Abstract:
An apparatus 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. The apparatus includes a liquid injection member comprising a needle for injecting liquid into the cell, a motor and shaft for centrifugally and rotationally driving the cell at at least one centrifugal speed, a peripheral discharge valve for enabling liquid extract to leave the cell after the centrifugal speed is achieved, and a gas purging conduit configured and positioned to remove gas from the cell as liquid fills the cell.
