Abstract
Ball milling is a crucial step in matcha powder processing. In this study, experimental and numerical simulation investigations on the mechanical and physical properties of matcha powder during processing were conducted. Based on the discrete element method (DEM), a scaling model was established to improve simulation efficiency. Furthermore, three typical models of matcha particles were established and the coefficients of rolling friction and static friction were calibrated which were 0.064 and 0.50 respectively. Above this, the correlation between the mechanical and physical properties of matcha powder was also investigated. The results suggest that the morphological characteristics of matcha powders showed a highly significant correlation with the collision velocity; the flowability of matcha particles exhibited a significant correlation with both the collision velocity and the number of collisions. Predictably, these findings may provide a reference for the selection of processing parameters during matcha processing and the optimal design of production equipment.
