Tianfeng TF-SFD-30m² Industrial Freeze Dryer

Overview

The Tianfeng TF-SFD-30m² Industrial Freeze Dryer is a cGMP-compliant, production-scale lyophilization system engineered for pharmaceutical, biotechnology, and fine chemical manufacturing environments. It operates on the principle of sublimation—first freezing the product at controlled low temperatures, then applying high vacuum to enable direct phase transition from ice to vapor without passing through the liquid state. This process preserves thermolabile compounds, structural integrity, and biological activity while achieving long-term stability and reduced microbial risk. Designed for batch processing of bulk parenterals, vaccines, diagnostics, sterile APIs, and cosmetic actives, the system delivers consistent drying kinetics across its 29.7 m² shelf area, supporting up to 133,600 vials (Φ16 mm) or 68,300 vials (Φ22 mm), with a maximum load capacity of 590 L of aqueous solution per cycle.

Key Features

• Stainless steel chamber (AISI 304) with fully polished, radius-rounded internal geometry to eliminate dead zones and facilitate CIP/SIP validation;
• Thirteen + one temperature-controlled shelves (1515 mm × 1520 mm each), spaced at 100 mm intervals, fabricated via uniform thermal stress-relief heating to ensure ≤±0.5 °C surface flatness tolerance;
• Shelf temperature range: −55 °C to +70 °C, regulated via low-viscosity silicone oil circulation for exceptional thermal uniformity—even at cryogenic setpoints;
• High-efficiency condenser operating at −75 °C, rated for 640 kg ice capture over 24 hours under continuous operation;
• Ultimate vacuum capability of 2.7 Pa, supported by a dual-stage vacuum pump train and verified leak rate ≤0.1 Pa·m³/s;
• Integrated PLC-based control system compliant with IEC 61131-3 standards; supports recipe storage, real-time parameter logging, alarm history, and automated cycle execution;
• Full compliance with ISO 9001:2015 quality management systems and design alignment with EU Annex 1, FDA 21 CFR Part 11 (audit trail, electronic signature, data integrity), and WHO TRS 986 requirements;
• Optional IQ/OQ/PQ documentation packages available upon request, including 3Q validation protocols, calibration certificates, and FAT/SAT reports.

Sample Compatibility & Compliance

The TF-SFD-30m² accommodates diverse sample formats—including serum vials, trays, ampoules, and bulk containers—across pharmaceutical, diagnostic, and cosmetic applications. Its chamber geometry and shelf layout support both stoppered vial drying and bulk tray drying with uniform heat transfer profiles. All wetted surfaces meet ASME BPE-2021 surface finish specifications (Ra ≤ 0.4 µm). The system conforms to GMP-grade construction standards per ISPE Baseline Guide Volume 4 (Sterile Manufacturing) and supports validation against ASTM F2338 (leak testing), ISO 13408-1 (sterile processing), and USP (lyophilization process validation). Materials of construction are non-reactive, non-leaching, and compatible with common sterilants (e.g., hydrogen peroxide vapor, saturated steam).

Software & Data Management

The embedded HMI interface provides intuitive access to all operational parameters, historical trends, and alarm logs. Process data—including shelf temperature, chamber pressure, condenser temperature, and time-stamped events—is automatically archived in CSV and PDF formats with configurable retention policies. The system implements role-based user access control (operator, engineer, administrator), full electronic audit trail per 21 CFR Part 11, and encrypted data export. Optional SCADA integration enables centralized monitoring via OPC UA or Modbus TCP. All software modules undergo periodic cybersecurity assessment in accordance with IEC 62443-3-3 and NIST SP 800-82 guidelines.

Applications

• Pharmaceutical manufacturing: Lyophilization of monoclonal antibodies, recombinant proteins, live attenuated vaccines, and sterile small-molecule formulations;
• Biologics R&D and scale-up: Process development support from lab-scale to commercial batches;
• Cosmetic active ingredient stabilization: Preservation of peptides, growth factors, and enzymatic complexes without denaturation;
• Diagnostic reagent production: Drying of ELISA kits, PCR master mixes, and lateral flow assay components;
• Fine chemical synthesis: Dehydration of catalysts, chiral intermediates, and hygroscopic specialty chemicals;
• Academic and contract manufacturing organizations (CMOs): GMP-aligned infrastructure for clinical trial material production.
