Abstract
A method for influencing the pulp content of a fruit or citrus juice. The method steps include: continuously purifying the juice of a pulp phase in a centrifugal field of a separator, the pulp being discharged from a drum of the separator through a pulp discharge line; measuring a density of the discharged pulp phase by a density flow-through measuring device; and, controlling a controllable device in accordance with a density measurement by the density flow-through measuring device thereby influencing the density of the pulp phase.
Claims17
A method for influencing the pulp content of a fruit or citrus juice so that a sufficient amount of pulp is accumulated to flow over a separation plate of a separator, the method steps comprising:
- providing a separator having a separator plate;
- continuously separating a juice of a pulp phase in a centrifugal field of the separator, the juice including a pulp content having been fed into the separator and the pulp phase being discharged from a drum of the separator through a pulp discharge line;
- measuring a density of the discharged pulp phase by a density flow-through measuring device;
- controlling a controllable device in accordance with a density measurement by the density flow-through measuring device thereby influencing the density of the pulp phase and providing a sufficient amount of pulp to flow over the separator plate;
- and
- controlling a first peeling disk of the separator, the first peeling disk configured to control the discharge of the pulp phase from the separator.
A method for providing a sufficient amount of pulp accumulation in a centrifuge solid matter collection chamber such that the pulp begins to flow over a separation plate in the centrifuge, the method steps, comprising:
- providing a centrifuge having a drum, a separator plate, a solids collection chamber, and a first peeling disk;
- feeding a juice having a pulp content into the centrifuge via a feed line;
- initially starting up the centrifuge and separating the juice having the pulp content into at least a pulp phase, the pulp phase being discharged from the separator via the first peeling disk and a pulp discharge line, and the pulp phase being initially substantially clarified juice;
- measuring a density of the discharged pulp phase by a density flow-through measuring device;
- controlling a controllable device based upon the density measurement of the pulp phase and recirculating at least a portion of the discharged pulp phase via a recirculating line back to the feed line until a sufficient amount of pulp has accumulated in the solids collection chamber such that the pulp starts to flow over the separator plate.
