ABSTRACT:
A centrifugal separator particulary adapted for food products removes foreign particles and objects which are denser than the main slurry. It is especially effective in removing trace amounts of metal and bone fragments and other hard foreign material from meats, emulsified batters and other food mixtures without materially changing the physical character of the input product. The separator includes a centrifuge chamber with a central impeller, with specific spatial relationships between the impeller and the nearby axially disposed inlet opening. Food batter or slurry is moved through the separator by the action of the impeller driving the slurry radially outwardly, in combination with a set of pumping vanes positioned adjacent to and communicating with the centrifuge chamber. Foreign matter denser than the main batter or slurry collects on a peripheral wall of the chamber and is not discharged, it being generally of small volume. An easily removable stationary cover over the centrifuge chamber includes an annular ledge that forms a non-contacting seal with an annular projection on the rotatable chamber body to prevent leakage of the purified slurry being pumped.
