frame, wherein the brewing part, arranged concentrically along a common first axis, has an upper piston, a lower piston and, between the two pistons, a brewing cylinder with a cylindrical bore for accommodating the two pistons, a brewing chamber being formed in the process, and wherein the drive part comprises a spindle which extends along a drive axis, parallel to the first axis, is mounted in the frame such that it can be rotated about said drive axis and is in engagement with the brewing cylinder and the lower piston such that, during a brewing cycle, upon rotation of the spindle, the brewing cylinder and the lower piston are displaced along the first axis relative to the upper piston, which is fixed in the frame. Different brewing units are realized in a simplified manner in that the drive part can be combined with brewing parts of different designs in order to provide for different brewing conditions.
