Solvent-extracted rapeseed meal. Rapeseeds contain 40-45% oil and yield about 55-60% oil meal when fully extracted by crushing followed by solvent extraction (see figure above).The main steps of this process are seed cleaning, seed pre-conditioning, rolling and flaking, seed cooking and pressing to mechanically remove a portion of the oil, solvent extraction (hexane) of the press-cake to ...

A process for extracting oil from oil-bearing materials, such as vegetable oil bearing seeds and plant materials, is disclosed. The process comprises adding crude oil, water and a reagent to the oil-bearing materials to form a slurry. Subsequently, a resultant oil is extracted from the slurry. The process provides for treating the oil-bearing materials in a screw extruder.
