Tianfeng TF-SFD-15m²E Pharmaceutical-Grade Freeze Dryer

Overview

The Tianfeng TF-SFD-15m²E is a pharmaceutical-grade, shelf-type production freeze dryer engineered for robust, repeatable lyophilization of heat-sensitive biologics, nutraceuticals, and peptide-based formulations. Utilizing the fundamental principles of sublimation under deep vacuum and controlled thermal input, this system enables primary drying of aqueous solutions at temperatures well below the eutectic point—preserving structural integrity, biological activity, and long-term stability of active pharmaceutical ingredients (APIs), functional proteins, and hydrolyzed peptides. Designed for GMP-compliant manufacturing environments, the TF-SFD-15m²E integrates process-critical engineering features—including fully welded AISI 304 stainless steel chamber construction with electropolished internal surfaces, zero-dead-leg fluid pathways, and traceable thermal uniformity across all 11 shelves—to ensure compliance with ICH Q5C, USP , and Annex 1 requirements for sterile product processing.

Key Features

• 14.76 m² total shelf area supports high-volume batch processing—capable of accommodating up to 66,400 vials (Ø16 mm) or 33,900 vials (Ø22 mm) per cycle, or 290 L of bulk solution.
• Deep-cold condenser operating at ≤–75 °C ensures efficient vapor capture during primary drying, minimizing backstreaming and maintaining stable vacuum conditions below 2.7 Pa.
• Shelf temperature control from –55 °C to +70 °C with ±0.5 °C uniformity (measured per ASTM F2668), enabled by low-viscosity silicone oil circulation and stress-relieved, laser-levelled shelves manufactured via uniform heating and precision machining.
• Full PLC-based automation with HMI interface; pre-programmable cycles stored in non-volatile memory support unattended operation, alarm logging, and real-time parameter trending.
• cGMP-aligned mechanical design: radiused internal corners, ground-and-polished welds, no crevices or stagnant zones, and validated cleanability per ISO 14644-1 Class 7 (ISO Class 10,000) environmental integration guidelines.
• Comprehensive qualification package available—including DQ/IQ/OQ documentation aligned with FDA 21 CFR Part 11 data integrity expectations and EU Annex 11 electronic record requirements.

Sample Compatibility & Compliance

The TF-SFD-15m²E accommodates diverse sample formats including glass vials (10–30 mL), trays (up to 1215 × 1215 mm), and bulk containers for nutraceutical powders, collagen hydrolysates, probiotic suspensions, and therapeutic peptides. Its validated shelf temperature distribution, low leak rate (≤0.1 Pa·m³/s), and precise vacuum regulation meet critical process windows defined in ISO 20988 (lyophilization process validation) and ASTM E2500 (verification of pharmaceutical equipment). All wetted parts conform to USP Class VI biocompatibility standards; chamber surface finish meets Ra ≤ 0.8 µm after electropolishing. The system supports full lifecycle compliance—from raw material receipt through final product release—under GLP, GMP, and ISO 9001:2015 quality management frameworks.

Software & Data Management

The integrated PLC control system records time-stamped, user-access-controlled data for all critical process parameters—including shelf temperature, chamber pressure, condenser temperature, and vacuum pump status—at configurable intervals (1–60 s). Audit trails are retained for ≥12 months and exportable in CSV/PDF format. Optional 21 CFR Part 11-compliant software modules provide electronic signatures, role-based access control, and automated report generation for batch records. Data archiving supports long-term trend analysis for continuous process verification (CPV) and annual product review (APR) requirements.

Applications

• Lyophilization of protein-based nutraceuticals (e.g., whey-derived bioactive peptides, lactoferrin, immunoglobulins)
• Stabilization of probiotic strains and enzyme formulations for dietary supplement manufacturing
• Processing of marine collagen, hyaluronic acid, and botanical extracts requiring thermal sensitivity preservation
• Scale-up from lab-scale freeze drying (e.g., pilot batches ≤5 kg) to commercial production (≥250 kg/year)
• Contract manufacturing organization (CMO) support for FDA/EMA-submitted dossiers requiring full equipment traceability and qualification evidence

FAQ

Does the TF-SFD-15m²E support automatic cycle optimization based on product thermograms?
Yes—when paired with optional shelf-sensor arrays and process analytical technology (PAT) interfaces, the system can integrate real-time product temperature feedback to dynamically adjust ramp rates and hold times.
Can the system be validated for terminal sterilization compatibility?
While the chamber itself is not designed for steam sterilization (SIP), it supports VHP (vaporized hydrogen peroxide) decontamination cycles validated per ISO 14644-3 and PDA TR No. 1.
Is remote monitoring and alarm notification supported?
Standard Ethernet/IP connectivity enables integration with SCADA systems; optional cloud-based dashboards provide SMS/email alerts for critical deviations.
What documentation is included for regulatory submissions?
Factory-issued FAT/SAT reports, 3Q protocols with raw data, calibration certificates (traceable to NIST), and material compliance declarations (RoHS, REACH, FDA 21 CFR 177.1520) are provided as standard.
Are spare parts and consumables stocked internationally?
Tianfeng maintains regional service hubs in Germany, Singapore, and the USA; critical spares—including condenser coils, vacuum pump oil, and silicone gaskets—are held in inventory with ≤72-hour dispatch SLA.
