Rice bran oil processing technology and rice oil processing equipment.
Introduce you to the processing technology of rice bran oil:
1.Crude oil filtration: Crude oil usually contains impurities such as cake residues, oil feet, soap feet, meal powder, etc., which can be removed from crude oil by physical methods such as sedimentation, filtration, and centrifugal separation.
2.Refining and degumming: The commonly used methods for degumming include hydration, acid refining and enzymatic degumming. Through these methods, phospholipids, mucus, resin proteins, sugars, and trace metals are removed from crude oil to prepare for subsequent processing.
3.Refining and deacidification: The commonly used methods for deacidification are the use of caustic soda or lye solution neutralization method to remove free fatty acids from the oil, and then wash away the soap feet and water-soluble impurities remaining in the alkali refining oil with water.
4.Drying and dehydration: The method of heating vacuum drying is used to remove the residual water in the refined oil after hydration and degumming.
5.Refining and decolorization: using activated clay aluminum silicate, activated carbon and other adsorbents to adsorb and remove pigments, gums, oxides, etc. in oil.
6.Deodorization: The principle of vacuum stripping is used to remove low-molecular odor substances, free fatty acids, monoglycerides, sulfides and pigment thermal decomposition products in oil.
7.Refining and dewaxing: Freezing crystallization or winterization crystallization method is used to remove wax or solid grease from oil.
8.Finished product filtration: Filtration equipment is used to remove solid particles in crude oil, white clay in decolorized oil, catalyst in hydrogenated oil, and impurities such as wax or solid fat to ensure the clarity of refined oil.
