The present invention provides a process to remove the germ from the endosperm of a corn kernel. The apparatus of the present invention comprises frictional cylindrical rollers, each roller rotating about an axis, the axis of the rollers substantially parallel, and the direction of rotation being opposing. The roller bodies having a rubberized covering, rotate with differing surface velocities and are tensioned such as to impart low-impact friction forces to corn kernels drawn between the roller covers. The process of the present invention includes a tempering step comprising adding an amount of moisture to the corn by wetting and soaking the corn; a polishing step for removing bran layers from the corn; a second tempering step comprising adding an additional amount of moisture to the corn by wetting and soaking the corn; and a friction step to remove germ from the endosperm.
