One-pass dry grain and corn fractionation

A dry, one pass processing method for obtaining pre-processing liberated fractions from cereal kernels, the method comprising:

• moisturizing (S1) bran layers of the kernels by a mist of droplets of water,
• comminuting (S2) the kernels utilizing by a comminution reactor (610) comprising a spinnable shaft (681) and two or more processing chambers (682), separated by segmented plates (683), wherein each processing chamber (682) comprises a rotor disc (684) attached to the shaft (681) and one or more vortex generators (685) placed in a side wall (686) apex corner of the processing chambers (682),
• wherein the kernels are fed into the comminution reactor (610) and small bran particles and large bran particles, whole germ, small germ and broken germ, soft endosperm flour, and medium and large hard endosperm particles are liberated from the kernels by means of a chaotic vortex flow of the kernels, forming liberated products in the processing chambers (682),
• removing the small bran particles and the large bran particles;
• removing the small germ, the whole germ, and the broken germ;
• grinding (S51) the medium hard endosperm particles, the large hard endosperm particles, and the soft endosperm flour together in the comminution reactor (610), forming a high starch content mash of suitable size for enzymatic conversion of starch to sucrose.
