FEUX
The Alfa Laval FEUX separator incorporates a unique combination of design features to ensure optimum separation and concentration efficiency in industrial fermentation applications.
The FEUX separators take advantage of the fact that the slurry of concentrated solids is pseudo-plastic and flows easily in the bowl against the centrifugal force. This means that the recovered solids can be obtained with a low demand on energy in a closed system under pressure. Therefore, the hygienic conditions are very good, further improved by a full-speed CIP procedure.
Unique Vortex nozzle design
Like the BTUX and MBUX separator models, the FEUX separator bowl is equipped with Alfa Laval´s unique vortex nozzles, which offers performance unmatched by conventional nozzle centrifuges. With the self regulating vortex nozzles the concentration of discharged solids phase can be kept at a high and even level irrespective of fluctuations in the feed flow or feed concentration. The centrifuge can thus be operated closer to the clogging point without increasing the risk of clogging.
The FEUX separator is designed for automatic ejection of washed-out solids during the cleaning cycle, which makes it particularly suitable for process lines equipped with automated cleaning-in-place (CIP).
A complete range
The FEUX is available in different sizes covering a wide range of process demands, from medium up to large scale production.
Benefits
- Self-regulating vortex nozzles for optimal concentrate dryness and minimum clogging risk
- Hygienic design

Learn more about FEUX nozzle centrifuges
FEUX separators are designed to allow solids to flow easily in the bowl, even against centrifugal force. This means low energy consumption within a closed, pressurized, and hygienic system.
Inside the disc-type bowl, solids pass through concentrate tubes and vortex nozzles, and are discharged under pressure via a paring tube. The clarified liquid moves toward the center and is also discharged under pressure. Solids can be automatically ejected during cleaning cycles, making the system ideal for CIP lines.
Self-regulating vortex nozzles
Alfa Laval’s vortex nozzles automatically adjust to variations in feed flow and solids content, maintaining a consistent solids concentration. The inlet and outlet pressures are comparable to standard pressure drops and remain stable, regardless of concentrate viscosity.
Concentrate enters tangentially, spins in the nozzle chamber, and exits through a central outlet. This design allows operation close to the clogging point without increasing blockage risk.
Complete system
FEUX units come in various sizes and can include the separator, motor, solids cyclone, switchgear and starter, control panel, valve cluster, flow meter, sight glasses, flexible connections, and other auxiliary equipment.
