Beverage capsule for preparing a beverage by centrifugation in a beverage preparation device

Beverage capsule for preparing a beverage in a beverage preparation device from a capsule containing beverage ingredients by passing water through the ingredients contained in the capsule using centrifugal forces:

• the device comprising a driver for rotating the capsule around an axis of rotation, a capsule holder for receiving the capsule and a water injector for injecting water in the capsule, the device further comprising a resilient valve for engaging a valve engaging portion of the capsule, the valve comprising a pressing ring;
• the capsule comprising a body and a lid defining a compartment containing beverage ingredients and a valve engaging portion designed for being inserted between the capsule holder and the valve of the device;
• wherein the capsule comprises an outlet structure forming beverage flow restriction passages of defined cross-section in the capsule obtained at such and/or as a result of the insertion of the valve engaging portion between the capsule holder and the pressing ring of the valve;
• and
• wherein the valve engaging portion of the capsule has an axial dimension such that, before the extraction of the beverage from the capsule, the pressing ring of the valve is stressed by the valve engaging portion to an axial force and/or axial distance such that, during the extraction by rotating the capsule in the device, the pressing ring no longer moves by the pressure of the centrifuged beverage on the valve within the operational rotational speed and the flow of beverage is only funneled through the flow restriction passages.
