Abstract:
    There is disclosed a method of extracting components from particulate materials. The method includes the steps of mixing the particles with a polar solvent to provide a slurry. The slurry is then passed through an extraction zone. A non-polar solvent is passed countercurrently to the slurry through the extraction zone. The non-polar solvent has a different density from the polar solvent and is substantially immiscible with the polar solvent. This process is particularly beneficial for use in the extraction of ground oil-seed particles.
