Abstract: A separating apparatus for separating a suspension includes a centrifugal separator for reducing cross-contaminations in the processing of products, the centrifugal separator having a frame or a housing and a separator insert mounted rotatably with respect to the frame or housing and forming a preassembled, interchangeable unit. The separating installation has at least one container connected to at least one product-discharge line. The separating apparatus has a filling-level measuring device for determining a liquid level of the suspension within the container and/or at least one limit switch for detecting a liquid level reached within the container.

Abstract: 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 pre-assembled, 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.

Abstract: An exchangeable separator insert is designed for insertion into stator magnets of the frame of the separator and includes a housing, which is stationary during operation and which is designed in the manner of a container that is closed except for one or more openings. A rotor is disposed within the housing and is rotatable about an axis of rotation, the rotor having a drum which has one or more openings. At least two rotor magnets are at two axially spaced points of the rotor to keep floating and rotatably support the drum within the housing during operation. For transport or installation, the separator insert is provided with one or more transport securing elements, which operate according to a magnetic principle of action, so that the drum, which freely floats during operation of the separator, is immovable or substantially immovable in the housing during transport or installation.

Abstract: A separator has a frame with receiving areas for rotatably supporting the separator insert. Each receiving area having a stator device as a sub-element of a magnet bearing device, and a separator insert as a pre-assembled replaceable unit for inserting into stator units on a frame or in a housing of the separator. The separator insert has: i) a rotor rotatable about a rotational axis and which having a drum and a drum wall, and ii) at least two rotor units as sub-elements of the magnet bearing devices at two axially spaced positions of the rotor with the drum. The rotor units hold, rotatably support, and rotate the rotor together with the drum in a suspended manner within the housing during a separation mode. The separator has at least one linear drive for linearly moving at least one of the two receiving areas relative to the separation insert.

Abstract: A method for operating a separator for reducing cross-contaminations when processing products involves providing a separator insert on a frame or in a housing of the separator as a preassembled, exchangeable unit for insertion in stator units. The separator unit includes at least a rotor which is rotatable about an axis of rotation and has a drum and a drum wall, a separating means arranged in the drum, and at least one product feed line and two product discharge lines, the regions of the separator insert that come into contact with the product are partially or completely made of plastics material. A starting product to be separated is introduced into the separator. A first and a second product flow separated from the product mixture are discharged out of the separator through the two separate product discharge lines during a separation operation of the separator. The separation operation is stopped and residual liquid remaining in the drum is drained.

Abstract: A separator insert includes a housing that is stationary during operation and which is a container that is closed apart from a number of openings. A rotor is arranged within the housing and is rotatable about an axis of rotation. The separator insert includes a drum with openings. At least two rotor units for magnetic bearing units are arranged at two axially spaced apart points on the rotor with the drum, that hold the rotor in a suspended state and that can rotate the rotor.

Abstract: 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.

Abstract: A separator for the centrifugal processing of a free-flowing product includes a rotatable drum with a vertical rotation axis. The rotatable drum has a centrifuging chamber and a maximum radial diameter. An annular cover is placed onto an upper end of the drum and is configured as a part that does not rotate with the drum during operation. At least one sealing arrangement with two sealing rings is arranged between the drum and the annular cover. A leakage chamber having an outlet is formed between the two sealing rings of the at least one sealing arrangement. A splash ring, which is fastened to the drum for rotation therewith, is arranged in the leakage chamber.
