Abstract

A process for extracting oil from nuts and seeds of high oil content by solvent extraction without production of a large amount of fines comprises mechanically expressing the material to reduce the oil content to about one-fourth the protein content, commnuting into fragments to pass half-inch openings, subjecting the fragments to the action of flaking rolls to convert into wide, thin flakes from .005 to .02 inches thick, and solvent extraction of the flakes. The oil content is preferably reduced to from 8 to 18 per cent of the total weight of material after the mechanical expressing step, and the moisture content of the comminuted fragments adjusted by means of live steam and by heating to a temperature of from 145 DEG F. to 200 DEG F. to form 10 to 20 per cent of such weight. The flakes may be extracted with hexane or with methanol. In one test it was found that after violent agitation of the flakes with hexane, the supernatant solvent contained only one-quarter of the amount of fines occuring with unconditioned press cake. Examples of the extraction of flax seed and of decorticated peanuts with hexane are given.
