Abstract
An apparatus and method for providing reduced crystal damage in a sugar centrifugal includes provisions for avoiding scratching and other crystal damage by eliminating asperities and sharp edges at the transition between the screening zone and the discharge zone of a centrifugal basket. In addition, the distance on an upper shroud ring across which high velocity crystals slide is minimized to reduce the likelihood of scratching crystals on the surface of the shroud ring. Finally, the tangential velocity at which crystals are released from the centrifugal basket is minimized to reduce impact damage to the crystals.
