Title: Method for preparing edible oil

Abstract: Oil is extracted from vegetable material, such as cottonseed, rapeseed, safflower seed, sunflower seed, and linseed, by mechanically expelling crude oil from the vegetable material and then chemically extracting crude oil from the pulp cakes produced in the expelling step by using a suitable solvent. After the expelling step the oil is separated from the cakes and, thereafter, the mechanically expelled crude oil is passed through a layer of the cakes prior to at least a portion of chemical extraction to filter fine sediment from the expelled oil and thus eliminate separate fine sediment filtering steps of the mechanically expelled crude oil.
