Alfa Laval MBUX industrial centrifuges are designed for recovery of yeast and bacteria in pharmaceutical and probiotics applications. These pharmaceutical centrifuges are available in different sizes and require relatively little energy to recover concentrated solids. The concentrated biomass flows through a set of nozzles into the center of the centrifuge, where it is pumped out under pressure using a paring device. This closed configuration also enhances hygiene.
Experience the benefits of the MBUX , pharmaceutical centrifuges designed for efficient separation of yeast and bacteria
- High uniform concentration of discharged solids phase regardless of fluctuations in feed flow or concentration due to self-regulating vortex nozzles
- Less foaming – light and heavy phase are both discharged under pressure which simplifies installation (no pump systems) and improves hygiene
- No accumulation of packed solids – pockets in the bowl guide solids to the concentrate tubes making separation and CIP easy and effective
- Cost effective operation
- Efficient – bowl can be opened intermittently during production and/or cleaning cycle to eject solids while machine continues to run at full speed
The working principle of MBUX centrifuges
The Alfa Laval MBUX pharmaceutical centrifuges are available in a range of sizes to support diverse processing needs. It is equipped with Alfa Laval’s patented self-regulating vortex nozzles, which maintain a consistent discharge solids concentration—even when feed flow or solids content changes.
These nozzle separators operate based on the fluid’s viscosity and the rotational speed inside the vortex chamber, which together determine the pressure drop. The concentrate enters the nozzle chamber tangentially, creating a centrifugal whirl that exits through a central outlet. While the pressure drop at the inlet and outlet is mostly unaffected by viscosity, the pressure drop created by the internal vortex increases or decreases with the rotation speed.
Thanks to this design, the solids concentration remains consistently high. This allows the pharmaceutical centrifuge to operate closer to its clogging limit while still minimizing the risk of blockage. It offers a clear advantage over traditional yeast centrifuge systems, especially when handling shear-sensitive materials or variable feed compositions.
