Abstract:
Process for operating a centrifuging unit, which includes a centrifuging container for separating the components of a liquid containing components with different specific weights, with the centrifuging container containing a separation chamber, an inlet for the liquid to the separation chamber, and an outlet for a separated component from the separation chamber, with the inlet and outlet extending through a revolving passage at the upper end of the container, with the inlet being connected to a feed channel which empties in a defined area of the container into the separation chamber, and with a pump device to fill and/or empty the centrifuging container, and the liquid to be centrifuged being supplied via the inlet, said process comprising the steps of reversing the direction of flow between the inlet and the outlet, after separation of a desired quantify of a component of the liquid, while rotation of the centrifuging container continues at full rpm, so that at least one of the separated components is drawn off via the feed channel and the inlet from the separation chamber; and thereafter reversing the direction of flow again, so that, via the inlet, liquids to be separated are again supplied to the separation chamber; and, during drawing off of the separated components via the inlet, supplying compensating liquid to the separation chamber via the outlet.
