Hydration Deguming & Alkali Refining Deacidification Process
Neutralization: the crude oil is output by the oil feed pump from the oil tank, and next enters the crude oil heat exchanger to recover part of heat after metering and then is heated to the required temperature by the heater. After that, the oil is mixed with the metered phosphoric acid or citric acid from phosphate tank in the gas mixture (M401), and then enters the conditioning tank (R401) to make the non-hydratable phospholipids in oil change into the hydratable phospholipids. Add the alkali for neutralization, and the alkali quantity and alkali solution concentration depend on the quality of the crude oil. Through the heater, the neutralized oil is heated to the temperature (90°C) suitable for centrifugal separation to remove the phospholipids, Auxiliary Machine For Oil PressA and other impurities in the crude oil. Then the oil goes to the washing process.
Washing: there is still about 500ppm soap in the neutralized oil from the separator. To remove the remaining soap, add into the oil about 5~8% hot water, with water temperature 3~5 °C higher than the oil generally. To achieve more stable washing effect, add phosphoric acid or citric acid when washing. The re-mixed oil and water in the mixer is heated to 90-95°C by the heater, and then enters the wash separator to separate the remaining soap and most water. The water with soap and oil enters into oil separator to separate out oil in the water. Further catch the oil outside, and the waste water is discharged to the sewage treatment station.
Vacuum drying stage: there is still moisture in the oil from the wash separator, and the moisture will affect the stability of the oil. So the oil at 90°C should be sent to vacuum drier to remove the moisture, and then the dehydrated oil goes to the decoloring process. Finally, pump out the dry oil by canned pump.If you are interested in our company,please feel free to contact Ms. Myra for a quotation,(Tel/whatsapp:0086-18363092712, Email:[email protected],Skype:leaderfoodmachine2).You will get superior service,and Shandong Leader Machinery Co.,Ltd. produce Shandong LD rapeseed/rice bran/palm oil refining machine with high quality, high performance and the best prices.
Continuous Refining Decoloring Process
The main function of decoloring process is to remove oil pigment, residual soap grain and metal ions. Under negative pressure, the mechanical mixing method combined with steam mixing will improve the decoloring effect.
The degummed oil firstly enters into the heater to be heated to the appropriate temperature (110°C), and then goes to the bleaching earth mixing tank. 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.
The oil mixed with the bleaching earth overflows into the continuous decolorizer, which is stirred by non-powered steam. The decolored oil enters into the two alternate leaf filters to be filtered. Then the filtered oil enters the decolored oil storage tank through the security filter. The decolored oil storage tank is designed as the vacuum tank with the nozzle inside, so as to prevent the decolored oil contacting with the air and influencing its peroxide value and color reversion.

oil refining machine Process of making Purity cooking oil
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
Oil pigment can make grease with darker colors, affect the oil appearance, adsorption will be used to remove it from the oil.
Deguming process
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 adsorption 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 adsorb 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 adsorb protein and a small amount of mechanical impurities then generate precipitation.
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.
Decoloration process
Decolorization reasons: 1,impact the appearance of oil. 2, part of the pigment is poisonous.3, the food oil processing needs decoloration.
Deodorization process
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.
Deodorizing purposes
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 .
Dewaxing process
The wax is a combination of monocarboxylic acids and monohydric alcohol. Having a higher melting point (78-82 ° C).
Dewaxing reason( wax exists primarily in palm oil 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 great different melting point between oil and wax, through crystallization by cooling, then make the oil and wax separated by filtration or centrifugal separation .
