  • Publication number: 20030008032
    Abstract: A multilane extruder system is provided for forming a pliable mass such as a food dough into a plurality of substantially identical elongated extruded strips, and for depositing these strips onto a conveyor for further processing such as cutting into individual strips of selected length. The extruder system comprises an extruder manifold defining a plurality of flow channels having a substantially identical cross sectional size, shape, and length. Each flow channel includes a first segment extending radially outwardly from a central plenum chamber, and connecting with a second segment extending generally radially inwardly and terminating in an extrusion die port of selected shape. The second channel segments are oriented each at a selected individual angle relative to the radial direction for delivering the extruded strips onto the underlying conveyor in a substantially uniformly and closely spaced relation.
