Abstract: A system of crushing and processing grain without destroying germ pouches in the grain by: (a) pneumatically transporting grain from truck to a cyclone and processing bin to a pre-crushing area; (b) dropping the grain from the pre-crushing area down into a single pass crushing machine while simultaneously releasing air from the pre-crushing area such that the grain falls from the pre-crushing area into a single-pass crushing machine under the force of gravity and is not blown down into the single-pass crushing machine; and then (c) crushing the grain in the single-pass crushing machine that has three or more roller pairs such that from one successive roller pair down to the next roller pair the grain is crushed smaller and smaller when moving downwardly in the machine. Also included are air locks with attached dust sleeves.

Abstract: A method of crushing and processing grain without destroying germ pouches in the grain, by: (a) crushing grain in the primary single-pass crushing machine, and then sieving the grain to sort the grain into two or more particle sizes; (b) transporting larger sized particles from the sieved grain into a secondary single-pass crushing machine; (c) crushing the larger sized particles of grain in the secondary single-pass crushing machine; (d) sieving the grain crushed in the secondary single-pass crushing machine to sort the grain into two or more particle sizes; and then (e) combining smaller sized particles sieved from the primary single-pass crushing machine with smaller sized particles sieved from the secondary single-pass crushing machine.
