Vacuum planetary degassing and defoaming mixer: achieves bubble-free and uniform mixing

For manufacturers in LED packaging, electronic components, new energy materials and fine chemical sectors, mixing quality directly determines product yield and performance. Trapped air bubbles, uneven particle dispersion and material contamination are common pain points that lead to defective products and wasted costs.
As a professional industrial mixing equipment manufacturer based in Shenzhen, China, Subit presents the SBT-VTP20000S Vacuum Planetary Deaeration Defoaming Mixer — an all-in-one system that completes mixing, dispersion and deep degassing in a single non-contact process, delivering consistent, high-purity material preparation for high-end industries.
Working Principle: Planetary Motion + Vacuum Degassing
This mixer relies on a dual planetary mechanism paired with a controlled vacuum environment to achieve efficient, thorough deaeration and homogeneous blending:
Dual-axis planetary mixing: When materials are loaded into the processing cups, the cups spin on their own axis while revolving around a central axis. This synchronized motion generates strong forced convection inside the material, fully blending multiple components and distributing particles evenly across the mixture.
Real-time vacuum degassing: The entire mixing chamber operates under vacuum, actively extracting trapped air from the material throughout the mixing cycle.
Shear-enhanced dispersion: Sharp changes in flow velocity and direction between the material bulk and container wall create powerful shearing forces. These forces refine droplets and particles, improve dispersibility, and break large bubbles into micro-bubbles for more complete degassing.
The fully non-contact design also eliminates cross-contamination and preserves the integrity of sensitive functional materials.
