METHOD TO ENHANCE GRAIN PROCESSING AND DIGESTIBILITY
A method for processing grains, crop residues, agricultural waste materials, processing waste materials, or mixtures thereof, is provided that includes using a rotary biomass dryer to process the materials and subjecting them to a steam explosion in order to form a processed material that exhibits an increase in porosity and/or absorption potential.
1 . A method for processing grains, crop residues, agricultural waste materials, processing waste materials, or mixtures thereof, the method comprising:
providing a rotary mass dryer;
providing at least one processable material, the at least one processable material being selected from the group consisting of grains, crop residues, agricultural waste materials, processing waste materials, and mixtures thereof;
placing the at least one processable material into the rotary mass dryer; and
subjecting the at least one processable material to a steam explosion in order to form a processed material,
wherein the processed material exhibits an increase in porosity and/or absorption potential.
2 . The method according to claim 1 , wherein the processed material exhibits an increase in one or more of nutritional value, ethanol yield, weight, or digestibility.
3 . The method according to claim 1 , wherein the agricultural or processing waste material includes at least one selected from the group consisting of nut shells, coffee grounds, and wood waste.
4 . The method according to claim 1 , wherein the increase in porosity of the processed material comprises at least a 10% increase a median diameter of pores present in the processed material.
5 . The method according to claim 4 , wherein the increase in median diameter of the pores in the processed material is greater than about 20%.
