Abstract
In the extraction of vegetable oils by pressure, the raw material, e.g. powdered soya beans, is subjected to a preliminary heat treatment with an oil whereby moisture is evaporated therefrom and the vegetable tissues are loosened, and thereafter the oil is removed, e.g. in a centrifuge. The oil used is preferably identical with that extracted, or is suitable for admixture therewith, e.g. hardened fatty oil, liquid animal or vegetable or paraffin oils.
