Groundnut Oil Mill Plant Process

Groundnut oil processing involves several processes including peanut shell removing, cooking, pressing, filtration and refining.

Groundnut Oil Mill Plant Process Flowchart

Bucket Elevator

Bucket elevator is a conveying systems to transport large amount of peanuts vertically with its central chain, Goyum also offers efficient and proven solutions for the highest conveying capabilities.

Screw Conveyor

Groundnut are delivered into the hopper with the help of screw conveyor. It has a special anti-dust design to protect the groundnuts. The shaft of the conveyor is rotated vice versa inside the trough.


The steam in the boiler is produce by burning any type of waste such as husks, wood or other agricultural waste. The steam is let out through a pipeline which is directly connected to the kettles.

Groundnut Decorticator

It removes the husk (shell) from the groundnuts. The decorticator has rigid knives, as well as synchronized feeding options with a vibratory separator fitted underneath for efficient performance

Groundnut Cleaner

Seed Cleaner are used to remove husk, sand, metals and any other foreign materials.


The steam is required for cooking and conditioning, the peanuts by adjusting their moisture content and temperature (90ºc- 125ºc), then the pressed by oil extraction machine.

Groundnut Extraction

The cleaned groundnuts are put in the kettle of the oil press machine to squeeze out oil from it. The peanuts containing 40 – 45% oil content. To extract the oil from peanuts required double pressing. In the first pressing 25 % – 27% oil will be recovered and the oilcake goes for second pressing where 8 – 10 % oil will be recovered. The Remaining oil, 8 – 9% oil still present in the oil cake which will be used as animal feed.

Oil Filtration

Crude peanut oil obtained by pressing and it will be stored in a oil tank and then the pump will be pumped through the filter press. Filter press has fine-mesh clothes which removes the foots from the crude groundnuts oil. Filter peanut oil can be directly sold in the market. But, for better sales, it can be filled in bottles.
