A capsule for preparing a beverage or liquid food from a substance, in a centrifugal brewing unit, by passing water through the substance contained in the capsule by using brewing centrifugal forces. The capsule includes an enclosure containing a predetermined dose of substance, an opening member which opens the capsule under the centrifugal effect to allow the brewed liquid to leave the capsule. The capsule may also include externally driving the capsule in a centrifugal brewing device wherein the capsule includes a structure configured to offer resistance to torque during rotation of the capsule for maintaining the capsule in a reference rotational position.

1. A capsule for preparing a beverage or liquid food in a centrifugal brewing device from a food substance contained in the capsule by passing water through the substance using centrifugal brewing forces, the capsule comprising: an enclosure containing a predetermined dose of substance, the enclosure comprising a body for holding the food substance, the body having an upper rim, and a lid or membrane for closing the body at the upper rim, andmeans for engaging the capsule to external rotational driving means of a centrifugal brewing device, the engaging means comprising a gripping structure of a toothed structure or a series of protrusions or recessed elements on an outer surface of the enclosure, with the gripping structure having a shape that is complementary to an engaging structure of the driving means so that the capsule gripping structure locks into the engaging structure of the driving means to fulfil both a gearing function for driving the capsule at high speeds in rotation and a safety function for ensuring that only capsules with the gripping structure can be used and brewed successfully in the centrifugal brewing device, wherein the engaging means also offers resistance to torque during rotation of the capsule for maintaining the capsule in a reference rotational position. 2. The capsule of claim 1, wherein the gripping structure is a toothed structure associated with the capsule. 3. The capsule of claim 1, which further comprises radial opening means for allowing the beverage or liquid food to leave the capsule, with the opening means forming or creating at least one radial outlet by movement of the beverage or liquid food due to centrifugal forces when the capsule is driven in rotation. 4. The capsule of claim 2, wherein the capsule has a flared design and a series of spaced radial outlets positioned or created at or close to the larger side of the flared design. 5. The capsule of claim 2, wherein the opening means opens for creating the at least one outlet by movement of the beverage or liquid food due to centrifugal forces when the capsule is driven in rotation which forces exert a flexure on at least one deflectable portion of the capsule, with the deflectable portion being an elastic lip acting in closure on a surface of the capsule or inserted in a peripheral cavity of the capsule. 6. The capsule of claim 1, which further comprises an injection tubular portion having a water inlet on a surface of the capsule and a water outlet communicating internally in the capsule, wherein the water outlet is close to or in contact with the bottom of the capsule. 7. The capsule of claim 1, the capsule contains a dose of substance for preparing one or two servings of beverage and the substance is ground coffee powder, soluble coffee, or tea. 8. The capsule of claim 1 wherein the lid or membrane includes opening means which opens due to pressure experienced when the liquid is centrifuged to create a passage that allows the beverage or liquid food pass to leave the capsule. 9. The capsule of claim 8, wherein the opening means comprises a resilient valve. 10. The capsule of claim 8, wherein the opening means comprises at least one radial deflectable lip integral to a wall of the capsule. 11. The capsule of claim 10, wherein the deflectable lip is part of the lid or body of the capsule. 12. The capsule of claim 11, wherein the deflectable lip is present in a peripheral groove of the lid or body. 13. The capsule of claim 1, wherein the tooth structure comprises a series of teeth positioned below the rim of the body of the capsule. 14. A capsule for preparing a beverage or liquid food by passing water through a substance contained in the capsule by using brewing centrifugal forces comprising: an enclosure comprising a cup-shaped body having a sidewall, a bottom wall and a lid sealed to the sidewall, the enclosure containing a predetermined dose of substance, anda series of slits located at the periphery of the sealed lid of the enclosure that allows the beverage or liquid food to leave the capsule when centrifugal forces are exerted in the capsule wherein the outlet(s) retain solid particles in the capsulewherein the enclosure includes a sealing membrane covering the series of slits to make the capsule gas-tight before use. 15. The capsule of claim 14, wherein the capsule has a flared cup-shaped body and comprises a lid connected to the flared cup-shaped body, with the at least one outlet placed at or close to the larger side of the flared cup-shaped body of the capsule. 16. A system for preparing a beverage or liquid food from a food substance contained in a capsule by passing water through the substance in the capsule, the system comprising: a device comprising: water feed means for introducing water into the capsule, andmeans for centrifugally rotating the capsule to force the water to flow through the substance in the capsule in a centrifugal flow path to prepare the beverage or liquid food; andreferencing means for positioning and referencing the capsule in a removable manner in the device and in operational relationship with the water feed means and along an axis of rotation in the centrifugal rotating means; anda capsule comprising a cup-shaped body having a sidewall, a bottom wall, a lid or membrane sealed to the sidewall and means for connecting the capsule to the driving means in a removable manner wherein the connecting means comprise a gripping structure of a toothed structure or a series of protrusions or recessed elements on an outer surface of the enclosure, with the gripping structure having a shape that is complementary to an engaging structure present on the driving means so that the capsule gripping structure locks into the engaging structure of the driving means to fulfil both a gearing function for driving the capsule at high speeds in rotation and a safety function for ensuring that only capsules with the gripping structure can be used and brewed successfully in the centrifugal brewing device, wherein the engaging means also offers resistance to torque during rotation of the capsule for maintaining the capsule in a reference rotational position. 17. The system according to claim 16, wherein the connecting means of the capsule comprises a toothed structure associated with the capsule. 18. The system according to claim 16, wherein the capsule has a plastic lid resiliably attached to a cup-shaped body, wherein the lid and body are attached via a radial deflectable sealing means which opens when experiencing centrifugal forces to let the beverage or food liquid leave the capsule. 19. The system according to claim 18, wherein the deflectable sealing means comprises at least one peripheral plastic lip engaging in a seat. 20. The system according to claim 16, wherein the capsule has a plastic lid welded on a cup-shaped body and wherein radial outlets are provided on the lid or body for allowing the beverage or liquid food to leave the capsule. 21. The capsule of claim 14, further comprising means for engaging the capsule to external rotational driving means of a centrifugal brewing device, the engaging means comprising a gripping structure of a toothed structure or a series of elements in relief or hollow on an outer surface of the enclosure, with the gripping structure having a shape that is complementary to an engaging structure of the driving means so that the capsule gripping structure frictionally engages or receives the engaging structure of the driving means to fulfil both a gearing function for driving the capsule at high speeds in rotation and a safety function for ensuring that only capsules with the gripping structure can be used and brewed successfully in the centrifugal brewing device, wherein the engaging means also offers resistance to torque during rotation of the capsule for maintaining the capsule in a reference rotational position. 22. The capsule of claim 16, wherein the tooth structure comprises a series of teeth positioned below the rim of the body of the capsule.
