Abstract: A separator includes a rotatable drum having a vertical rotational axis, a disk stack arranged in the drum, an inner gripper and an outer gripper that do not rotate with the drum are configured to discharge mutually-separated liquid phases. A discharge line is assigned to each gripper and is arranged in an associated gripper chamber of the drum. The inner gripper includes an inner gripper shaft and the outer gripper includes an outer gripper shaft both of which shafts protrude axially from the drum. Each associated gripper chamber, with its associated gripper, revolves on different radii with respect to the rotational axis such that a chamber is formed radially between an outer circumference of the inner gripper shaft and an inner circumference of the outer gripper shaft. A fluid is insertable into the chamber through a channel, which fluid is pressable from the chamber into the gripper chambers.

Abstract: A rotatable separator drum includes a vertical rotating axis of rotation and at least one flow channel having an inlet opening and an outlet opening. Also included is at least one retaining dam arranged in the at least one flow channel in a region between the inlet opening and the outlet opening. The at least one retaining dam is configured to allow an overflow of liquid over the at least one dam and to provide for an accumulation of solids in front of the at least one dam. The at least one dam includes at least one rib arranged in a transitional region between opposing wall sections and a distributor base cover and the at least one rib includes portions having differing heights.

Abstract: A method for influencing the pulp content of a fruit or citrus juice. The method steps include: continuously purifying the juice of a pulp phase in a centrifugal field of a separator, the pulp being discharged from a drum of the separator through a pulp discharge line; measuring a density of the discharged pulp phase by a density flow-through measuring device; and, controlling a controllable device in accordance with a density measurement by the density flow-through measuring device thereby influencing the density of the pulp phase.

Abstract: A three-phase solid bowl screw centrifuge includes a rotatable drum, a screw arranged in the drum, a solid material discharge located at the fist axial end of the drum, and two liquid outlets are located at a second axial end of the drum. A first of the liquid is for a lighter liquid phase and a second of the liquid outlets is for a heavier liquid phase. One of the liquid outlets includes a skimmer disk arranged in a skimmer chamber and the other of the liquid outlets is formed as an overflow. Two regulating disks are located in the front of the skimmer disk. The regulating disks extend radially from an outside of the drum toward an inside of the drum. A siphon disk extends between the regulating disks and into the skimmer chamber from a interior circumference of the skimmer chamber to an exterior circumference of the skimmer chamber. An annular chamber is formed during an operation and is located between the siphon disk and the skimmer disk.

Abstract: A filtration system for clarifying a cloudy beverage from at least one tank in which dregs have formed, the clarifying occurring through a cross-flow filtration. The filtration system includes: a first filtration module having a first filtration element, the first filtration element including a first channel having a first diameter; and, a second filtration circuit located in parallel to the first filtration circuit, the second filtration circuit including a second filtration module having a second filtration element, the second filtration element including a second channel having a second diameter, the second diameter being larger than the first diameter. A method for filtering a cloudy beverage from at least one tank in which dregs have formed, the method using the just-described filtration system.

Abstract: A solid-bowl centrifuge that includes a drum rotatable about a horizontal axis of rotation and a screw arranged in the drum. Also included are a continuous solids discharge located at a first end of the drum and a continuous liquid discharge located at a second, opposite end of the drum. Further included is at least one discontinuously acting outlet opening including a closure device.

Abstract: A solid-bowl screw centrifuge includes a rotatable drum having a horizontal axis of rotation, which drum surrounds a centrifuging space. Further included is a screw which is arranged within the drum, the screw being rotatable at a different speed relative to the drum. Further included is at least one liquid discharge sealed from its surroundings and at least one solid discharge in a tapering region of the drum. Also included is an immersion disk on the screw which disk lies between a liquid feed and the solid discharge and divides the centrifuging space into a discharge space between the immersion disk and the solid discharge, and a separation space between the immersion disk and the liquid discharge. The centrifuge includes a device for charging the separation space with a gas. A process for operating for the solid-bowl centrifuge is also disclosed.

Abstract: A method for clarifying a wine sediment. The method steps include providing a solid-wall worm centrifuge, clarifying the wine sediment in the centrifuge by forming a solid phase and a liquid phase, and fining the sediment by adding a fining agent at one or both of before and during the centrifugal clarification.

Abstract: A method for producing fresh milk having a longer shelf life. The method steps include: providing raw milk; and performing an at least two-step centrifugal germ removal process of the raw milk before a standardization process of the raw milk is carried out. A method may also include performing a first step of a two-step centrifugal germ removal process before a skimming process separating skimmed milk is carried out and performing a second step of the two-step centrifugal germ removal process during the carrying out of the skimming process separating skimmed milk.

Abstract: A separator in which a product such as milk is to be processed, the separator includes: a centrifugal drum; an admission tube; a distributor including an admission chamber located downstream of the admission tube and distribution channels leading into a centrifugal chamber of the centrifugal drum. A rib body is located in the admission chamber and the rib body provides an outlet to the distributor channels. The rib body includes a plurality of ribs and a base section connecting the plurality of ribs along a periphery of the base section.

Abstract: A filtration method for a filtration device, the filtration device including a process tank, at least one feed line feeding a medium to be processed into the process tank, and at least one filtration arrangement arranged in the process tank. The process tank includes at least one drain and is configured such that filtration of the medium is accomplished such that a retentate remains in the process tank until the retentate is released after completion of the filtration. The filtration method includes the steps of: filling the process tank with the medium to be filtered and producing one of a predefined transmembrane pressure and constant permeate flow at the at least one filtration arrangement; and filtering the medium in the process tank via the at least one filtration arrangement until a predefined limit value for a mass fraction of solid material is reached.
