Operating Parameters’ Influence on the Specific Volume of Extrusion Puffed Food

Chi Wu Bu

Abstract

Twin-screw extruder is the main equipment for puffed food processing. Corn powder as the main raw material, barrel temperature, screw speed and feed rate of the extruder as the independent variables, specific volume of the extrusion product as the objective function, experiment has been carried out base on factorial design method. How the independent variables influence the objective function has been analyzed. Values of the operating parameters to get optimal specific volume has been gained.
