Soft Mixer

A NEW INDUSTRIAL MIXER BLADE-FREE


CONTEXT

Most of the available mixers have propellers or blades of various shapes and size. But for specific use in pharmaceutical, food & beverage or chemical industry, these blades induce shear and/or cavitation issues, which may damage cells or molecules. Furthermore, the blade rotation leads to a boundary layer on the edge of the container, which reduces the mixing quality.

HOW IT WORKS

‘Soft Mixer’ is a mixer without blade or propeller. Inspired by works on Earth precession, this device is a simple cylinder set in rotation, with specific dimensions and tilted from the vertical. This specific configuration induces a resonance in the fluid, which leads to a complex and turbulent intern flow.

 

KEY BENEFITS

  • Mixing rate improved within the fluid as well as at the free surface for gaseous exchanges
  • Shearing is drastically reduced due to the absence of blade
  • Simplicity : the dimensions can be adapted very quickly to obtain various volumes, with no assembly, contamination or cleaning issue.

 

DEVELOPMENT STATUS

  • Proof of concept
  • Development works in progress

 

APPLICATIONS

  • Mixing Processes
  • Tanks, fermenters, bioreactors
  • Agitators, propellers, impellers
