Study on 3D Motion Mixer with Sealed Container

Abstract

3D motion mixer is designed for mixing by rotating a sealed vessel without inserting any blades or other parts into the stirring tank, so that no foreign objects can be mixed inside the container during stirring. However, as the process and state of stirring of the sample inside the container was unknown, therefore, operating conditions such as rotation speed and filling rate were dependent on experience. In this study, a transparent container was used to reveal the flow state of the powder interface inside the rotating container. Spatial analysis methods were applied to the positional information in the recorded images of fluorescent particles distributed near the transparent vessel wall through visualization experiments using UV fluorescent particles to clear the stirring process and to evaluate the dispersion state.
