Edible oil refining equipment is a kind of equipment that can deal with many kinds of impurities in crude oil. The existence of impurities in crude oil not only affects the edible value and safe storage of oil, but also brings difficulties to deep processing. Therefore, according to different requirements and uses, different equipment production lines need to be customized to meet the needs of users.

Process flow: crude oil → alkali refining → water washing → decolorization → deodorization → finished product

Deacidification by alkali refining: there are a certain amount of free fatty acids in various unrefined crude oils. The process of removing free fatty acids from oils is called deacidification

Oil decolorization: the adsorption decolorization of oil is to use some substances with strong selective adsorption on pigment to absorb pigment and other impurities in oil under certain conditions, so as to achieve the purpose of decolorization.

Deodorization of oil: the process of deodorizing substances by steam distillation under high temperature and high vacuum.
