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.
What are Oil ExpellersOil 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 ExpellersThe 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 Extraction ProcessThe 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.Types of Oil ExpellersFull Press ExpellersPre 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 ExpellersMaximum oil yield at low operating costThey comes in different capacities.Low power consumptionCan crush all type of edible and non edible oil seeds.For more information of oil expellers and to contact their manufacturers and suppliers from India, visit: http://www.oilmillmachinerysuppliers.com/
Comprehensive Guide to Oil Filter Presses: Types and Technical Insights
Oil filter presses play a crucial role in the purification of extracted oil, ensuring that it is free from impurities and suitable for consumption or further processing. These devices are essential in the oil production industry, providing a means to separate solids and precipitates from various types of oils. The quality of filtered oil is often so high that additional refining may not be necessary, although some oils, like those from cotton seeds, do require further treatment. This guide delves into the technical specifications, various types, and key features of oil filter presses, offering insights into their operation and efficiency.
