Abstract
A continuously operating centrifuge for producing a high purity sugar or sugar syrup, has an acceleration bell or cone which acts as a preliminary separator, and a centrifugal basket, the lower portion of which acts as a washing stage. A damming ring is spaced from the upper edge of the basket to form with said upper edge a sugar exit gap. A discharge ring is arranged to cooperate with the damming ring. The discharge ring rotates with the basket, but about an axis extending at an angle relative to the rotational axis of the basket, whereby the actual sugar exit is confined to a predetermined zone along said sugar exit gap. A flow channel cooperates with said zone to receive the sugar without damage to the sugar crystals.
Claims13
A continuously operating sugar centrifuge comprising a housing, drive shaft means supported in said housing for rotation about a vertical axis, and having an upper free end, acceleration cup means rigidly secured to said free shaft end, centrifugal basket means having a bottom and an upper rim also rigidly secured to said free shaft end, acceleration cone means secured for rotation and cooperation with said basket means and with said cup means, massecuite filling pipe means centrally reaching through said housing into said cup means, said acceleration cone means comprising preliminary separation means, green flow-off discharge means arranged for cooperation with said preliminary separation means, washing means located in said centrifugal basket near said bottom thereof, damming ring means secured in said housing in spaced relationship to said upper rim of said centrifugal basket to define a discharge gap between said upper rim and said damming ring means, discharge ring means supported in said housing for rotation about an axis extending at an angle relative to said vertical axis, said discharge ring means comprising downwardly extending collar means radially outwardly of said upper rim of said centrifugal basket means whereby a sugar exit area is confined to a definite zone along said upper rim of said centrifugal basket, and flow channel means arranged to receive sugar emerging from said exit area.
