LeaderE Refined Sunflower Cooking Oil Mill
What is oil refining
The process of refining of crude oil and removing impurities is known as refining of the fats and oils.
What is crude oil
By pressing or leaching, the unrefined vegetable fats and oils are commonly known as crude oil.
The main component of crude oil
Mixed fatty acid triglycerides, commonly known as the neutral oil. Phospholipids, free fatty acids, pigments, peroxides, waxes and various mechanical impurities. The presence of these impurities is bad for taste , processed and storage of the fats and oils.
Mechanical impurities mixed with oil
Refers to the sediment, blank powder, cake, fiber, grass clippings and other solid impurities in the oil producing and storing process. Such impurities are not soluble in oil, so it can be removed by filter and settlement .
Oil pigment can make grease with darker colors, affect the oil appearance, LDorption will be used to remove it from the oil.
Main process of refining
The process of colloid impurities removal in oil called degumming, the colloidal impurities in crude oil mostly is phospholipid, so deguming is often called the dephosphorization . Degumming method include hydration method, adding acid method. heating method, and the LDorption method.
Alkali refining deacidification
It refers to the refining process that saturate the free fatty acids with alkali, then generate fatty acid salts (soap) and water, the soap LDorb a portion of impurity then settling out from the oil.
The precipitate formed called soapstock. The alkali used for saturating the free fatty acids is NaOH or Na2(CO)3 or Ca(OH)2 and so on. the oil industry generaly use caustic soda.
The alkali refining itself has the synthetic action of deacidification, degumming, off impurities and decoloration.
1. The alkali saturate the fatty acid and generate the soapstock precipitation.
2. The soapstock LDorb protein and a small amount of mechanical impurities then generate
3. Saponify part of the phospholipid, as to the crude oil with high acid value and less
phosphorus,we can use the alkali refining to dephosphorize and deacidify in the meantime.
Decolorization reasons: 1, impact the appearance of oil. 2, part of the pigment is poisonous.3,
the food oil processing needs decoloration.
The pure triglycerides is no odor. the Oxides of non-glyceride (ketones, aldehydes,
hydrocarbons) and unsaturated fatty acid glycerides have odor. odor generated in the oil making process, such as the odor in the leaching grease solvent, soap odor in the alkali refining oil and clay odor in decolorization oil.
1. The presence of odor substances.
2. Some residual pigment.
3. Remove the free fatty acids, mainly remove the substances that caused the odor. Remove all
the bad smell, the process called deodorizing .
The wax is a combination of monocarboxLDic acids and monohydric alcohol. Having a higher melting point (78-82 ÃÂÃÂ° C).
Dewaxing reason ( wax exists primarily in corn germ oil, sunflower oil, rice bran oil)
Hard to dissolve in the oil,and the human body can not absorb . it is mist in the oil under the room temperature, the oil becomes cloudy. The waxy existence impact on oil taste and oil transparency, also affect the processing, should be removed from the crude oil.
Oil dewaxing is taking the LD different melting point between oil and wax, through crystallization by cooling, then make the oil and wax separated by filtration or centrifugal separation .

LeaderE Refined Sunflower Cooking Oil Mill produced and supplied by shandong leader machinery Co.,Ltd.
Crude Oil Refining Machine can be used in black engine oil,Crude oil and plastic oil, etc, by distilled catalyst to get gasoline and diesel oil. The waste oil pump into the distillation of Crude Oil Refining Machine , through the coal (or fuel oil) heating to working temperature, the maximum working temperature by LeaderE Refined Sunflower Cooking Oil Mill is the 410 degree and the required gasoline and diesel oil can be obtained after catalytic distillation. When the reaction of waste oil in reactor of LeaderE Refined Sunflower Cooking Oil Mill is complete, stop heating, and remove residue from the tank of bottom, then Crude Oil Refining Machine can be used by LeaderE Refined Sunflower Cooking Oil Mill again.
