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

Overview

The Tianfeng TF-LYO-30 is a pharmaceutical-grade, production-scale freeze dryer engineered for the robust, reproducible lyophilization of active pharmaceutical ingredients (APIs), peptide-based therapeutics—including oligopeptide repair formulations—and sterile drug products. It operates on the fundamental principle of sublimation under deep vacuum: frozen aqueous solutions are subjected to controlled primary drying (ice removal via sublimation) followed by secondary drying (desorption of bound water), resulting in stable, porous, low-moisture-content powders suitable for long-term storage and reconstitution. Designed for integration into GMP-compliant API manufacturing lines, the TF-LYO-30 features a rectangular stainless steel chamber (AISI 304), hydraulically actuated stoppering, and a fully programmable control architecture compliant with FDA 21 CFR Part 11 data integrity requirements when configured with audit trail and electronic signature modules.

Key Features

• Large-scale lyophilization capacity: 29.99 m² shelf area supports batch processing of up to 300 kg of material per cycle.
• High-efficiency condensation system: −75 °C ultimate condenser temperature with 600 kg/24 h ice capacity ensures rapid vapor removal during extended primary drying phases.
• Precision shelf temperature control: Uniform thermal distribution across shelves (−55 °C to +80 °C) achieved via low-viscosity silicone oil circulation and stress-relieved, laser-levelled AISI 304 shelves with polished, crevice-free welds.
• GMP-integrated mechanical design: Fully welded, electropolished interior with radiused corners; no dead-leg piping or inaccessible surfaces—validated for cleanability per ISO 14644-1 Class 5 (ISO Class 5) environments when installed with appropriate HVAC and isolator interfaces.
• Industrial-grade components: Bitzer scroll compressors, Baosi high-vacuum pumps, and Omron PLC controllers ensure long-term operational stability and reduced mean time between failures (MTBF).
• Hydraulic stoppering mechanism: Enables in-chamber, aseptic stopper insertion post-drying without breaking vacuum or exposing product to ambient conditions.

Sample Compatibility & Compliance

The TF-LYO-30 accommodates vials (16 mm and 22 mm diameters), trays, and custom containers used in API and oligopeptide formulation workflows. Its chamber geometry and shelf layout support automated loading/unloading via integrated conveyor systems, push-in/pull-out trolleys, and optional robotic interface protocols. The unit is manufactured under ISO 9001:2015 quality management systems and conforms to core elements of EU Annex 1, USP , and ICH Q5C guidelines for lyophilized biopharmaceuticals. Full qualification documentation—including Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ)—is available upon request. All wetted parts comply with USP Class VI biocompatibility standards, and surface finish meets Ra ≤ 0.8 µm specification for pharmaceutical contact surfaces.

Software & Data Management

The embedded Omron NJ-series PLC platform provides deterministic real-time control of shelf temperature ramps, chamber pressure profiles, condenser defrost cycles, and stoppering sequences. Process parameters are stored in non-volatile memory with timestamped event logging. Optional HMI upgrades include FDA 21 CFR Part 11–compliant software with role-based access control, electronic signatures, and audit trail generation. Data export formats include CSV and PDF for integration with LIMS and MES platforms. Batch records automatically generate structured e-records containing critical process parameters (CPPs), critical quality attributes (CQAs), and deviation flags—fully traceable for regulatory inspection and internal GLP/GMP audits.

Applications

The TF-LYO-30 is deployed in commercial API manufacturing facilities for lyophilizing thermolabile peptides, monoclonal antibody intermediates, enzyme inhibitors, and small-molecule APIs requiring moisture-sensitive stabilization. Its thermal uniformity and vacuum stability make it suitable for complex multi-step cycles involving annealing, controlled nucleation, and ramped secondary drying—essential for preserving structural integrity in oligopeptide repair compounds. Additional applications include lyophilization of diagnostic reagents, vaccine intermediates, and cell therapy cryopreservation matrices where residual moisture content must remain below 1.5% w/w and reconstitution time be consistently ≤60 seconds.

FAQ

Is the TF-LYO-30 compliant with current Good Manufacturing Practice (cGMP) requirements?
Yes—the equipment is designed, fabricated, and documented to meet cGMP Annex 1 principles for sterile processing, including material traceability, weld mapping, surface finish validation, and full 3Q qualification support.
Can the system be integrated with existing SCADA or MES infrastructure?
Yes—standard Modbus TCP and OPC UA communication protocols are supported; custom API gateways can be implemented for SAP EWM or Siemens Desigo integration.
What level of validation support is provided?
Tianfeng supplies complete IQ/OQ documentation packages, URS review assistance, and on-site PQ execution support by certified validation engineers.
Does the unit support nitrogen backfilling and inert gas purging?
Yes—optional integrated nitrogen purge manifolds with mass flow controllers and O₂ sensors are available for oxygen-sensitive APIs.
What is the typical lead time for delivery and commissioning?
Standard lead time is 12–16 weeks from PO confirmation, including FAT (Factory Acceptance Test); on-site SAT (Site Acceptance Test) and operator training are scheduled within 4 weeks of shipment.
