Safflower oil extraction

The oil of safflower is been extracted from the ghaana process .
Safflower seeds have 30-35% oil content in it.
In order to improve the extraction of oil from safflower seeds, the waste which is in the form of cake of safflower seeds produced during the ghaana process can be treated in the solvent extraction plant .
Here hexane can be used as solvent and the waste generated here i.e. DOC(De-Oiled Cake) can be used as fodder in poultry farms.
The quantity of oil can also be increased by running the extractor at slow speed .
