Abstract: In a self-cleaning liquid-solids centrifugal separator having a drum wherein a piston is displaced periodically to expose a sludge discharge orifice through which sludge is discharged without stopping rotation of the drum, a second piston is provided. The second piston defines a chamber with the first piston which is filled with a control fluid. The second piston is displaced as the weight of sludge increases and when it moves a predetermined extent the flow of control fluid causes said first piston to move and expose said discharge opening. Displacement of the second piston can also set in operation a control mechanism which, either during each cycle or after a predetermined number of cycles, drains control fluid from the system and permits complete discharging of sludge from the drum even after the weight of sludge on the second piston is below the level at which it would otherwise cause the first piston to return to the position wherein the discharge orifice is closed.

Abstract: A centrifugal separator constructed for performing full desludgings as well as partial desludgings during separation. One end member of the separating chamber is a piston valve movable axially to open and close sludge discharge openings disposed at the outer periphery of the drum. The axially outward disposed side of the piston valve is in sliding sealing engagemenet with confronting drum portion at radially spaced intervals so that a radial succession of divisions of the closing chamber is provided which can be filled up in a known manner with control fluid and selectively emptied for reducing the force acting on the piston valve and thereby performing a full desludging or a partial desludging.

Abstract: STARCHIFEROUS MATERIAL SUCH AS POTATOES ARE PULPED; STARCHIFEROUS SOLIDS ARE SEPARATED AND PASSED THROUGH A WASHING SECTION IN WHICH STARCH IS EXTRACTED WITH A LIQUID IN A PLURALITY OF CONTACTING STAGES; THE LIQUID IS PASSED THROUGH THE WASHING SECTION COUNTERCURRENTLY WITH RESPECT TO THE SOLIDS; AND LIQUID FROM THE WASHING SECTION CONTAINING EXTRACTED STARCH IS PASSED TO REFINING SECTION WHEREIN THE STARCH CONTENT THEREOF IS ENHANCED. IN AT LEAST SOME OF THE CONTACTING STAGES, THE LIQUID CONTAINING EXTRACTED STARCH, SEPARATED FROM THE SOLIDS, BEFORE TRANSFER TO THE NEXT PRECEDING CONTACTING STAGE IS CENTRIFUGED TO SEPARATE A CONCENTRATED STARCH MILK, AND THAT MILK IS FED TO THE REFINING SECTION FROM THE WASHING SECTION. IN THIS WAY THE WATER LOAD IN THE REFINING SECTION IS REDUCED.

Abstract: Self dumping centrifugal separator having a paring chamber and disk for removal of clarified liquid, and, for dumping, a main valve at the periphery of the drum for periodic ejection of solids and a secondary valve for removal of liquid from the separating zone to reduce the discharge of liquid through the main valve during dumping. Means, such as springs, urge the secondary valve into a normally closed position. A control chamber is provided for receiving liquid to urge the secondary valve to the open position and a passageway communicates the control chamber with an annular groove separated by a weir from the paring chamber, the weir being of greater inside diameter than the inside diameter of the paring chamber cover. Upon interruption of flow of clarified liquid from the paring disk, during initiation of dumping, liquid in the paring chamber overflows the weir and flows into the annular groove, through said passageway to the control chamber and forces the secondary valve to the open position for discharge of liquid from the separating zone.

Abstract: Self-dumping centrifugal separator having a main valve at the periphery of the drum for periodic dumping of solids and a secondary valve for removal of liquid from the separating zone to reduce the discharge of liquid through the main valve during dumping. Means, such as springs, urge the secondary valve into a normally closed position. A control chamber is provided for receiving liquid to urge the secondary valve to the open position and a passageway communicates the control chamber with an annular groove in the drum adjacent the drum axis. The drum includes means for sensing build-up of solids in the solids collecting chamber, including a sensing liquid receiving chamber, having a lower lip and an upper lip, in the drum formed as an annular groove about the drum axis, means for delivering sensing fluid to that chamber and means for delivery of sensing fluid from the chamber to the inner boundary of the solids collecting chamber, and a pulse sensing means projecting into that chamber. The control chamber and the sensing liquid receiving chamber are separated by one of the lips of the sensing liquid receiving chamber. The separating lip is of greater inside diameter than the other lip of the sensing liquid receiving chamber, and the pulse responsive means projects into the sensing liquid receiving chamber to a point radially outward of the inside diameter of the separating lip. Upon build up of the liquid level in the sensing liquid receiving chamber, the pulse responsive means is first contacted and then the liquid overflows into the control liquid receiving chamber. Thereby, the control chamber is filled with liquid which forces the control valve to the open position for discharge of liquid from the separating chamber.
