Abstract: A continuously operable sugar centrifugal for mixing and curing sugar massecuites includes an intermediate mixing device between inner and outer centrifugal baskets. The mixing device is formed by a ring housing with an impact zone, retaining zone, and inclined baffles to impart turbulence and transform the kinetic energy of sugar received from the inner basket into the work of mechanical mixing. Mixing liquid is introduced into the received sugar and the mixture eventually passes over the lower edge of the mixing device into the outer basket for final separation and curing. The mixing device is stationary relative to the inner basket or rotates at a slower speed and may assume a variety of advantageous geometries.

Abstract: A continuously operable sugar centrifuge separates sugar massecuites into syrup portions of differing quality and crystalline sugar. The centrifugal screening basket is mounted for rotation within a housing divided into a plurality of different compartments for receiving syrup portions of differing quality from the screening basket. The housing also includes a first common collecting chamber for green syrup and a second common collecting chamber for high green syrup. Adjustable valves are provided between at least some of the compartments and the collecting chambers for alternatively connecting a compartment to either the first or second collecting chamber for separate discharge of syrup according to the quality of syrup received in the compartment. Mixing of syrup portions of differing quality is prevented by sealing elements even though the transition zone from green syrup to high green syrup shifts up or down along the basket wall.
