Patent ID: 8512784

Claim:
A beverage production device for preparing a liquid comestible from a portioned food substance contained in a capsule or cell, comprising: a centrifugal unit for receiving the capsule or cell, driving means connected to the centrifugal unit for providing a rotational motion of the capsule or cell in the centrifugal unit, liquid supply means being connected to the centrifugal unit to supply liquid in the capsule or cell, means for measuring (1) the flow rate of the liquid that is to be supplied to the capsule or cell, or (2) the pressure of the liquid in the capsule or cell, and a control unit operatively associated with the measuring means for controlling one of the flow rate or pressure to match a flow rate reference or a pressure reference, respectively, in a control loop by automatically adjusting the rotational speed of the driving means during an extraction phase of the beverage production depending on the measured flow rate or the measured pressure.
