Vacuum Planetary Deaeration Defoaming Mixer: The Ultimate Solution for Bubble-Free Precision Mixing

In electronics manufacturing, new energy production, and biomedical engineering, even microscopic bubbles can be the difference between a pass and a reject. Traditional mixing methods—mechanical stirring or simple vacuum extraction—often leave behind micro-bubbles that cause pinholes, structural weaknesses, and inconsistent product performance.
Enter the vacuum planetary deaeration defoaming mixer: a non-contact, blade-free system that combines planetary motion with high-vacuum degassing to deliver uniform mixing and complete bubble elimination in minutes

How It Works

The mixer operates on a dual-axis principle: revolution (the container orbits around a central axis) and rotation (the container spins on its own axis). This compound motion generates powerful centrifugal forces—up to hundreds of times the force of gravity—that push materials outward and downward, forcing bubbles to rise to the surface.
For high-viscosity materials where bubbles rise slowly, the vacuum function steps in. By creating a high-vacuum environment (down to 0.1 kPa absolute pressure), bubbles expand rapidly under reduced pressure and are destroyed. The shearing force from rotation then eliminates any remaining bubbles on the liquid surface. This dual mechanism achieves a deaeration rate of over 99.5% —removing both surface and internal bubbles.
