Description

Technical Field

[0001] The utility model relates to the field of edible oil processing, in particular to edible oil refining equipment. Background Art

[0002] Decolorization is a crucial refining step in edible oil production, aiming to improve the oil's quality and appearance by removing pigments and impurities. Conventional decolorization processes typically utilize an adsorbent, such as activated carbon, in contact with the oil in a decolorization tank to absorb and remove the pigment. However, these traditional methods have several drawbacks, including issues such as high temperatures and increased oxidation associated with atmospheric pressure decolorization, as well as incomplete decolorization caused by insufficient contact between the adsorbent and the oil.
