Oil Expellers - Extract Oil From Oilseeds With Ease

The process of oil extraction has been existent from very early times. In those days, the seeds were merely cleaned and grinded with the use of grinders or stone mills. With the advancement of science and technology, the use of machines like Screw Presses or Oil Expellers were started for expelling or extracting oil from oil seeds and nuts. Oil Expellers play a very vital role in the oil extraction process. What are Oil Expellers Oil expellers are machines that are used in the extraction of oil from the oilseeds namely - rapeseed, palm kernel, sunflower seeds, castor seeds, linseed, jatropha, cottonseed, groundnut, copra (coconut), mustard, seasame seed, soyabean, cocoa bean, cashew nut shell, sheanut, macadamia nuts, corn germ and other oil bearing seeds/nuts. How the Oil is Extracted Using Oil Expellers The seeds are fed from one side of the press, which then enters into the pressing chamber. The machines uses pressure and friction from the screw drives to move as well as to compress the oil seeds. The oil that is expelled then seeps through the small openings. These openings are very small which prevents any kind of solid material or residue from the seeds to mix with the extracted oil. The waste or solid residue from the seeds exits from the other end of the expeller. This leftover residue is also known as oil cakes.

Oil Expellers play a very vital role in the oil extraction process. Types of Oil Expellers Full Press Expellers Pre Press Expellers. While the full press expellers are used by small and medium oil mills, the pre press expellers are used by large scale capacity oil plants. Maximum oil is extracted from the oil seeds in the full press process, leaving the oil cakes with just about 5% to 8% of oil content. Whereas in the solvent extraction process, the oil cakes contain about 15% to 20% of oil, which are then fed into the solvent extraction plant so as to extract the remaining oil from the cakes. The oil that is extracted with the use of Oil Expellers are completely organic and contains no chemical in it. Some Features of Oil Expellers Maximum oil yield at low operating cost They comes in different capacities. Low power consumption Can crush all type of edible and non edible oil seeds.
