Rapeseed oil makes large proportion of edible oil market.It has high content of linoleic acid and other unsaturated fatty acids and vitamin E and other nutritional ingredients which is effectively in Soften blood vessels and anti-aging effect For rapeseed and canola applications, our company provides complete preparation systems for pre-pressing and full pressing.


1. Oil pretreatment and oil prepressing equipment of  Rrapeseed Oil Extraction Machine 

Process characteristics:
1) provide the appropriate production environment

2) try our best to minimize grease total losses, improve the oil  yield , increase production and improve the quality of oil and cake meal;

3) increase s comprehensive utilization for the impurities and residues;

4) pretectly match oil extraction production line, design different production process according to different raw material.

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.
