Continuous Homogeneity
Passive Efficiency or Active Control
The Inline Philosophy. Not all mixing happens in a tank. For continuous processes, dosing loops, or rapid heating, mixing must occur directly in the pipe. Liquitec offers two distinct technologies to achieve homogeneity "on the fly".
- The Passive Path (bio-m® SM): A static mixing solution that utilizes the flow energy of the fluid itself. Zero moving parts, zero maintenance, and absolute reproducibility.
- The Active Path (bio-m® Dynamic): A motorized inline mixer for applications requiring defined shear forces independent of the flow rate. Ideal for emulsions and dispersions where mechanical energy is required to stabilize the product.
Advantages
The Right Energy for the Mix
The bio-m® SM relies on helical mixing elements to repeatedly divide and recombine the flow stream.
- Zero Maintenance: With no moving parts and no mechanical seals, the static mixer is the most reliable component in your line. It never leaks, never fails, and requires no spare parts.
- Hygienic Design: The mixing elements are housed in a sanitary tube with surface finishes of Ra < 0.8 µm (standard) or Ra < 0.6 µm (electropolished). The element can be easily removed for inspection, or cleaned in place (CIP) with no shadow zones.
-
Defined Residence Time: Unlike a tank where some fluid circulates longer than others, the static mixer ensures every drop of product experiences exactly the same mixing history.
Sometimes, flow energy isn't enough.
- Shear vs. Flow: In a static mixer, mixing energy depends on how fast you pump. In the bio-m® Dynamic, we decouple this. You can run a low flow rate but spin the mixer at high speed to create intense shear. This is critical for creating stable emulsions (oil/water) or breaking down agglomerates.
-
Low Pressure Drop: Because the dynamic element actively moves the fluid, it creates significantly less back-pressure than a static mixer, which acts as a flow restriction.
Options
The Inline Toolbox
Static Mixer Configuration (bio-m® SM)
We tailor the mixing intensity to your pipeline length and viscosity.
Mixing Elements
Available in 6-element (L1) or 12-element (L2) lengths. For simple blending, 6 elements suffice; for difficult viscosities, 12 elements ensure full homogeneity.
The "Pre-Mix" Trick (Injection)
For dosing small additives (e.g., pH adjustment or colors), we offer an Integrated Injector. This nozzle doses the additive directly upstream of the first element in the center of the flow, maximizing efficiency and saving pipe length.
Materials
From standard 316L (1.4435) to exotic alloys like Hastelloy C22 (2.4602), Titanium, or fully PTFE-lined units for aggressive acids.
Dynamic Mixer Options
Sealing Technology
Since the shaft enters the pipe, the seal is critical. We offer standard EPDM lip seals or advanced mechanical seals depending on the pressure and sterility requirements.
Temperature Control
Optional Double Jackets allow for heating or cooling directly during the mixing process, ideal for crystallization or pasteurization loops
Connections
Both series integrate seamlessly into your piping:
- DIN 11866 Welding Ends (Standard).
-
Tri-Clamp or Bio-Connect Flanges for rapid disassembly.
