The main purpose of vegetable oil refining plant is to remove non-oil element existing in crude oil, such as, FFA, metal ion, colloid and some pigment.
1, Degumming is one of the basic technical problems in oil refining. The presence of colloid not only reduces the use value and storage stability of oil, but also has a series of adverse effects in refining process, which leads to lower quality of the final oil. Therefore, the gum must be removed first.
2, the quality control of oil products. In order to achieve the quality index, according to the quality of the crude oil under different circumstances, we must take the corresponding filtration, degumming, deacidification, decolorization, deodorization and degreasing (wax) and other refining means.
3, we must strictly control the process conditions, select the appropriate refining accessories, control the refining consumption.
