The VacuumMaster is developed for products with medium to high viscosities and is designed with a directly driven high shear mixer at the bottom and top-mounted agitator. The vacuum feature allows automatic handling of the powder dosing directly from big bags or silos. By means of vacuum, the powder is drawn into the mixer below liquid level and instantly wetted.
The powerful, high-shear mixer generates a controlled vortex in the tank. The combination of vortex and vacuum effectively separates air from the liquid and generates a perfect homogeneous dispersion within seconds.
The result is a highly stable and homogeneous, air- and lump-free product.
Depending on the selected options, the mixer can be used as a batch mixer or as an in-line mixer. For in-line mixing, a circulation loop is required.
The VacuumMaster is compact and perfectly optimised for energy-efficient high shear mixing, while also being virtually maintenance-free.
Process overview – VacuumMaster working as a batch mixer with recirculation
Applications
The VacuumMaster has been optimised for mixing a wide range of products, e.g.:
- Products for spray drying
- Soft drinks
- Ice cream
- Sugar solutions
- Pectin solutions
- Syrup
- Slurries
- Soups
- Recombined milk-based products
- Etc.
(The final product must be pumpable using a standard centrifugal pump – viscosity up to 2000 cP. For viscosity above 2000 cP, the ProcessMaster is required)
