Product overviewA vacuum sigma mixer is a sigma-type industrial mixer fitted with a sealed, evacuable chamber and a vacuum system to mix, knead and process materials under reduced pressure. It is designed to remove entrapped air and gases, reduce oxidation risk and ensure consistent dispersion for high-viscosity and heat-sensitive formulations.
Key features- Vacuum chamber: sealed mixing chamber designed to be evacuated and to withstand vacuum conditions.
- Vacuum system: integrated vacuum pump or connection for external vacuum; sizing depends on application.
- Mechanical seals: tight seals around shafts and openings to preserve vacuum integrity.
- Jacketed chamber (optional): allows temperature control via circulation of heating or cooling fluids.
Applications- Deaeration: removal of air and entrapped gases for adhesives, sealants and electronic compounds.
- Heat-sensitive materials: lower boiling points under vacuum enable gentler mixing of thermosensitive ingredients.
- High-viscosity compounds: improved kneading and dispersion for rubbers, pastes and heavy polymers.
- Oxidation-sensitive products: reduced oxygen exposure for pharmaceutical, cosmetic and food formulations.
Advantages- Improved product homogeneity and reduced internal voids.
- Prevention of oxidation and degradation of sensitive components.
- Better control of processing environment and shorter cycle times in many applications.
- Optional temperature control for processes requiring heating or cooling.
