Refining is the refinery of crude oil to remove impurities, which is conducive to safe storage, and obtain directly edible oil that meets national standards. Refining mainly includes degumming, deacidification, decolorization and deodorization processes. The smell here refers to unpleasant smell. So how to refine peanut crude oil?

Small-scale refining and degumming and deacidification are carried out at the same time. Hot water and alkaline water are added to the caustic refining tank to separate the gum and free fatty acids (FFA) in the crude oil. The next step is to obtain degumming and deacidification of relatively pure gold. Oil, the next step is to add activated clay or other adsorbents to the decolorization tank to absorb the pigment in the crude oil. After filtration, part of the moisture and unpleasant odor molecules will be evaporated in the deodorization tank in a high-temperature vacuum environment. To obtain refined oil that meets national standards, which is conducive to storage and sales. The entire refining process is roughly completed.
