Abstract: The invention relates to a brewing unit (01) for a beverage preparation device for substrate portions, including a carrier (04) and a brewing chamber (11), which has at least two brewing chamber halves (02, 03), which are movable relative to one another in a first direction (03.

Abstract: The invention relates to a brewing unit (01) for a beverage preparation device for substrate portions, in particular for a coffee machine for pre-portioned coffee units, the brewing unit (01) having a support (04) and a brewing chamber (11) having at least two brewing-chamber halves (02, 03) configured to move relative to each other in a first direction (03.1), and preferably a mechanical drive for moving the brewing-chamber halves (02, 03) between an open position, in which the brewing-chamber halves (02, 03) are spaced apart from each other, and a closed position, in which the brewing-chamber halves (02, 03) are in contact with each other in the area of contact surfaces (09, 10), in particular by moving one brewing-chamber half (03) relative to the support (04).

Abstract: The invention relates to a brewing unit (01) for a beverage preparation device, in particular for a coffee machine for substrate portions, in particular pre-portioned coffee units, comprising a support (04) and a brewing chamber (11), which has at least two brewing chamber halves (02, 03) that can be moved relative to each other in a first direction (05) and which comprises a movable holding structure (08) that is arranged so as to contact/support a fixed substrate portion such that, depending on the relative arrangement of the brewing chamber halves (02, 03), the holding structure (08) can be moved between positions between the brewing chamber halves (02, 03) and above the brewing chamber halves (02, 03).

Abstract: Brewing unit (3) for a beverage preparation machine with a first brewing chamber half (11) and a second brewing chamber half (12), which are arranged to be movable relative to one another from a closed position for forming a closed brewing chamber into an open position in which a capsule (60) can be inserted into the brewing chamber. The brewing unit (3) has at least one, preferably two, holding means (38) which hold a capsule (60) in an intermediate position in the open position between the first and second brewing chamber halves (11, 12) when the capsule (60) is inserted and release it when the brewing chamber is closed. Before release by the holding means (38), the first and second brewing chamber halves (11, 12) are spaced apart in such a way that the brewing chamber halves (11, 12) cannot grip a capsule (60).

Abstract: Brewing unit of a beverage preparation machine with a brewing chamber (10) and a brewing chamber surface (15), wherein the brewing chamber (10) is designed to be substantially rotationally symmetrical with respect to an axis (16) directed from a first brewing chamber half (11) to a second brewing chamber half (12). The brewing chamber (10) has a maximum axial extension (17) in the direction of the axis (16), which is smaller than the largest diameter (18) transverse to the axis (16). Furthermore, the brewing chamber (10) has a thickness (19) in the area of the axis (16) which is equal to or smaller than the axial expansion (17).

Abstract: The present invention relates to a brewing apparatus (1) for making a beverage from a single-serve capsule (2), wherein the brewing apparatus (1) has a first brewing-chamber element (3), a second brewing-chamber element (4) and a sealing device (5), wherein the first brewing-chamber element (3) can be moved along a central axis (12) between a loading position, in which the first and the second brewing-chamber elements (3, 4) are spaced apart from one another, and an operating position, in which the first and the second brewing-chamber elements (3, 4) have been moved towards one another to form a substantially closed brewing chamber (10), wherein, in the operating position, the sealing device (5) is arranged between the first and the second brewing-chamber elements (3, 4), wherein the first or second brewing-chamber element (3, 4) has a liquid-feeding device (6) for injecting liquid into a single-serve capsule (2) located in the brewing chamber (10).
