Tianfeng TF-LYO-30 Pharmaceutical-Grade Production-Scale Freeze Dryer

Overview

The Tianfeng TF-LYO-30 is a pharmaceutical-grade, production-scale freeze dryer engineered for the reliable and reproducible lyophilization of active pharmaceutical ingredients (APIs), particularly peptide-based therapeutics requiring stringent thermal and structural integrity control. It operates on the fundamental principle of sublimation—removing water from frozen material under deep vacuum while maintaining product temperature below its eutectic point—to preserve biological activity, chemical stability, and physical morphology. Designed for integration into end-to-end API manufacturing lines, the TF-LYO-30 supports continuous batch processing of up to 300 kg per cycle across 29.99 m² of shelf area, with hydraulic stoppering capability for vial-based final dosage forms. Its rectangular chamber, constructed entirely from electropolished AISI 304 stainless steel with fully radiused internal corners and stress-relieved welded shelves, meets core design requirements of Annex 1 (EU GMP) and USP for sterile processing environments.

Key Features

• Robust chamber architecture featuring seamless, passivated AISI 304 construction with zero dead-leg geometry and full CIP/SIP compatibility
• High-precision shelf system with uniform thermal distribution achieved via low-viscosity silicone oil circulation and ±0.5 °C temperature control accuracy across −55 °C to +80 °C range
• Dual-stage refrigeration system incorporating Bitzer semi-hermetic compressors and a −75 °C cold trap capable of condensing up to 600 kg of ice within 24 hours
• Omron PLC-based control platform with validated HMI interface, supporting recipe management, real-time parameter logging, and alarm history with timestamped audit trails
• Hydraulic stoppering module integrated into the shelf stack, enabling in-situ sealing of 16 mm or 22 mm vials at process endpoint without chamber venting
• Full compliance with cGMP design principles: smooth internal welds, no crevices, traceable material certifications, and documented FAT/SAT protocols

Sample Compatibility & Compliance

The TF-LYO-30 accommodates a broad spectrum of thermolabile biopharmaceuticals—including synthetic peptides, recombinant proteins, oligonucleotides, and small-molecule APIs—with validated performance across vial formats (121,000 units @ Ø16 mm; 64,000 units @ Ø22 mm per batch). All wetted surfaces comply with ASME BPE-2023 surface finish standards (Ra ≤ 0.4 µm), and chamber integrity is verified per ISO 13485 and FDA 21 CFR Part 11 requirements for electronic records. The system supports full validation documentation packages (IQ/OQ/PQ), including mapping studies for shelf temperature uniformity (per ASTM F2697), vacuum leak rate testing (per ISO 20517), and condenser efficiency profiling. It conforms to ICH Q5C (stability of biotechnological products) and ICH Q8 (pharmaceutical development) frameworks for process understanding and control strategy implementation.

Software & Data Management

The embedded microprocessor control system provides deterministic sequencing of freeze-drying cycles—including pre-freezing, primary drying, and secondary drying phases—with programmable ramp rates, hold times, and pressure modulation. Data acquisition captures >20 critical parameters (shelf temperature, chamber pressure, condenser temp, vapor pressure, etc.) at 1-second intervals, stored locally on encrypted industrial SSD with redundant backup. All electronic records are time-stamped, user-authenticated, and support ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Optional 21 CFR Part 11 compliance modules include role-based access control, digital signatures, and immutable audit logs exportable in CSV or PDF/A format for regulatory submission.

Applications

• Lyophilization of peptide APIs requiring high conformational fidelity and minimal aggregation
• Stabilization of monoclonal antibodies and fusion proteins prior to fill-finish operations
• Processing of sterile raw materials for oncology, metabolic, and immunomodulatory drug products
• Scale-up from lab-scale (e.g., TF-LYO-0.5) to commercial batches under identical critical process parameters
• Supporting Quality-by-Design (QbD) initiatives through PAT-enabled cycle optimization and multivariate analysis

FAQ

Does the TF-LYO-30 support automated loading/unloading integration?
Yes—it is designed for seamless interfacing with upstream filling lines and downstream powder handling systems via standard SECS/GEM or Modbus TCP protocols.
Is the system qualified for use in classified cleanrooms (ISO 5/7)?
The base configuration meets ISO 8; optional HEPA-filtered air handling, laminar flow shielding, and isolator-compatible door interfaces enable ISO 5 integration.
Can process parameters be exported for regulatory filing (e.g., CMC sections)?
All cycle data—including raw sensor outputs, setpoints, alarms, and operator actions—is exportable in FDA-submission-ready formats with full metadata and digital signature support.
What validation support is provided prior to commissioning?
Tianfeng delivers comprehensive FAT documentation, IQ/OQ protocol execution support, and on-site PQ assistance with third-party certified engineers.
Is remote monitoring and troubleshooting available?
The system includes secure TLS-encrypted remote access capability (with customer-defined firewall rules) for real-time diagnostics and predictive maintenance alerts.
