The present disclosure relates to a centrifugal separator (1), which comprises a rotatable drum (5) having a wall (50), an annular chamber (7) defined along the longitudinal axis (49) of the rotatable drum (5) in a portion adjoining to the wall (50), wherein a mixture of substances in the liquid phase and in the solid phase is movable longitudinally through the annular chamber (7), and a discharging station (13) for discharging the solid phase. The discharging station (13) comprises a vibrating unit (300) for agitating the solid phase. The vibrating unit (300) comprises a half-drum (302) and a vibrating device (304) adapted to vibrate the half-drum (302).

Pusher centrifuges having screen drums rotatable about axes of rotation are used for separating a mixture into solid cake and into liquid phase. Pusher centrifuges may further have pusher bases arranged in the screen drums and arranged to be movable to and fro alternately in a first pushing direction and a second pushing direction along the axis of rotation that are used in order for the solid cake to be alternately displaced along the axis of rotation. The mixture is introduced into a first empty space or into a second empty space using a feed device. The first empty space is established on a displacement of the solid cake by the pusher base in the first pushing direction and the second empty space is established on a displacement of the solid cake by the pusher base in the pushing direction opposite to the first pushing direction.

A supercentrifuge with a non-intrusive device for the extraction of solids, the supercentrifuge comprising a chamber or rotor for the clarification of liquids and a piston located within the chamber passing through it in order to discharge the solids, the piston being driven in its outward travel along the chamber by the injection of a pressurised fluid which pushes the piston, in which the supercentrifuge has a pneumatic pumping system for the generation of vacuum to bring about return movement of the piston along the chamber.

A separator extracting dry chopped food waste material from wet chopped food waste material fed in fluid state includes an outer container for an internal centrifuge having a rotating cylinder with perforated walls, which contains a rotating screw that advances the wet chopped food material and separates the liquid portion therefrom; an inlet opening, which receives the wet chopped food material to be introduced into the rotating cylinder through a hollow duct inside the screw feeder, causing its upward movement and advancement; and an outlet opening, which evacuates the chopped material without the liquid portion. The outer container includes upper and lower half-shells that are monolithic and integral sanitation elements of the separator and a centering and sealing element at a coupling area, a flow-regulation valve being positioned at a lower opening to evacuate the separated liquid from the outer container.

A centrifugal dryer includes a housing and a basket positioned within the housing. The basket defines an opening formed laterally there through. The basket rotates around a central longitudinal axis through the housing. An annulus is formed between the basket and the housing. A cleaning device is positioned within the annulus, and the cleaning device introduces a liquid into the annulus. A scraping device is positioned within the annulus, and the scraping device rotates to remove cuttings from at least one surface.

A decanter centrifuge that carries out solid-liquid separation by centrifugal force on an object to be processed that is fed into a rotating bowl and designed from a solid and a saturated solution wherein that solid is dissolved, and discharges solid phase components from a solid discharge opening and discharges liquid phase components from a solvent discharge opening thereof by rotationally operating a screw conveyor disposed within the rotating bowl, the decanter centrifuge being provided with a dilution solvent supply unit for supplying, during centrifuging of the object to be processed, dilution solvent that reduces the concentration of the saturated solution to a discharge path, which is a discharge path for saturated solution moving within the rotating bowl, and which is designed closer to the solvent discharge opening side-than a chamber for supplying the object to be processed.

A centrifugal separator is provided with a base and a substantially vertical spindle upstanding from the base. A rotary vessel is mounted on the spindle. A housing is connected to the base and encloses the rotary vessel. A liquid supply duct supplies a liquid to be filtered to the rotary vessel. The rotary vessel has an open top and an upper edge at the open top. The rotary vessel is provided with a filter material and has a weir arranged at the upper edge, wherein the filter material extends upwardly to the weir. The housing has a passageway adjacent to the weir and the passage way communicates with the weir to enable discharge of waste material that is contained in the liquid to be filtered and does not pass through the filter material during supply of liquid to be filtered to the rotary vessel and rotation of the rotary vessel.
