Grain bulk densifying die apparatus and method

An apparatus for producing a densified grain comprising:

• a die assembly, the die assembly comprising:
• a die body having a first annular end, a second end having a die adapter for receiving a grain material, and a substantially triangular nose cone member at a middle portion thereof, wherein the grain material received by the die adapter is forced through an extrusion passageway that evenly distributes the grain material into each of a plurality of orifices thereby producing a high density grain material;
• a die head comprising at least one plate including the plurality of orifices, each orifice extending out through the die head such that each orifice defines a plurality of die passageways within the die head for the grain material to pass there through, the die head being mounted to the die body with at least one first fastening mechanisms thereby enclosing the substantially triangular nose cone configured as a flow-direction mechanism to provide the extrusion passageway for the grain material, wherein the grain material received by the die adapter is forced through the extrusion passageway that evenly distributes the grain material into each of the orifices thereby forming the grain material into a shaped grain material having a predetermined density before the grain material exits the die head;
• each die passageway comprises:
• an inlet surface that tapers downwardly;
• a plurality of funnel-shaped structures extending from the inlet surface, each funnel-shaped structure having a wide inlet and inwardly sloping sides extending downwardly;
• a constricted passage extending from the inwardly sloping sides of each funnel-shaped structure, the constructed passage having a constricted diameter that is smaller than a diameter of a final product, wherein the constricted passage is configured having a linear length sufficient to enable the grain material to stabilize to the constricted diameter as the grain material travels therein;
• and
• a relief section downstream of the constricted passage, wherein the relief section having an enlarged diameter that defines the diameter of the final product, and the relief section extends to an outlet of the die head;
• a cooling assembly for cooling the shaped grain material, the cooling assembly comprising:
• a cooling chamber having a first end, a second end, a first coolant opening, a second coolant opening and a coolant passage that extends from the first end to the second end, the first and the second coolant openings configured to receive at least one coolant to the coolant passage, the cooling chamber comprising:
• a first plate member positioned at the first end, the first plate member being mounted to the die head with at least one second fastening mechanisms;
• a second plate member having a plurality of exit ports positioned at the second end;
• at least one cooling tube having an inlet end for receiving the shaped grain material and an outlet end, the at least one cooling tube being horizontally placed inside the cooling chamber, and the inlet end of the at least one cooling tube is connected to at least one of the plurality of the die passageways of the die head, the outlet end of the at least one cooling tube is connected to at least one of the plurality of the exit ports of the second plate member of the cooling chamber, the cooling chamber cools the shaped grain material by passing the shaped grain material through the at least one cooling tube;
• a break-off assembly for breaking off a preselected length of the shaped grain material, the break-off assembly comprising:
• at least one stud member attached to the second plate member at the second end of the cooling chamber;
• and
• at least one cone breaker being threaded to the at least one stud member.
