Whatare Oil ExpellersOilexpellers are machines that are used in the extraction of oil fromthe oilseeds namely - rapeseed, palm kernel, sunflower seeds, castorseeds, linseed, jatropha, cottonseed, groundnut, copra (coconut),mustard, seasame seed, soyabean, cocoa bean, Ultrasonic Fabric Sewing Machine Manufacturers cashew nut shell,sheanut, macadamia nuts, corn germ and other oil bearingseeds\/nuts.Howthe Oil is Extracted Using Oil ExpellersThese eds are fed from one side of the press, which then enters into thepressing chamber. The machines uses pressure and friction from thescrew drives to move as well as to compress the oil seeds. The oilthat is expelled then seeps through the small openings. Theseopenings are very small which prevents any kind of solid material orresidue from the seeds to mix with the extracted oil. The waste orsolid residue from the seeds exits from the other end of theexpeller. This leftover residue is also known as oil cakes. OilExtraction ProcessThe process of oil extraction has been existent from very early times. Inthose days, the seeds were merely cleaned and grinded with the use ofgrinders or stone mills. With the advancement of science andtechnology, the use of machines like Screw Presses or Oil Expellerswere started for expelling or extracting oil from oil seeds and nuts.Oil Expellers play a very vital role in the oil extractionprocess.Typesof Oil ExpellersFullPress ExpellersPre Press Expellers.While the full pressexpellers are used by small and medium oil mills, the pre pressexpellers are used by large scale capacity oil plants. Maximum oil isextracted from the oil seeds in the full press process, leaving theoil cakes with just about 5% to 8% of oil content. Whereas in thesolvent extraction process, the oil cakes contain about 15% to 20% ofoil, which are then fed into the solvent extraction plant so as toextract the remaining oil from the cakes. The oil that is extractedwith the use of Oil Expellers are completely organic and contains nochemical in it.
