Abstract
Corn meal was extruded in a twin-screw extruder to study effects of on e and two reverse-screw elements on conversion at extrusion temperatur es < 60 degrees C. Significant conversion was observed across the reve rse-screw elements. The conversion was due to shear alone, since therm al effect was negligible at these low temperatures. Encompassing the r everse-screw elements were four visually distinct zones characterized by the state of the material.
