A simulation apparatus, and program, for screw extruder volatilization, being capable of practical simulation of the volatilization process of screw extruder. There is provided an extruder simulation system capable of simulation of volatilization condition through computing of intra-extruder resin temperature, pressure, stay time, filling ratio, torque, power, solid-phase occupancy and volatile contents concentration as a distribution in the direction of extruder axle from extruder apparatus structure, operating conditions and resin properties, which extruder simulation system includes means for arithmetical operation for the process of gradual decline of volatile contents concentration of the resin by volatilization by vent cylinder.

L'invention concerne un appareil de simulation, et un programme, pour volatilisation par extrudeuse à vis, capable de réaliser la simulation du processus de volatilisation par extrudeuse à vis. L'invention concerne un système de simulation par extrudeuse capable de simuler la condition de volatilisation par calcul de la température de résine à l'intérieur de l'extrudeuse, la pression, le temps de séjour, le rapport de remplissage, le couple, la puissance, l'occupation en phase solide et la concentration en teneurs volatiles comme distribution dans la direction de l'essieu d'extrudeuse à partir de la structure d'appareil à extrudeuse, les conditions d'exploitation et les propriétés de résine, lequel système de simulation d'extrudeuse comporte des moyens de fonctionnement arithmétique pour le processus de déclin progressif de la concentration en teneurs volatiles de la résine par volatilisation par cylindre à évent.
