Abstract

Almost stirring devices used blades to stir materials, by the existence of which some efforts were necessary to wash stirring tanks or to exchange materials. So the purpose of this study was to develop devices to stir materials by Coriolis force with no blade. A cylinder rotating around horizontal axis was put on the turntable rotating around vertical axis. The vortex in the rotating cylinder was inclined in the directions upper right or lower right by the effects of Coriolis force. As the speed of turntable was increased, the vortex was collapsed. The phenomena were expected applicable to stirring process and washing process. To examine the effects of stirring process, two types of material were used, that is, undiluted solution of the aqueous paint and washing paste (polyvinyl alcohol). As a result, successful conditions of stirring process became clear with the relations among rotation numbers of capsule, rotation numbers of turntable and diameters of capsule.
