Our continuous solid-liquid separation centrifuge is purpose-engineered for primary clarification and biomass harvesting of biopharmaceutical fermentation broth, delivering uninterrupted phase separation to isolate microbial cells, cell debris and insoluble impurities while preserving target product integrity in the supernatant. Conventional batch separation workflows introduce process discontinuity, variable shear exposure and yield volatility that compromise upstream throughput and downstream chromatography loading consistency. Optimised for fed-batch, perfusion and continuous fermentation campaigns, this platform maintains stable separation cut-points across fluctuating broth density, solids loading and feed viscosity, establishing a robust unit operation gate that protects critical quality attributes and streamlines seamless integration with subsequent capture and purification sequences.
The sanitary, hermetically sealed separation architecture adheres to ASME BPE, cGMP and global biomanufacturing regulatory expectations, incorporating low-shear feed acceleration, precision disc stack geometry and automated continuous solids ejection to minimise aeration, oxidative degradation and bioburden ingress. Fully integrated CIP/SIP-capable flow paths, USP Class VI wetted seals, surface-finished stainless steel construction and real-time process instrumentation enable closed-loop regulation of feed rate, differential pressure and separation efficiency. Process design is validated through computational fluid dynamic modelling to tune residence-time distribution and sedimentation kinetics, supporting consistent clarification performance across pilot, clinical and commercial production scales.
This continuous separation configuration unlocks measurable operational and economic advantages by eliminating periodic downtime for bowl unloading, reducing manual handling risks and maximising harvest yield under high-biomass fermentation conditions. Its modular skid-mounted layout supports flexible capacity scaling and easy insertion into both new greenfield lines and retrofitted existing bioprocess trains, compatible with stainless steel and hybrid single-use facility architectures. Stable clarified supernatant quality reduces fouling rates on depth filters and tangential flow filtration systems, extending consumable service life and lowering overall downstream purification cost-of-goods.
We deliver full lifecycle engineering and validation support covering process sizing, P&ID development, FAT/SAT execution, commissioning oversight and validation documentation aligned with regulatory inspection requirements. Our bioprocess team provides post-startup tuning, troubleshooting and operational training to stabilise separation performance under variable feed conditions. This turnkey separation package enables biopharma developers and manufacturers to implement a reliable, scalable harvest step that translates robust fermentation performance into consistent, high-quality feed streams for downstream purification.
