Design Parameters and Conveying Characteristics of Twin Screw Extruder

2축(軸) 압출기(押出機)의 설계요인(設計要因) 및 이송량(移送量)에 관한 분석(分析)

This research was conducted to determine a preliminary design parameters for the development of twin screw extruder using Booy's screw design method, and to analyze a extrusion process using Janssen's mathematical flow model. In processing process, the experimental mass flow rates of com flour and wheat flour were almost the same as theoretical values corrected by correction factors of 0.95 and 0.6 respectively. It was appeared that the mathematical model would be suitable to predict the conveying capacity.
