Reason why high-viscosity materials can be agitated without agitator blades：
The planetary centrifugal mixer is a device that can agitate materials without using agitator blades and deaerate simultaneously.
There are three important factors to realize this.
(1) Revolution: Moves the material away from the center with centrifugal force.
(2) Rotation: Rotation of the container causes flow of the material (rotation and shearing).
(3) 45 degrees: Tilting the rotation axis by 45 degrees results in three-dimensional flow.Furthermore, the flow velocity (direction) changes suddenly between the liquid surface and the container wall, causing complicated flow and strong shearing force. This shearing force makes droplets and particles smaller and increases their dispersibility. At the same time, air bubbles are also dispersed finely.
As a result, it is possible to uniformly agitate even high-viscosity materials in a short time without using agitator blades.
