Abstract

Container filling is a critical unit operation that is far from being sufficiently understood. No models or methods published can be used to study or simulate the feed shoe filling process or pressure (mass) increase for real-world problems involving a large number of 3D particles of various shapes and sizes. In order to further the understanding of the container filling process, models were developed and verified to simulate the pressure ratio increase for the entire filling process by using the second generation pressure deposition tester (PDT-II). The results indicated that the entire pressure increase profile could be divided into 10 stages, and all the stages could be simulated by a rate equation, based on the data collected and the physics of the filling process. Based on the powder deposition characteristics, the overall rate equation for all the ten stages was: dP p/dT = aP pF(T) + β. Furthermore, for stage 1 with the largest amount of powder deposited, the rate equation was dP p/dT = aP p/( e bT -1). The average, maximum, and minimum values of the root mean square error (RMSE) for a total of 17 locations in the vicinity of the geometric center (r≤4 mm) of the middle (center) container were 0.13, 0.19, and 0.11, respectively, and the average relative difference (ARD) values were 0.07, 0.09, and 0.06, respectively.
