Product Description

Raw Material:

The oil machine is suitable for different materials, but the process of each materials is various. If you really need to process oilseeds, welcom to know much from us. The main materials is rice bran, peanut, palm, sunflower, corn germ, soybean, sesame, cottonseeds and so on.

Groundnut oil refining process flow

Crude groundnut oil→hydration, degumming,dephosphorization →deacidification → drying →

bleaching → deodorization → refined groundnut oil.

Oil Refining Process Introduction

No.	Section Name
1	Crude oil degumming section
Add hot water and food grade phosphoric acid to mix with crude peanut oil to finish degumming, mainly removing phospholipids,protein, colloid and trace metal ions. Separate oil sediments from oil with centrifuge, then dehydrate and dry oil.
2	Deacidification section
Continuous physical deacidification method and batch chemical deacidification method are the most common deacidification methods for removing FFA. Physical deacidification method. Under high vacuum condition, adopt steam distillation method to carry FFA with steam and remove it. Chemcial refining. Add alkali to neutralize free fatty acid to form soap-stock , sedimentary soap-stock will be separated from oil.
3	Bleaching section
Mix active bleaching clay with oil under vacuum condition for adsorption bleaching, and use leaf filter to remove waste bleaching clay.
4	Deodorization section
Under high temperature and high vacuum condition,utilize water vapour distillation to remove odor of oil.
