Used GEA Westfalia Disc Stack Centrifuge RSE110-01-776
RSE110-01-776 Disc Centrifuge Applications
Continuous degumming, neutralizing, dewaxing, and washing of fatty oils, such as various vegetable oils, lard, tallow, and fish oil.
This separator has been designed for use in the edible oil industry. The product is fed into the bowl through a closed-line system with hydrohermetic feed. The light liquid phase (clean oil) is discharged foamfree under pressure by a centripetal pump. The heavy liquid phase (soapstock or gums) is discharged by another centripetal pump. The separated solids are collected in the solids holding space and are ejected at preset intervals through ports. Partial and total ejections are possible. The self-cleaning bowl makes the machine suitable for fully automatic cleaning-in-place (CIP).

Operating principles of the Disc Separator RSE110-01-776
This disc separator RSE110-01-776 with double centripetal pump is used for the separation of mixtures composed of a liquid (oil) and pasty substances (soapstock or gums), with simultaneous removal of the solids contained in the mixture.
The solids accumulate in the sediment space G of the bowl from where they are ejected automatically, at pre-determined intervals, through ports in the bowl bottom. During partial de-sludging only part of the solid matter is ejected whereas during complete de-sludging the whole bowl contents is ejected abruptly.
B Discharge, heavy component
C Discharge, light component
D Upper centripetal pump, heavy component
I Lower centripetal pump, light component
F Disc stack
G Sediment space
H Sediment ejection port
The centripetal pump discharges the separated components of the process liquid. In the centripetal purnp the rolational energy of the process liquid in the bowl of RSE110-01-776 is converted into pressure which conveys the components as follows:
-The light component (oil) is discharged by the lower centripetal pump E at a pressure of 3 bar maximum.
-The heavy component (soapstock or a similar pasty substance or wash water or Iiquid soap) is discharged from the bowl under pressure by the upper centripetal pump D. It flows off by gravity through the lower discharge.
– The solids component is periodically discharged through solids ejection ports H.
