An outstanding separator system for the biotech and pharmaceutical industries. The Alfa Laval BTPX range bridges the gap between laboratory and commercial production.
The BTPX 710 module is based on the solids-ejecting centrifuge BTXP 710SGD-34CDP in claridier execution. It is equipped with a double axial spindle seal and timer-trigggered solid discharge. It is used for removing suspended solids with particle sizes from appraximately 0.5 to 500 µm from a liquid having a lower specific gravity than the solids. The solids content in the feed is normally in the range of 0.1-10% by volume.
The main applications are bacteria, rDNA products, enzymes, growth factors, cell cultures and vaccines.
The BTPX 710 has a timer-triggered partial discharge system, meaning that only part of the bowl content is emptied during discharge. The discharge takes place at full speed without any interruption of the feed.
The inlet of the separator is equipped with wing type distributor or a low shear disk inlet, which enables separation of products with foaming tendency or high sensitivity to shear. The flanged motor is direct coupled to the drive system. The drive system is splash lubricated without any need for an external lubrication circuit.
All product wetted surfaces are in high grade stainless steel with a standard surface finish of less then 1.2 micron Ra. Finer finish is available on demand. The bowl casing, cyclone and cooling jackets are pressured rated to 3 bar. The Separatorcan be steam sterilised up to 1300. TThe separator can be mounted in a fully contuined system with no risk for product or environmental contamination. The built-in paring disc for the liquid phase eliminates the need for an external pump. The machine is equipped with nozzles for flushing above the bowl and in the sediment oulet.
All liquid-wetted parts are in high-grade stainless steel and liquid-wetted rubber gaskets in FDA approved EPDM. The centrifuge is available with main connections as sanitary flanges and all other utility connections clamp type. The centrifuge can be equipped with sensors for monitoring vibration level, and a cover switch to be used for preventing the motor from being started unless the centrifuge top part has been properly mounted. The centrifuge is equipped with anchoring feet and vibration dampers.
