Clarification station
Press cake (fibre and nuts) leaves the screw press to the depericarper and kernel line. Pressed liquor is screened, then goes to a three-phase decanter or to CST. Oil from the light phase goes to the vacuum dryer. Palm kernel oil is pressed in the kernel plant after nut cracking.
Models, wear protection and mill quotation are on the palm oil decanter page.
Mill clarification workflow
- Reception and sterilization: FFB are received and steam-sterilized. Fruit is threshed from the bunch; empty fruit bunch leaves the thresher.
- Digestion and pressing: Fruit is digested and pressed. Pressed liquor carries crude palm oil, water and fine solids. Press cake (fibre and nuts) leaves on the cake side.
- Screening: Coarse fibre is screened from pressed liquor before the three-phase decanter or CST. Liquor to the bowl is commonly 90–95°C.
- Clarification: On whole crude oil after the screen, the three-phase bowl discharges oil, water and cake. Mills that keep CST put a second three-phase bowl on CST underflow sludge.
- Oil finishing: The oil phase goes to the vacuum dryer.
Bowl models and mill quotation are on the palm oil decanter page.
