Inline Mixers

Not every mixing task belongs in a vessel. In continuous processes, dosing loops or rapid heating, mixing has to take place directly in the pipe. Two designs cover this: the static mixer SM, which uses the flow energy of the medium, and the dynamic tubular mixer, which uses a motor to introduce mixing energy independently of the flow rate.

Two designs

Passive or active. Depending on the mixing task.

Static mixer SM

  • Uses the flow energy of the medium
  • No moving parts, no shaft seal
  • Maintenance-free, no spare parts
  • Reproducible mixing result

Dynamic tubular mixer

  • Motor driven
  • Shear forces independent of flow rate
  • For emulsions and dispersions
  • Lower pressure drop than a static mixer

Static mixer SM

No moving parts. No seal.

In the bio-m® SM, fixed mixing elements repeatedly divide the product stream and recombine it. The mixing energy comes from the flow alone. Unlike a vessel, where part of the medium circulates longer than the rest, in the static mixer the entire product passes through the same mixing path.

  • No mechanical seal, no wearing parts
  • Mixing elements housed in a sanitary tube
  • Surface Ra < 0.8 µm (standard) or Ra < 0.6 µm (electropolished)
  • Mixing element removable for inspection
  • Cleaning in place (CIP) without shadow zones

SM options

Matched to line length and viscosity.

L1 with 6, L2 with 12 elementsMixing elements

For simple blending, 6 elements are sufficient. For difficult viscosities, 12 elements ensure full homogeneity.

For dosing small additivesIntegrated injector

A nozzle introduces the additive, for example for pH adjustment or colouring, directly upstream of the first element into the centre of the flow. This improves blending and saves pipe length.

From 316L to PTFE-linedMaterials

316L is the standard. For aggressive media, 2.4602 and titanium are available, and fully PTFE-lined units for aggressive acids.

Dynamic tubular mixer

Shear and flow rate, set independently.

In a static mixer, mixing energy depends on how fast you pump. The dynamic tubular mixer decouples the two: at a low flow rate the mixer can run at high speed and create intense shear. This is needed for stable oil-in-water emulsions or for breaking down agglomerates.

  • Mixing energy set by speed, independent of flow rate
  • The moving element actively conveys the fluid; pressure drop is significantly lower than with a static mixer
  • Shaft sealing with EPDM lip seal or mechanical seal, depending on pressure and sterility requirements
  • Optional double jacket for heating or cooling during mixing, for example in crystallisation or pasteurisation loops
