A separator arrangement includes a separator having a drum with a vertical rotation axis. The drum is placed on a rotatable drive spindle and is surrounded by a shroud. A separating wall separates the separator arrangement into a sanitary area that includes the drum and the shroud and a drive area that includes the drive device. The separator and the drive device are decoupled as a unit, in terms of vibration, by at least one of the separating wall and a foundation attachment. The drive device includes a motor, a coupling, at least one bearing device, and a flange section around the drive spindle underneath a drive cover, and a sealing device. A membrane arrangement is formed in a region of the drive cover and, for vibration purposes, decouples the drive cover from the machine frame in a region around the drive spindle.

Spacers are roller welded or laser welded to a disk, welding the interstices between the spacers and the disk liquid tight. Nothing can accordingly accumulate in the interstices to contaminate the centrifugate.

Centrifuge-drum disk

A centrifuge drum for concentrating suspended solids, which are conveyed through channels out of an outer solids space in the drum and into a radially inner peeling chamber, whence they are diverted by a peeler and by an associated concentrate line. A separated clear phase is continuously extracted from the interior of the drum by another peeler and by an associated clear-phase line. The object is to prevent the concentrated solids from heating up undesirably even when their volume is small. There is an opening-and-closing communicating line between the concentrate line and the clear-phase line and an opening-and-closing recirculation line extending into the first peeling chamber from the clear-phase line. The communicating line and the recirculation line are closed to divert the solids and opened to discontinue the diversion.

Centrifuge drum for concentrating suspended solids

The peeling chamber in a head of a centrifuge has an upstream barrier chamber that seals it off from the atmosphere. A barrier disk secured to a peeler extends into the barrier chamber. Compressed gas is supplied to between barrier disk and peeler through a channel to prevent gas from escaping from the solvent. Another channel supplies liquid to the barrier chamber. Solvent from the periphery is supplied to the barrier chamber through a channel and simultaneously by the peeler through the barrier-liquid channel. An area of separation becomes established between the two liquids in the barrier chamber. If any solid particles enter the barrier chamber as the result of gas leaving the solvent, they will dissolve again in the solvent in the periphery of the barrier chamber and will be prevented from making the chamber malfunction.

Centrifuge with a vertical axis of rotation

A throughput centrifuge for the industrial production of proteins from human blood plasma, with a cylindrical centrifuge drum provided with several concentric chambers that communicate at the bottom and with the blood plasma or similar material being supplied to the central zone and a liquid phase continuously extracted from the outer zone. The drum accordingly accommodates plastic containers constituting concentric annular or annular-segmental chambers that communicate through at least one channel at the bottom, wherein the container or containers toward the axis that the drum rotates around have an inlet connection and the container or containers in the outer zone of the drum have an outlet channel at the top, and wherein the outer surfaces of the containers, of the communicating channel or channels, of the outlet channel or channels, and of the inlet connection or connections rest against the inner surfaces of the drum and against structures that can be inserted into and removed from the drum.

Throughput centrifuge for industrial production of proteins from human

A centrifuge, preferably a sterile laboratory centrifuge, with an intake channel for the material being centrifuged, a runoff channel for the clear phase, and a drum with a centrifuging space comprising a separation space equipped with a package of disks and a solids. The centrifuge has an initial operation that comprises introducing material to be centrifuged into the separation space and separating the solids from the clear phase, which is followed by another operation that comprises discontinuing the intake of material to be centrifuged and introducing rinse into the drum through the clear-phase runoff channel. A channel that is employed during the initial operation to supply the material to be centrifuged has two sections, between which is accommodated a valve chamber and a valve body, wherein a channel for diverting the solids extends from the periphery of the solids space to the valve chamber, and wherein the valve body is reversed to initiate the second operation, separating the second channel section, which leads from the valve chamber to the separation space, from the first channel section, connecting the solids-diversion channel to the first channel section, and allowing the solids to be extracted through the first channel section.

Sterile laboratory centrifuge

A method for producing citrus juices with low final percentages of pulp. A centrifuge is used, with the space in the drum that receives the heavier phase, the phase with a high concentration of pulp, discontinusously emptied of at least some of the pulp through slide-activated extraction openings in the jacket of the drum. The light phase, the clarified juice, is continuously extracted. To ensure that the juice will be clarified considerably more effectively in the centrifuge at low energy and equipment costs, with the throughput increased incrementally, juice with a high concentration of pulp is continuously extracted from the centrifuge through channels or through an annular space that is demarcated on the inside by a large separating disk and that has an inflow opening at the largest inside diameter of the drum.

A self-emptying centrifuge drum has an intake for the centrifugate, a peeling chamber that accommodates a peeling disk for diverting the clarified liquid, and an automatic device that senses the level of solids in the separating space of the drum. The sensing device consists of channels extending from the separating space to another peeling chamber with another peeling disk. The outflow channel from the second peeling disk communicates with a measuring instrument that operates in conjunction with controls that introduce the extracted solids into the drum. Peeling channels are provided in the second peeling disk, extending out from its circumference and opening tangentially into an annular space that does not have any ribs and that extends radially inside the disk to detect the level of solids in the separating space even when centrifugates that do not block the channels sufficiently are being clarified.

Self-emptying centrifuge drum

A centrifuge drum has a chamber that can accommodate fluid formed by a concentric component inserted into the drum. The concentric component has a sealing ring accommodated in an annular groove at its outer diameter. The base of the annular groove can be supplied with control medium through a channel and emptied again through an outlet device. When the channel is full, the sealing ring is forced against a cylindrical surface and seals off an annular gap. When the channel is empty, the pressure of the fluid in the chamber forces the sealing ring in, releasing the annular gap for the chamber to empty through. In addition to acting as a seal, the sealing ring also acts as a valve, and allows a very simple design for all types of centrifuge-drum chambers that must be filled and emptied again during operation.

Centrifuge drum

The centrifuge has a self-emptying drum. There are expulsion apertures in the bottom of the drum. The apertures lead from a solids space and can be closed off with a piston slide. A closure chamber that can be charged with closure liquid is associated with the piston slide. The closure chamber communicates with a chamber through a bleed channel in the form of an annular gap and through a valve gap. The annular gap has an extensive cross-section that promotes rapid flow and accordingly especially accelerates bleeding the closure liquid out of the closure chamber into the other chamber. This makes it possible to increase the stroke of the piston slide at a prescribed extraction volume when the drum empties.

Centrifuge with a self-emptying drum

A centrifuge with a self-emptying drum is provided with expulsion openings in its jacket that lead from the solids space and that can be closed off by a piston slide. The piston slide is associated with a closure chamber, which can be supplied with a closure fluid and which has outlet channels around it that can be closed off by a valve body and that open into a blocking chamber. The blocking chamber can accommodate part of the closure fluid taken in by the closure chamber. The valve body and the piston slide are moved into the opening position for partial emptying. The valve body remains in the open position during partial emptying. The outlet channels are blocked by closure fluid taken in by the blocking chamber. This blocking fluid initiates the closing motion of the piston slide while closure fluid continues to be supplied to the closure chamber.

Centrifuge with self-emptying drum

A centrifuge with a self-emptying drum has ejection openings in its jacket that lead out of a solids space and can be blocked off with a piston valve. It has a closure compartment that can be charged with closure fluid and is associated with the piston valve. Part of the closure compartment is divided into an upper and a lower division by a disk. Outflow channels lead out of the drum from the lower division of the closure compartment. The disk can be displaced axially. When it is in its lower position, it hermetically seals off the lower division of the closure compartment from the rest of the compartment. When it is in its upper position, into which it can be displaced hydraulically, the disk allows the lower division to communicate with the rest of the closure compartment so that closure fluid flows out of the compartment through its lower division and through outflow channels. Once a predetermined hydrostatic pressure has been attained in the lower division, the disk automatically returns to its lower position, terminating the outflow of closure fluid.
