  • Patent number: 9750268
    Abstract: An apparatus and method for processing grain material to generate a consistently high densified grain with a desired length, shape and size. The densified grain processing apparatus comprises a die assembly, a cooling assembly and a break-off assembly. The method includes receiving the grain material by the die assembly and forcing the grain material through an extrusion passageway that evenly distributes the grain material into a plurality of orifices thereby producing a high density shaped grain before the grain material exits the die assembly. A coolant is pumped to a coolant passage by means of an at least one pump and cools the shaped grain by passing the shaped grain through at least one of the cooling tube inside a cooling chamber. The break-off assembly then breaks off a predetermined length of the shaped grain.

  • Patent number: 8758004
    Abstract: An extruder comprises an extruding section, a chamber drum, and a forming section. The extruding section kneads and extrudes a kneaded material including a ceramic raw material. The chamber drum includes a first space portion which extends from the extrusion port side of the extruding section in an extruding direction and allows the kneaded material to flow in the extruding direction, and a second space portion which extends from a downstream side of the first space portion in a downward direction, allows the kneaded material to flow in the downward direction different from the extruding direction, and has a discharge port to discharge the kneaded material. The forming section includes a die through which the kneaded material discharged through the discharge port of the chamber drum is pushed out, to extrude and form ceramic formed bodies.

  • Patent number: 8668486
    Abstract: An extruder die designed to produce a spiral corn-based snack food product with consistent, tight spiral pitch and the resultant food product. The extruder die has a center post parallel to the flow path along with three cone-shaped receiving ports arranged in a cloverleaf pattern around the center post. The die has three curved slots on the output side of the die which are in fluid communication with the cone-shaped receiving ports. At the distal end of each of these slots is a semi-circular tip. The tip has a diameter larger than the width of its associated slot. Further, the tip is located at the apex of a cone-shaped receiving port with which it is in fluid communication, thus providing for the highest flow velocity of the extrudate through the tip. The resultant flow profile produces the consistent spiral shape of the snack product produced by the die design described.
