What Is a Bottom Homogenizer Vacuum Emulsifying Mixer and How Does It Work?
A bottom homogenizer vacuum emulsifying mixer is a compact yet powerful emulsifying machine designed for R&D laboratories, pilot plants, and small-batch production. The equipment features a unique bottom-mounted homogenizer positioned at the lowest point of the vessel, allowing materials to flow naturally into the shear zone under the influence of gravity . For high-viscosity, highly thixotropic pastes, this design is more effective at achieving fine particle sizes than top-mounted homogenizers, typically achieving D90 ≤ 5 microns or even nanoscale particles.
How It Works:
| Component | Function |
|---|---|
| Bottom-Mounted Homogenizer | Positioned at the vessel's lowest point; gravity-assisted flow into shear zone; achieves D90 ≤ 5 microns or nanoscale particles |
| Scraper Mixer | PTFE scraper blades sweep the wall of the tank to prevent residue buildup; speed adjustable 10-120 rpm |
| Vacuum System | Removes air bubbles during mixing under vacuum to prevent oxidation and ensure bubble-free products |
| Heating/Cooling System | Jacketed design with electric or steam heating (optional) and water cooling or mold temperature controller (optional) |
| 3-in-1 System | Complete system integrates main emulsifying pot with oil phase and water phase pots |
The Working Principle:
The complete system comprises three integrated vessels: the main emulsifying pot, the oil phase pot, and the water phase pot . Materials are placed into the premix oil phase and water phase tanks. After being heated and mixed separately, they are drawn into the emulsifying pot by a vacuum pump . The middle stirrer and Teflon scrapers sweep residues on the tank wall, making the materials wipe off and become a new interface constantly. The materials are then cut, compressed, and folded by blades to stir, mix, and run to the homogenizer . Through the strong cutting, impact, and turbulent current from the high-speed shear wheel and fixed cutting case, materials are cut in the interstices of the stator and rotor and turn into particles of 6nm-2um promptly . Because the tank works under vacuum, bubbles produced during vacuum mixing are taken away in time .
