Method of making puffed dough pieces of varying configuration

摘要

An assortment of extrusion-puffed dough shapes of varying configurations is produced from a single extruding die assembly by mounting said assembly on a cooker extruder expander adapted to produce a gelatinized cereal dough mass and discharge same as individual moieties sequentially through a plurality of orifices in a backup zone and an extruding zone, the flow rates of said moieties being varied in passage in relationship to the flow characteristics of respective shaping dies by coordinating flow characteristics in respective backup zones so as to cause individual dough masses upon issuance from the face of the assorted extruding die orifices to have extrudates move at comparable linear speed whereby said moieties can be consecutively subdivided by a rotating knife assembly and uniformly puffed, flow coordination being evenly modulated by a substantial buffering zone in a dead space in said cooker.
