Abstract:
1. A corn milling process, comprising: fracturing corn kernels into relatively large particles at least some of which comprise an endosperm portion of the kernels and a germ portion of the kernels; and passing the fractured particles between a pair of counter-rotating rollers, each of which presents fine corrugations of the type that normally characterizes the end of a differential corn milling process, one of said rollers rotating at a first speed and the other of said rollers rotating at a second speed, wherein the ratio of said first speed to said second speed is between 1.1:1 to 1.4:1, said rollers being spaced apart a distance to grind the endosperm portion of the particles while avoiding substantial penetration of said roller corrugations into the germ portion of the particles thereby separating the germ portion and endosperm portion of the particles without reducing the size of the germ portion.
