A method for preparing a liquid comestible from a cell by passing liquid through the substance using centrifugal forces, wherein gas contained in the cell is controllably purged from the cell as liquid fills the cell. In one embodiment, the method includes prewetting the substance in the cell by filling liquid in the cell and rotating the cell at a first rotational speed; and then extracting the liquid comestible from the cell in an extraction phase which comprises continuing to fill liquid into the cell and rotating the cell at a second rotational speed that is higher than the first rotational speed. The invention also discloses a cell for use in these methods which cell includes a filter for preventing solids from being carried by gas during the gas purge.

1. In a method for preparing a liquid comestible from a cell by passing liquid through a liquid comestible forming substance in the cell using centrifugal forces provided by rotating the cell about a central axis, the improvement which comprises controllably purging gas from the cell through at least one gas purge conduit as liquid fills the cell, wherein gas purging ends by closing the at least one gas purge conduit by a valve. 2. The method according to claim 1, wherein the centrifugal forces are applied to rotate the cell at a rotational speed, and which further comprises increasing the rotational speed of the cell after liquid has filled the cell. 3. The method according to claim 2, wherein the gas purge conduit is closed or the rotational speed is increased after a predetermined volume of liquid is filled in the cell or after a predetermined period of time has elapsed. 4. The method according to claim 2, wherein the gas purge conduit is closed or the rotational speed is increased after a level of liquid is detected on the top or outside of the cell. 5. The method according to claim 1, wherein the gas purge conduit is closed automatically by effect of the centrifugal forces acting on the closure of the valve. 6. In a method for preparing a liquid comestible from a cell by passing liquid from a liquid injection conduit through a liquid comestible forming substance in the cell using centrifugal forces provided by rotating the cell about a central axis, the improvement which comprises controllably purging gas from the cell through one or more controlled gas purging conduit(s) as liquid fills the cell, with the gas purging conduit(s) substantially concentrically arranged around the liquid injection conduit and the central axis of rotation of the cell, with the gas purging conduit(s) allowing the gas to move away from the cell in a direction opposite to the direction of injection of liquid into the cell. 7. The method according to claim 6, which further comprises prewetting the substance in the cell by filling liquid in the cell and rotating the cell at a first rotational speed; and then extracting the liquid comestible from the cell in an extraction phase which comprises continuing to fill liquid into the cell and rotating the cell at a second rotational speed that is higher than the first rotational speed. 8. The method according to claim 7, wherein a series of gas purging conduits are present, arranged concentrically about the injection conduit, with the conduits associated with sealing elements that are initially relaxed to close the conduits but that deform at the second rotational speed to allow gas to be purged through the conduits. 9. The method according to claim 6, wherein a single cylindrical gas purging conduit is present and surrounds the injection conduit, the gas purging conduit having a free end or inlet of that is operatively associated with a particle filter in the form of a grid, mesh or sintered block, or with the particle filter in the form of a series of slots in an upper portion of the cell subjacent the free end or inlet of the cylindrical gas purging conduit. 10. In a method for preparing a liquid comestible from a cell by passing liquid from a first liquid injection conduit through a liquid comestible forming substance in the cell using centrifugal forces provided by rotating the cell about a central axis, the improvement which comprises controllably purging gas from the cell through at least one gas purging conduit as liquid fills the cell, wherein the at least one gas purging conduit is other than the first liquid injection conduit. 11. The method according to claim 10, wherein gas is purged through a gas purging conduit concentrically arranged around the first liquid injecting conduit. 12. The method according to claim 10, wherein the centrifuged liquid is prevented from being discharged from the cell by a discharge valve until a sufficient centrifugal speed is reached. 13. In a method for preparing a liquid comestible from a cell by passing liquid through a liquid comestible forming substance in the cell using centrifugal forces, the improvement which comprises controllably purging gas from the cell as liquid fills the cell, wherein the method is conducted in a beverage production system comprising: liquid injection means for passing the liquid into the cell by injection,rotational driving means for driving the cell in rotation at least one centrifugal speed to apply the centrifugal forces to the cell,peripheral discharge means for enabling the liquid comestible to leave the cell while the cell is rotating at the centrifugal speed,gas purging means configured to controllably purge gas from the cell as the liquid fills the cell, andmeans for detecting the filling level of liquid in the cell. 14. The method according to claim 13, wherein the purging means comprises at least one gas dedicated purging conduit. 15. The method according to claim 14, wherein the gas is controllably purged by providing a valve for controlling the opening and closing of the gas purging conduit. 16. The method according to claim 13, which further comprises providing speed control means for increasing the rotational speed of the driving means to vary the beverage preparation cycle from a prewetting phase to an extraction phase. 17. In a method for preparing a liquid comestible from a cell by passing liquid through a liquid comestible forming substance in the cell using centrifugal forces, the improvement which comprises controllably purging gas from the cell as liquid fills the cell, wherein the method is conducted in a beverage production system comprising: liquid injection means for passing the liquid into the cell by injection,rotational driving means for driving the cell in rotation at least one centrifugal speed to apply the centrifugal forces to the cell,peripheral discharge means for enabling the liquid comestible to leave the cell while the cell is rotating at the centrifugal speed, andgas purging means configured to controllably purge gas from the cell as the liquid fills the cell, wherein the gas purging means comprises fluid selective sealing means that include a free interstice between the liquid injecting means and a bore of a rotary engaging base engaging on the cell. 18. The method according to claim 17, wherein the free interstice is obtained by helicoidal threading. 19. The method according to claim 17, wherein the cell comprises a cup-shaped body that contains therein a liquid comestible forming substance; and a filter for preventing solids from being carried by gas during the gas purge. 20. The method according to claim 19, wherein the filter is placed in a central portion of an internal lid inserted in the cup-shaped body of the capsule.
