PROGRESSING CAVITY EXTRUDER

摘要

An extruder or dispenser assembly for dough-like material. A progressing cavity pump receives the material and delivers it to an extruder assembly or die. In a preferred embodiment, the output of the pump is separated into independent streams. Each stream may have a desired minor constituent (such as color and/or flavor) added with the streams being co-extruded, as desired. Static mixers may be employed to incorporate the minor constituents into each stream.
