Separation process and operation mode of vegetable oil sedimentation centrifuge

Feb 07, 2019

The drum of the vegetable oil decanter centrifuge is mounted on the upper end of the vertical shaft and is driven by a motor to rotate at a high speed through a transmission. The drum has a set of disc-shaped parts that are nested together. There is a small gap between the disc and the disc. The suspension is added to the drum by a feed tube located at the center of the drum. When the suspension (or emulsion) passes through the gap between the discs, the solid particles (or droplets) settle onto the disc under the action of the centrifuge. Forming sediment.

 

The sediment slides along the surface of the vegetable oil decanter centrifuge disc and is separated from the disc and accumulates in the portion of the drum having the largest diameter. The separated liquid is discharged from the liquid outlet to the drum. The function of the disc is to shorten the settlement distance of the solid particles, enlarge the settlement area of the drum, and greatly improve the production capacity of the separator due to the installation of the disc in the drum. The solids accumulated in the drum are dismantled by the drum after the separator is stopped, or are discharged from the drum by the slag discharge machine without stopping the machine.

 

The vegetable oil decanter centrifuge can perform two operations, liquid-solid separation and liquid-liquid (or liquid-liquid-solid) separation (ie, separation of the emulsion). The vegetable oil sedimentation centrifuge is used for processing and refining vegetable oil because of its compact structure, small footprint and large production capacity.
