Peanut oil refining machine

From crude peanut oil to standard edible oil needs to go through four basic stages of degumming, deacidification, decolorization and deodorization.

Step1. Degumming

In this step, we add hot water to dissolve colloidal impurities in crude peanut oil to remove excess phospholipids and make the color more vivid and obtain purer peanut oil;

Step 2. Deacidif ication

Due to the crude oil after degumming still contains excessive free fatty acids ， so we need to add alkali to deacidify, let out the soap stock after settling and obtain acid-base neutralized refined peanut oil;

Step3. Decolorization

Then, we add white clay as an adsorbent to remove pigment in the crude oil and filter with a leaf filter after full reaction to improve the color of the oil and to obtain refined bleached peanut oil.

Step4. Deodorization

Finally, the odor and part of free fatty acid in crude peanut oil were removed by distillation to improve the quality of the peanut oil further and obtain edible oil.  After this series of processing, we will finally get edible peanut oil.
