Vacuum Planetary Deaeration Defoaming Mixer – High-Capacity, Bubble-Free Production Solution

By SUBIT Technology – Shenzhen, China
1. Why This Mixer Matters
For high-viscosity materials (silver paste, silicone, epoxy, battery slurries), even microscopic bubbles cause pinholes, voids, and poor adhesion – directly reducing yield. Traditional blade mixers contaminate, damage shear-sensitive particles, and cannot remove sub-micron bubbles.
The 4000ml x 2 Cups Vacuum Planetary Deaeration Defoaming Mixer solves these problems in one production-ready machine:
Capacity – up to 10 kg per batch (5 kg × 2 cups)
Viscosity – handles up to 300,000 cps
Cycle time – complete mixing + defoaming in minutes
2. How It Works
Non-contact, bladeless planetary motion – each cup revolves and rotates simultaneously, generating intense convective flow without mechanical contact.
Integrated vacuum system (–0.098 MPa) – expands and collapses bubbles during mixing, removing even invisible microbubbles.
Programmable control – 5 programs × 5 steps, ensuring batch-to-batch repeatability.
3. Core Specifications (Model SBT-VTP4000S)

Supports custom adapters for 150ml–4000ml cups.
4. Key Applications
Electronics & Semiconductors – LED/OLED phosphor, conductive pastes, underfill, encapsulation resins
New Energy – lithium battery electrode slurries, solar cell pastes
Medical & Biomedical – adhesives, collagen hydrogels, bioactive materials
Advanced Materials – nanomaterials (graphene, CNTs, silver nanowires), fine chemicals, cosmetics
In all cases, the mixer eliminates bubbles >95% while preserving particle integrity.
5. Why Choose a Vacuum Planetary Mixer Over Traditional Methods?

6. 5 Critical Buying Criteria
When evaluating a 4000ml-class defoaming mixer, focus on:
Transmission precision – stable gearing ensures uniform mixing.
Vacuum system – stable ≥ –0.095 MPa, fast evacuation, low leakage rate.
Control intelligence – PLC touchscreen with recipe storage for repeatability.
Temperature rise – minimal heat generation (critical for heat‑sensitive materials).
Build & safety – stainless steel construction, interlocks, overload protection.
