The main function of Small Scale Edible Oil Refinery decoloring process is to remove oil pigment, residual soap grain and metal ions. Under negative pressure, Made in China cooking oil refinery machine the mechanical mixing method combined with steam mixing will improve the decoloring effect. Shandong Leader Machinery Co.,ltd. The degummed oil firstly enters into the heater to be heated to the appropriate temperature (110°C), and then Small Scale Edible Oil Refinery goes to the bleaching earth mixing tank. Made in China cooking oil refinery machine The bleaching earth is delivered from the low bleaching box to the temporary tank by wind. The bleaching earth is added by automatic metering and is interlockingly controlled with the oil. Small Scale Edible Oil Refinery The oil mixed with the bleaching earth overflows into the continuous decolorizer, which is stirred by non-powered steam.Shandong Leader Machinery Co.,ltd. The decolored oil enters into the two alternate leaf filters to be filtered.

1.Why does the crude oil need the refinery process?
The crude oil( vegetable oil, such as sunflower seed oil, tea seed oil, groundnut oil,
cottonseed oil, rice bran oil, soybean oil, corn oil and palm oil ) have impurities of
oil, such as, fatty acid, phosphatide, metal ion, pigment, oxide, solid particle and
volatile gas,which will affect the oil colour ,smell ect. So it must need to remove
those impurities,then you can get the standard oil.
2.What is the refinery process?
a.Refining section: used to P-acid de-gumming, alkali refining de-acid and water rinsing.
b.Decoloring section: used to remove off pigments, bleaching oils and grease dehydrate,
make the oil lucency
c.Deodorizing section: to remove off the odor components in oil, let the oil have a good smell.
d.Dewaxing section(only for rice bran ,sunflower,cottonseed oil): used to remove off the wax
in the oil, in order to get the high quality oil.
e.Fractionation section(only for palm oil ):used to get different melting point's palm oil product,
like 8 ℃,10 ℃,14 ℃,18 ℃,24℃,33℃,44 ℃,55 ℃ ect.

Shandong Leader Machinery Co.,ltd. Add the required antioxidant and flavor agent, and then cool the oil below 50°C and store it. Small Scale Edible Oil Refinery Such volatiles as FFA from the deodorizing system are separated by the packing catcher Small Scale Edible Oil Refinery, and the separated liquid is FFA at low temperature (60-75°C). When the liquid level in the temporary tank is too high, the oil will be sent to the storage tank Made in China cooking oil refinery machine. Our company Shandong Leader Machinery Co.,ltd. has applied the automatic control system Small Scale Edible Oil Refinery with advancedness, security, reliability into the pretreatment, extraction, refining and fractionation in large oil plants. For Made in China cooking oil refinery machine application in automatic control system, Small Scale Edible Oil Refinery can control the production in the entire workshop and monitor the operational status of each device by controlling the computer terminals in the room. One person only can operate the entire workshop Small Scale Edible Oil Refinery, with efficient production management. Made in China cooking oil refinery machine has reduced the production cost greatly and improved the management efficiency.
