There is disclosed method and apparatus for cleaning roots, tubers, bulbs, and the like, for example, sugar beets, chicory, Jerusalem artichokes, dahlia, potato, and onions (hereinafter "articles"). In the apparatus, spaced horizontal rollers have helices on their cylindrical surfaces which scroll the articles laterally to the ends of the rollers where they are deposited on a slide that removes them from the cleaner, or, optionally, returns the articles to the cleaner at strategically located lower positions for stalk removal and/or leaf stripping, or for other desired cleaning. The first sets of rollers are designed to separate small chips, small stones and loose soil from the articles. The next sets of rollers are designed to remove adhering soil and/or mud, weeds, and larger stones. Strategic placement sizing, rotational speed, and direction of rotation of the helices on the rollers are instrumental in removing leaves, stalks, weeds, breaking up dirt clods and mud balls, and cleaning of the articles.

A vertical processing vessel includes an upper feed zone, an intermediate treatment zone and a lower removal zone, with the treatment zone including an improved system for distributing treating fluids uniformly across the cross-section of the vessel. The system provides for mutually perpendicular fluid distributing tubes which, in the preferred embodiment, has one set of tubes that extend completely across the vessel and a second set of perpendicular tubes that merely penetrate the wall of the vessel to deliver treating fluids along the perimeter of the vessel. The degree to which the delivery tubes in the second set penetrate the vessel is determined by the size of the vessel so that optimal conditions are attained for the delivery of the treating fluids.

The present invention relates to an improved method and system for properly and uniformly distributing fluids in upright vessels commonly called vertical shaft kilns or retorts. The distributors disclosed have a unique shape to facilitate movement of particulate matter passing by them and in addition have orifices which are recessed to keep each orifice free of solids with varying sized orifices as needed to provide the flow distribution uniformly across the lateral extent of the retort. Further the distributors are supported at each end by and protrude through nozzles built into the vessel shell to supply connection for external piping. The supports are so formed as to provide for thermal expansion through fluid-tight closures during high temperature operation.

A removal grate for a vertical shaft processor includes a distributor plate adapted to receive processed materials and an eccentric distributor wheel for breaking up the processed material and uniformly distributing it across the distributor plate for removal from the processor.

An annular compartment is disposed below the mixing ring of a rotating-basket, massecuite-separating centrifuge, to receive the magma therein. Eductors arrayed in the compartment receive hot water, and ingest magma, to eject the mix therethrough and to centrifuge the mix, while melting the sugar crystals in the magma. The melted crystals, now high brix sugar liquid, is overflowed into a companion compartment; from thence the liquid is passed over a weir, into a sub-compartment, for subsequent discharge.

An apparatus and method for reducing sugar, crystal impact damage and lump formation in a centrifugal provides a resilient barrier ring which absorbs most of the impact energy of the crystals and which deflects the crystals so they are not struck by trailing high speed crystals. An air flow causes vibration of the barrier ring to prevent crystal sticking which could lead to lump formation. This air flow also reduces moisture content in the sugar housing to further reduce lump formation.
