Separation system for Pharmaceutical and Biotechnical applications
BTAX 215
The BTAX centrifuge is specially designed for biotechnical
processes such as cell harvesting, broth clarification and
the separation of cell debris. The centrifuge has a very high
separation efficiency and can be installed in a closed system.
To ensure cleanliness, the BTAX can be heat pasteurised to
100oC.
Available models
The BTAX centrifuge is available in four versions
• BTAX 215S-31 CEP
Paring disc version.
• BTAX 215S-31 CEFP
Paring disc version, explosion protected.
• BTAX 215H-31 CEP
Hermetic version.
• BTAX 215H-31 CEFP
Hermetic version, explosion protected.
All BTAX models are gastight. The complete system can be
supplied in an explosion-protected version when required.
Throughput capacity
Actual throughput is in the range of 0-12 m3/h depending on
paring disc size and design, as well as on the amount and
type of solids in the feed, temperature, viscosity, required
degree of clarification etc. Max hydraulic capacity of disc
stack is much higher.
Efficient solids ejection
During separation, solids collect in pockets recessed in
the bowl wall which avoids undesirable solids build-up,
and minimizes disturbances during solids ejection. The
pneumatically operated solids-ejecting system ensures fast
and efficient discharges resulting in a clean bowl.
Axial discharge channels lead from the solids pockets to
valves, which are held closed by a spring loaded valve slide.
To eject solids from the bowl during operation the slide is
lowered momentarily by a very short injection of compressed
air or gas through the hollow bowl spindle. This opens the
valves and the solids are ejected.
High separation efficiency
The high speed of the bowl creates a peripheral centrifugal
acceleration of 12,000 gravities. This gives the BTAX an
extremely high separation efficiency that can capture particles
down to 0.1 ì in diameter.
Large solids space
Long periods between ejections is possible thanks to the large
(14 l) solids space, which results in better separation and drier
solids.
Paring disc design
In this version the clarified liquid is continuously discharged
under pressure by a paring disc, which is a stationary impeller
that converts the rotational energy of the liquid into pressure.
With the paring disc design there is no need for a downstream
pump.
Hermetic inlet and outlet
The bowl is always completely filled with liquid in the hermetic
version. This eliminates the risk for oxidation and airborne
infections and ensures gentle treatment of the product.
