Abstract

Degerminated yellow corn meal was extruded with a Werner and Pfleiderer ZSK-30 corotating twin-screw extruder under a wide range of processing conditions. The effects of process variables on mean residence time were examined by changing one variable at a time, as well as by applying statistical models to analyze situations when two or more process variables were changing. The most significant process variables affecting mean residence time were screw speed followed by throughput. Moisture content had only borderline effect, while die pressure and die temperature had no significant effect.
