An exchangeable separation insert and a modular centrifugal separator are disclosed. The insert includes a rotatable rotor casing and a first stationary portion. The rotor casing delimits a separation space and includes frustoconical separation discs. The first stationary portion is biased in a first direction away from the rotor casing along an axial direction.

An industrial centrifuge for extracting one or more compounds from biomass includes a centrifuge basket disposed within a cylindrical vessel. The centrifuge basket includes a cylindrical sidewall comprising an upper perforated portion and a lower solid portion and a basket baseplate coupled to the sidewall between the upper perforated portion and the lower solid portion. The centrifuge includes a spindle coupled to the basket baseplate, a spindle bearing assembly, and a contact seal disposed between the spindle bearing assembly and the basket baseplate. The lower solid portion of the sidewall, the spindle, and the basket baseplate define a skirted volume. During operation of the industrial centrifuge, air trapped within the skirted volume provides an air seal between an extraction fluid in the cylindrical vessel and the contact seal, spindle bearing assembly, or both, to prevent extraction fluid from contacting the spindle bearings and causing damage thereto.

A separator includes a frame and a separator insert exchangeably disposed on the frame. The separator insert is designed to separate a flowable suspension into at least two flowable phases of different density in a centrifugal field and forms a preassembled, exchangeable unit for inserting into stator units on the frame of the separator. Mutually spaced holders having stator units of the bearing devices are formed on the frame, between which holders the housing of the separator insert is non-rotatably retained such that the rotor with the drum remains rotatable. The relative position of the holders can be changed such that the separator insert can be exchanged. The housing and the holders have corresponding interlocking elements in order to non-rotatably retain the housing at the holders.

A separator insert for a separator includes a housing that is stationary during operation and is a container that is closed apart from multiple openings. These openings include a supply opening for an in-flowing suspension in a first axial boundary wall of the housing, two outlets for flowable phases of differing densities in an outer casing of the housing, and a recirculation inlet in a second axial boundary wall of the housing. A rotor within the housing can rotate about an axis of rotation and has a drum, which has multiple openings. A separator is arranged in the drum. At least two rotor units for magnetic bearing units are arranged at two axially spaced-apart points on the rotor with the drum, with which the rotor with the drum can be held in a suspended state, can be rotationally mounted and can be made to rotate within the housing during operation.

Accelerators and conveyor bodies for a decanter centrifuge are discussed. A decanter centrifuge may have a bowl forming a sedimentation chamber with a cake discharge and a centrate discharge; a screw conveyor within the sedimentation chamber, the screw conveyor having a conveyor body and a flight, the conveyor body defining a feed chamber; and an accelerator within the feed chamber for increasing the angular velocity of a feed mixture prior to entering the sedimentation chamber, the accelerator comprising an impeller with plural vanes, the plural vanes being releasably mounted to the conveyor body and sized to pass through an axial end of the conveyor body.

Provided herein are devices and methods for sample isolation comprising a planar member configured to rotate around a bearing, and a plurality of apertures positioned at an angle to the planar member. Exemplary embodiments relate generally to the field of sample isolation, and more particularly to sample isolation using centrifugal and magnetic forces.
