Groundnut oil refinery production line is using physical or chemical method to remove the harmful substances in crude groundnut oil and make the refined groundnut oil qualitified the national standard. So the groundnut oil from pressing workshop and solvent extraction workshop are both crude groundnut oil, and can not be ate directly. If you want to get high quality refined groundnut oil, you should consider setting up a groundnut oil refinery line.
Totally speaking, the groundnut oil refinery production line can remove the impurity in the crude groundnut oil, including the phosphoric acid, free fatty acid, pigment, odor, and other impurities in the crude groundnut oil.
The complete groundnut oil refinery process mainly includes degumming, deacidification, decoloration and deodorization process. All this process can make the groundnut oil good for human's health and easy to storage.
Various crude vegetable oil can be refined by DOING Brand oil refinery machine
According to the input capacity, you can choose 1-20tpd batch type groundnut oil refinery production line, 20-50tpd semi-continuous groundnut oil refinery production line or 50-600tpd fully continuous groundnut oil refinery production line. What's more, our equipment is suitable for refining various crude vegetable oil. For example, rice bran oil, peanut oil, soybean oil, sunflower oil, palm oil and so on.
Main process in groundnut oil refinery production line:
 |
1. Degumming and deacidification process: Degumming is using phosphoric acid, water to react with crude groundnut oil and then separate phosphatide from oil. But in order to reduce more phosphatide, after enough phosphoric acid treatment, adding alkali inside oil to neutralize free fatty acid, and washing before gum separation. This process in groundnut oil refinery production line is called deacidification. |
 |
2. Decolorization process Decolorization is using clay to bleach oil. In this step of groundnut oil refinery production line, clay will absorb dark colorant of oil. The quantity of clay is depending on the deepness of crude oil. After bleaching, used clay will be screened out by vibrating screen. |
 |
3. Deodorization process This step in groundnut oil refinery production line is to remove some unnecessary odors from crude groundnut oil. Normally for chemical oil refining, it adopts plate deodorizing tower using high temperature steam to remove odors. |
 |
4. Filtering process: After getting the deodored oil, in order to get the most purified groundnut oil, we usually using the SS safety filter to filter refined groundnut oil once again. |
After above steps, the final product is refined groundnut oil, which can reach the level of consumption. If you want to know more information about groundnut oil refinery production line, please feel free to contact us! Doing Company will get in touch with you as soon as possible.
