oil extraction process introduction:

Extraction is a chemistry way to extract oil from soybean . It makes use of Solvent  Extraction Principles ,

which  makes Number 6 solvent oil come into soybean cake .Then oils and fats is dissolved from Mixed oil 

When we finished the soybean pretreatment , the moisture of soybean need to be 90%.So we must control 

The oil refinery process:

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 color by removal of coloring pigments and to get rid of unpleasant smell from the oil by removal of odiferous matter.

Main process 

1.    Filtration: The purpose of this step is to remove the granular impurities in palm oil.

2.    Degumming: Pumping crude oil into oil refining tank, stirring quickly, andsimultaneously heating by steam or heat-transfer oil(in coiled heater). Then add some hot water. You should control the water amount, temperature and water adding speed. If phospholipid lasts long suspended in oil, which is hard to gather to make flocculent precipitate. We can rise up the speed of adding water, conversely slow down. At the meanwhile, adding alkali to remove the FFA. For the batch type and semi-continuous type refinery, they will adopt precipitation separation method, continuous refineries will adopt centrifuge separation method.

3.    Decolorization: Inhale definite amount of decoloring agent(floridin or acticarbon)into the oil, continuously stirring and heating for 25min. After that, pump the mixture of oil and floridin into filter to separate oil and floridin.

4.    Deodorization: Pump and heat decolorized oil, when oil temperature reaches above100°C, injecting the direct steam to take the odors away. We can get refined palm oil, which is edible at this step.

5.    Fractionation: This is very important process in palm oil refining, But before this step, we have get edible palm oil, in another word, if not for special usage, this step could be cancled in palm oil refining.
