Chemical refining is the use of NaOH to neutralize the acidic substances in the process of a neutralization and produce byproduct soap feet;
Physical refining is the way of using high temperature distillation according to the boiling point of the rancidity oil evaporation processing methods, distillation by-product fatty acids .
Edible Oil Refinery Process – Degumming
Hydration Degumming: Hydration degumming mean adding into some hot water and controlling the corresponding conditions to make the hydrosol agglomerated, deposited and then separate them.
Special Degumming: The technology is specially developed to meet the demands of physical refining for edible / vegetable oil refining.
Edible Oil Refining Process – Bleaching
High activity clay is added into oil. Mix and heat mixture of oil and clay to make the small particle of pigment absorbed on the crystal of clay. At last filter the oil. Mechanism, liable performance, well configured equipment.Bleaching Tower and Filters ensures excellent bleaching and separation effect.
Edible Oil Refining Process – Deodorizing
Combined deodorizing is the latest technology, which improves oil flexibility significantly. Detailed deodorizing process in the entire oil refining plant is: Most heat of bleached oil is recovered by Heat Exchangers.
