Abstract:
1. A method of kernel fractionation, comprising: a) fracturing a plurality of corn kernels to generate a plurality of corn particles, wherein said plurality of corn particles comprise a dry mixture of a plurality of corn bran particles, a plurality of corn germ particles, and a plurality of corn endosperm particles; b) fractionating said dry mixture of said plurality of corn bran particles, said plurality of corn germ particles, and said plurality of corn endosperm particles into a corn germ fraction, a corn endosperm fraction, and a corn bran fraction; c) separating said corn endosperm fraction into a first endosperm stream and a second endosperm stream, said first endosperm stream a non-extracted endosperm stream; d) establishing an amount of said second endosperm stream inside a corn endosperm extraction zone; d) fluidicly engaging an amount of extractant to said amount of said second endosperm stream inside said extraction zone; e) extracting an amount of corn oil from said amount of said second endosperm stream fluidicly engaged by said amount of extractant to produce an extracted endosperm stream; and f) generating an amount of endosperm-germ cake from said extracted endosperm stream containing a reduced amount of corn oil.
