  • 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.

  • Patent number: 8641396
    Abstract: Foil extrusion lines use spiral distributors for producing a melt which is as homogeneous as possible during operation. The spiral distributors are mostly available as cylindrical or conical axial spiral distributors or as radial spiral distributors. The spiral distributors have spiral channels that run in a multiple spiral arrangement so that rather flat horizontal edges are formed precisely in initial sections and vertical edges are formed between the beginning of spiral channels and transition sections of adjacent spiral channels. The melt can easily adhere there. To accelerate the melt in critical areas, the course or the cross-section of the channels or the surface are modified.

  • Patent number: 8641397
    Abstract: A spiral distributor for a die head of a foil extrusion line has spiral channels provided with shortening sections in their backward area. As compared to a geometrical rule for a discontinuation of the spiral channels which is valid in a prior section of the spiral channels, this arrangement leads to a faster discontinuation of the spiral channels. The design of the backward area of the spiral channels does not affect the good overlaying effect of the front part of the spiral channels. As compared to the customary embodiment, the channels are thus equipped with a less profiled backward end which leads to a more cost-effective manufacture and to a lesser flow resistance.

  • Patent number: 8636497
    Abstract: The invention concerns an extruder screw for a screw extruder for plasticizing and/or transporting thermoplastic materials comprising at least one extruder cylinder, a material feed means and at least one extrudate discharge at the end of the extruder cylinder, that is remote from the material feed means. The extruder screw has a screw flight, wherein the extruder screw has at least one intake region and forms at least one transport and mixing region and provided in the transport and mixing region are means for shearing the extrudate. The extruder screw according to the invention is distinguished in that provided as means for shearing the extrudate there is provided at least one shearing land which extends over more than half the length of the extruder screw, over the periphery of the extruder screw, wherein the shearing land is in the nature of a screwthread in opposite relationship to the screw flight.
