What is the process of producing refined edible oil?

In order to improve the quality of edible oil, ensure health, mild taste, and nutritional value of the edible oil, the most edible oil producers choose to refine the crude edible oil into refined edible oil, then sell them. If you also want to know the process of producing refined edible oil, here is an overview of the edible oil refinery process:

1.Degumming:

Degumming equipment is the first tool used in the process of producing refined edible oil. Pumping crude edible oil into oil refinery tank, stirring quickly, and simultaneously heating by steam or heat-transfer oil(in coiled heater). Then add some hot water to remove phospholipid in crude edible oil. But during edible oil degumming process, 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. Then we can remove the gums in the crude edible oil by precipitation.

For the batch type and semi-continuous type edible oil refinery equipment, our Henan Glory Company adopts precipitation separation method, as for continuous edible oil refining equipment, we adopts centrifuge separation method. If this is your first time entering this industry, it is recommended that you choose batch type edible oil refinrery equipment with low investment, small footprint, easy to operate. The cost of batch type edible oil refinery equipment depends on the heating method of the equipment and the processing tonnage.

2.Deacidifying

Deacidifying is usually the tool used in the process of producing refined edible oil, which is aimed to remove free fatty acids from crude edible oil. We usually add the food grade alkaline to the degummed oil for acid-base neutralization reaction to remove the free fatty acids, and then remove the soapstock by heating and natural sedimentation.

3.Decolorizing

Decolorizing is usually used in the process of producing refined edible oil to remove impurities such as pigments, metals, and residual soap from the edible oil. Inhale definite amount of decoloring agent(white clay or acticarbon)into the refined edible oil, continuously stirring and heating for a period of time. After that, pump the mixture of oil and white clay into filter to separate oil and waste white clay.

4.Deodorizing

Deodorizing process can remove odors and flavors from the edible oil. It refers to pump decolorized edible oil into deodorizing equipment, when oil temperature reaches above 100℃, injecting the direct steam to take the odors away. Our company's refinery equipment adopts 304 stainless steel in the deodorizing section to meet the production needs and ensure the refinery quality.
