An apparatus (10) for forming a single extrudable food stream such as a cooked cereal dough into a plurality of differently colored and/or flavored dough streams is disclosed including an extruder (12) having screw augers (15) for advancing a plastic food mass, a head or manifold (118) for dividing
An apparatus (10) for forming a single extrudable food stream such as a cooked cereal dough into a plurality of differently colored and/or flavored dough streams is disclosed including an extruder (12) having screw augers (15) for advancing a plastic food mass, a head or manifold (118) for dividing the plastic food mass into a plurality of substreams each in turn in fluid communication with a plurality of sub-divided dough passageways, and a die head (30) having a plurality of die ports (40). Each subpassage is separately supplied an additive and has disposed therein a multiplicity of in-line static mixer elements (59) to admix the additive into the substreams of the plastic food mass before passage through the die ports (40). In a preferred form, first and second substreams are intermixed in a non-homogenous manner before reaching the exit ports (40). The extrudates are severed into individual pieces (158) by a rotary cutter (36).

1. An apparatus for producing a non-homogenously mixed extrudate, comprising, in combination: means for supplying a first product mass substream disposed within a first subpassageway having an interior surface and a second mass substream disposed within a second subpassageway having an interior surface; an interconnecting passage in communication with the first and second subpassageways; an exit port in communication with the interconnecting passage; a transition element including an upstream face, a downstream face, and a peripheral edge extending between the upstream and downstream faces, with the peripheral edge corresponding to and for slideable receipt in the interconnecting passage; first and second sets of subpassages extending between the upstream and downstream faces of the transition element; first and second channels extending from the upstream face towards but spaced from the downstream face, with the first channel being in communication with the first subpassageway and the first set of subpassages but not with the second subpassageway and the second set of subpassages, with the second channel being in communication with the second subpassageway and the second set of subpassages but not in communication with the first subpassageway and the first set of subpassages; and a static mixer located in the interconnecting passage intermediate the exit port and the downstream face of the transition element. 2. The apparatus of claim 1 wherein the interconnecting passage includes a shoulder, with the first and second subpassageways extending through a transition plate, with the transition element and the static mixer sandwiched between the shoulder in the interconnecting passage and the transition plate. 3. The apparatus of claim 1 wherein each of the first and second sets of subpassages include a plurality of subpassages. 4. The apparatus of claim 3 wherein the first and second sets of subpassages are symmetrical to a diameter of the transition element extending between axial centers of the first and second subpassageways. 5. The apparatus of claim 4 wherein each of the plurality of subpassages are arranged in a series parallel to the diameter. 6. The apparatus of claim 5 wherein the channels extend parallel to the upstream and downstream faces of the transition element and the first and second sets of subpassages extend parallel to the peripheral edge of the transition element. 7. The apparatus of claim 5 wherein the plurality of subpassages includes a last subpassage at a greatest spacing from the peripheral edge of the transition element, with the last subpassage including a first portion extending from the downstream face towards but spaced from the upstream face, with the first portion having oval cross sections parallel to the upstream and downstream faces, with the last subpassage including a second portion extending from the upstream face to the downstream face, with the second portion having cross sections parallel to the upstream and downstream faces smaller than the oval cross sections of the first portion, with the second portion intersecting with the first portion. 8. The apparatus of claim 7 wherein the cross sections of the second portion are eye-shaped, with the first and second portions having a coextensive end surface. 9. The apparatus of claim 7 wherein each of the first and second channels includes a first section and a second section, with the first section including first and second, spaced, parallel walls parallel to the diameter and extending from the peripheral edge, with the second section including a semi-cylindrical wall extending between the first and second walls of the first section, with the second portion of the last subpassage located within the second section. 10. The apparatus of claim 9 further comprising, in combination: third and fourth channels extending from the upstream face towards but spaced from the downstream face and spaced from the first and second channels, with the first and second channels located intermediate the third and fourth channels, with the third and fourth channels being J-shaped parallel to the upstream and downstream faces and intersecting with the peripheral edge; and third and fourth sets of subpassages extending between the upstream and downstream faces, with the third channel being in communication with the first subpassageway and the third set of subpassages but not with the second subpassageway and the first, second, and fourth subpassages, with the fourth channel being in communication with the second subpassageway and the fourth set of subpassages but not in communication with the first subpassageway and the first, second and third sets of subpassages. 11. The apparatus of claim 10 further comprising, in combination: an arcuate channel in communication with the interconnecting passage, with the arcuate channel being arcuate in a plane parallel to but spaced from the upstream and downstream faces of the transition element, with the exit port comprising a plurality of die ports each in fluid communication with the arcuate channel. 12. The apparatus of claim 4 wherein each of the plurality of subpassages is arranged in first and second series parallel to each other and a diameter. 13. The apparatus of claim 1 further comprising, in combination: an arcuate channel in communication with the interconnecting passage, with the arcuate channel being arcuate in a plane parallel to but spaced from the upstream and downstream faces of the transition element, with the exit port comprising a plurality of die ports each in fluid communication with the arcuate channel.
