Method and system for corn fractionation
First Claim
Patent Images
1. A process for fractionation of corn, the process comprising the steps of:
- preparing the corn for extraction;
without separating germ from the prepared corn, extracting oil from the prepared corn with a solvent to provide an extracted corn-solvent mixture;
separating the extracted corn-solvent mixture into at least two streams, one including an extract comprising the oil and the solvent, and the other comprising de-oiled corn solids and adsorbed solvent;
membrane processing the extract to separate the solvent from the oil;
desolventizing the de-oiled corn solids from the other stream to substantially remove the solvent and provide-deoiled, desolventized corn solids;
resuspending said de-oiled, desolventized corn solids in water; and
separating one or more of fiber, starch and protein from the suspended de-oiled, desolventized corn solids to produce one or more corn products.

Abstract
Methods and apparatus for processing corn into one or more corn products. Oil is extracted from corn or corn products or by-products with a solvent. The corn-solvent mixture is separated into streams, one of which preferably includes an extract containing at least oil and solvent, and another containing de-oiled corn solids and adsorbed solvent. The solvent is separated from oil, and the de-oiled, desolventized corn solids are processed to provide one or more corn products.
