Method and apparatus for producing a braided puff extrudate

摘要

A process and apparatus for the production of a braid shaped puffed extrudate. A tube or other peripheral containment vessel is placed at the exit end of an extruder die that produces two or more extrudate streams. A circular air stream is then introduced into the peripheral containment vessel downstream of the glass transition point, thereby causing the extrudate streams to braid together within the containment vessel.
