One of the essential functions of a mixer is to achieve homogeneous mixing powders and liquids. In this study, a 3D motion mixer with a sealed vessel without stirring blades was used. However, the flow state of powders and liquids in a sealed vessel is unknown, and it is generally necessary to open the vessel to examine the mixing state to evaluate it. Previous studies have demonstrated that non-contact dispersion methods using silica sand can yield results comparable to those obtained through direct evaluation techniques. In the present study, we focused on differences in powder properties and conducted non-contact dispersion evaluations using wheat flour (strong flour), which has particle sizes closely matching those of silica sand.
