Refining of crude palm kernel oil refining factory
Product Description
1. Crude palm kernel oil refining flowchart:
Usually there are two kinds of edible oil refining method,chemical oi refining and physical oil refining.
Oil refinery plant refers to a series of refining processes that can remove phospholipids, FFA, pigment, off-flavor and other impurities in the oil. Edible oil refinery or vegetable oil refinery is essential to ensure removal of gums, waxes, phosphatides and free fatty acid (F. F.A.) from the oil. To impart uniform colorby removal of coloring pigments and to get rid of unpleasant smell from the oil by removal of odiferous matter.
The purpose of oil refining:
To make edible oil meet people’s edible,and to remove the impurities in the crude oil.
There is much impuries in crude oil,such as phosphatides,oxidized product,gums,free fatty acids,colour bodies,trace metals,water,hydrocarbons,solvents,polymerized product.
2. Machine to refine cooking oil parts:
(1) Refining section: used to P-acid de-gumming, alkali refining de-acid and water rinsing.
(2) Decoloring section: used to remove off pigments, bleaching oils and grease dehydrate.
(3) Deodorizing section: to remove off the odor components in oil.
(4) Dewax: used to remove off the wax in the oil, in order to get the high quality oil.
(5) Heat-transfer oil stove: supply each device production needing heat energy, temperature reach above 280°C.
(6) Steam generator: produce the needing steam for de-odoring and distillation.
(7) Vacuum pump: supply needing vacuum for dehydrate, de-color, de-odor. Vacuum degree can reach above 755mm Hg.
(8) Press filter: filter clay, filter out clear oil.
(9) Air compressor: blow dry bleached clay, blow empty the leftover oil in the press filter.
3. Machine to crude oil refining process:
Step 1.Degumming with water to remove the easily hydratable phospholipids and metals.
Step 2.Addition of a small amount of phosphoric or citric acid to convert the remaining non-hydralable phospholipids (Ca, Mg salts) into hydratable phospholipids.
Step 3.Neutralising of the free fatty acids with a slight excess of sodium hydroxide solution, followed by the washing out of soaps and hydrated phospholipids.
Step 4.Bleaching with natural or acid-activated clay minerals to adsorb colouring components and to decompose hydroperoxides.
Step 5.Deodorising to remove volatile components, mainly aldehydes and ketones, with low threshold values for detection by taste or smell. Deodorisation is essentially a steam distillation process carried out at low pressures (2-6 mbar) and elevated temperatures (180-220°C).
4. Crude oil refining consumption:

Steam |
≤300kg/per ton oil |
Alkali consumption |
1.6-2.2kg/per ton oil FFA+0.7kg |
Bleaching earth |
3-20kg/per ton oil(it is need to increase or decrease properly according to the color and luster requirements) |
Power consumption |
≤22 degree/per ton oil |
Coal consumption |
10-20kg/per ton oil |
Oil content in bleaching oil |
≤ 23% |
Phosphoric acid |
