The present invention relates to a capsule system for preparing beverages by centrifugation of a capsule (1) in a centrifuging brewing device comprising: a centrifuging brewing device comprising control means (25) capable of operating the device in centrifugation by controlling the beverage flow rate and/or the volume of the beverage, and a capsule to be inserted in the brewing device wherein the capsule is designed to form, alone or in cooperation with the centrifuging brewing device, a flow restriction or flow restriction valve which provides a backpressure for the centrifuged liquid, wherein the control means (25) of the device selectively adjusts the rotational centrifugation speeds of the inserted capsule (1) and/or the volume of injected liquid in the capsule as a function of the exerted backpressure by the restriction or restriction valve.

The invention relates to a capsule (1, 1) designed for insertion in a beverage production device (100) for preparing a beverage from a substance contained in the capsule (1, 1) by introducing liquid into the capsule (1,1) and, optionally, by passing the so introduced liquid through the substance using centrifugal forces. The capsule (1,1) comprises: a body (2) defining an enclosure for containing an amount of beverage substance, the body (2) comprising a bottom end and an open end; a flange-like rim (22) extending outwardly from the body (2); an upper wall (3, 3) attached to the flange-like rim (22) to cover an opening (21) of the body (2) at its open end; and an annular ring (4, 4) that is separately provided and clampable between the flange-like rim (22) and the beverage production device (100) when the capsule (1, 1) is inserted in the beverage production device (1, 1) for preparing the beverage. The annular ring (4, 4) is made at least partly of a biodegradable and/or compostable material.

Device for foaming a liquid comprising a mixing unit (30). The mixing unit (30) comprises a first element (31) having an inner surface (33), a second element (34) having an outer surface (35), a gap (36) between the inner surface (33) of the first element (31) and the outer surface (35) of the second element (34), a first opening (37) and a second opening (38) connected through the gap (36). At least one of the first element (31) or the second element (34) is rotatable about an axis of rotation (AR) with respect to the other one. The inner surface (33) and the outer surface (35) are symmetric with respect to a common axis of symmetry (AH, AW), coincident with the axis of rotation (AR), and have circular sections, perpendicularly to the axis of symmetry, having diameters which increase going in a direction along the axis of symmetry (AH, AW).

A centrifugal device for brewing coffee includes a spinning assembly, the spinning assembly includes a piston element, a cylinder element including a peripheral wall, a filter, a motor and a spindle connected to the motor. The piston element includes a nut. During centrifugal rotation, the piston element is in a coffee brewing position, and during the centrifugal rotation the piston element is rotated by the spindle via the action on the nut and is pressed against the upper rim, where a centrifugal force is created which forms a bed of coffee against the peripheral wall and which drives hot water through the bed of coffee and through the filter. A stopping device includes an engagement member and an actuator, the engagement member being movable by the actuator between an engaged position engaging the piston element of the spinning assembly and a disengaged position.

A coffee making appliance includes a housing having a base for supporting a container configured to receive brewed coffee and a reservoir for receiving water to be heated. A hopper is configured to receive a quantity of whole coffee beans and is positioned adjacent a grinder that is itself configured to transform the whole coffee beans into ground coffee. A passageway is formed in the housing for channeling the ground coffee from the grinder to a brewing chamber. A pump configured to supply the water from said reservoir to said brewing chamber via a brew path and the brew path then directs said heated water over the passageway, thereby cleaning the passageway of particulates of the ground coffee.
