The effect of process variables on the residence time distributions of cereals in an intermeshing counter-rotating twin-screw extmder was measured using a red dye tracer. The tracer concentration was determined following the method of Bounie (1988) with some modifications. Among the extrusion variables studied, changes in feed moisture, barrel temperature, and screw speed affected the residence time. The flow behavior was near plug flow. None of the extrusion variables had any significant effect on the degree of fill and the degree of backmixing in the extruder.(Download PDF) (Export to EndNotes)
