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 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
Extraction Process 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.
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.
