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) IN A MAIN PASSAGEWAY (14) FOR ADVANCING A PLASTIC FOOD MASS, A HEAD OR MANIFOLD (18) FOR DIVIDING THE PLASTIC FOOD MASS INTO A PLURALITY OF SUBSTREAMS SUCH AS A BRANCHING PASSAGEWAY SECTION IN FLUID COMMUNICATION WITH A PLURALITY OF SUB-DIVIDED DOUGH PASSAGEWAYS, AND A DIE HEAD (30) HAVING A PLURALITY OF DIE PORTS (40) FOR EACH SUBPASSAGEWAY. 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, A PORTION OF THE FOOD MASS IS BLED FROM A FIRST SUBSTREAM AND FED TO THE EXIT PORTS (40) OF A SECOND SUBSTEAM TO CREATE AN EXTRUDATE INCLUDING ZONES OF DISTINCT FOOD MASS. THE EXTRUDATES ARE SEVERED INTO INDIVIDUAL PIECES (41, 158) BY A ROTARY CUTTER (36). MOST ILLUSTRATIVE DRAWING IS (FIGURE 6).
