3. Oil Refinery Process of Rapeseed Oil 

1) continuous alkali refining shortens contact tome between oil and lye,which reduces oil saponification state,lowers refining consumption,and improves efficiency;

2) decolorization craft adopts technology of combining premixing and steam mixing bleaching,which improves bleaching efficiency,saves consumption of bleaching clay, and it is simple and convenient to operate ; besides,negative pressure state avoids oxygen in the air from contacting with hot oil,thereby ensuring oil product quality ,inhibiting with hot oil,thereby ensuring oil product quality,inhibiting acid value to rise again,and lowering peroxide value;

3) physical refining section adopts new type continuous deacidiffication and deodorization craft,which is applicable for vegetable oil of high acid value and low resin content,the actual production proves its most obvious advantages as following: strong deacidiffication ability ,excellent hot bleaching effect,high refining rate ,good oil quality etc.
