After planting and harvesting of groundnuts, well selected grains are pressed using a screw oil pressing machine. During pressing we get the crude peanut oil and the peanut cake. Crude peanut oil is then filtered, refined and bottled in plastic bottles to distributed to supermarkets for sale. The peanut cake can be mixed with other components, ground into powder for the feeding of poultry. Or pelletized using a pelletizing machine to produce animal feed.
During filtration of the peanuts we obtain sludge which is also a very good fertilizer for the farms. In this oil production there are no waste. Every product is useful.
