Crude palm kernel oil process line includes polishing, crushing and pressing.
Polishing: Separating nuts and fiber by wind drying system. Pressed cake broken by breaking screw conveyor and then transported into the fiber separation air net and fiber polishing roller for fiber separating. The separated fiber material is sent to the boiler room as fuel; the separated stone is transported to stone warehouse by pneumatic conveying system for temporary storage.
Crushing: Crushing nuts to get kernels and shells. The nut is divided into two or more petal by corrugated crusher, kernel is released. The broken mixture enters into broken mixture separation system; separation system adopts two stage separation and water separation. After separation, shell is sent to the warehouse for temporary storage, as boiler room fuel when necessary.
Pressing: Pressing kernels to get crude palm kernel oil with palm kernel expeller machine as below.
