田枫TF-FZG-150 Industrial-Scale Freeze Dryer (Lyophilizer)

Overview

The Tianfeng TF-FZG-150 is a fully integrated, production-scale freeze dryer engineered for high-reliability lyophilization of heat-sensitive biological and food-grade materials. Based on the fundamental principles of sublimation under deep vacuum and controlled thermal energy transfer, this system operates by freezing product loads to below their eutectic temperature, then reducing ambient pressure to enable direct phase transition from ice to vapor—preserving structural integrity, enzymatic activity, and nutritional composition without liquid-phase degradation. Its monolithic chamber-and-cold-trap architecture minimizes footprint while maximizing condensation efficiency and process reproducibility. Designed specifically for continuous batch processing in regulated environments, the TF-FZG-150 meets foundational hygienic design criteria aligned with ISO 22000, FDA 21 CFR Part 11 (when configured with audit-trail-enabled software), and EU GMP Annex 15 prerequisites for validation-ready equipment.

Key Features

• Monolithic cylindrical chamber constructed from electropolished SUS 304 stainless steel (Ra ≤ 0.4 µm), conforming to ASME BPE surface finish standards and eliminating microbial harborage points.
• Shelf system comprises 32 temperature-controlled plates (30 active + 2 compensation shelves), configurable in either anodized aluminum (optimized for rapid thermal response) or mirror-finished SUS 304 (prioritizing cleanability and corrosion resistance).
• Cold trap features seamless, sanitary-grade stainless steel coil construction with ≤−65 °C ultimate temperature capability and verified 2000 kg/24 h ice capture capacity under ISO 13485-compliant test conditions.
• Omron CJ2M-series PLC serves as the deterministic control core, supporting dual-mode operation (automatic recipe-driven and manual stepwise), real-time parameter override, dynamic step-jumping, and multi-profile storage (≥1000 cycles).
• TFD-5000 control software platform provides full data logging (pressure, shelf temp, chamber temp, condenser temp, vacuum rate), electronic signature support, and optional 21 CFR Part 11 compliance modules including user role management and immutable audit trails.
• Integrated steam-assisted defrost system enables rapid, residue-free ice removal within ≤45 minutes per cycle, with validated temperature uniformity across the entire condenser surface (±1.5 °C).
• Front-access observation window with IP65-rated LED illumination permits non-invasive visual monitoring without vacuum interruption or sterility compromise.

Sample Compatibility & Compliance

The TF-FZG-150 accommodates bulk-loaded food matrices—including fruits, vegetables, seafood (e.g., sea cucumber), meat derivatives, herbal extracts, and instant beverage powders—on standard 6 trolleys with load capacities up to 1500 kg per cycle. All wetted surfaces comply with FDA 21 CFR 178.3570 (food-contact stainless steel) and EC 1935/2004 requirements. Structural design incorporates CIP-ready geometry: no horizontal ledges, fully drainable slopes (>1.5°), and weld joints polished to ISO 15614-1 certification level. Documentation packages include FAT/SAT protocols, material traceability dossiers (EN 10204 3.1), and IQ/OQ templates compatible with GLP and GMP validation frameworks.

Software & Data Management

The TFD-5000 software suite runs on an industrial-grade touch-panel HMI (Omron NS series) and interfaces directly with the PLC via EtherCAT. It records all critical process parameters at user-defined intervals (minimum 1 sec), stores raw data in encrypted .CSV and proprietary .TFL formats, and supports export to LIMS-compatible XML schemas. Version-controlled firmware updates are delivered free-of-charge throughout the equipment lifecycle. Optional modules include remote diagnostics via TLS-secured MQTT, automated report generation (PDF/Excel), and integration with MES platforms through OPC UA server implementation.

Applications

This system is deployed in commercial food processing facilities requiring stable, scalable preservation of bioactive compounds—particularly in marine-derived nutraceuticals (e.g., Apostichopus japonicus—sea cucumber—where collagen tertiary structure and sulfated glycosaminoglycan content must be retained). It also supports pilot-scale development of functional ingredients for infant formula, clinical nutrition formulations, and traditional Chinese medicine granules where moisture content must remain <1.5% w/w post-lyophilization. Process repeatability is verified per ISO 13408-1:2018 for lyophilization cycle consistency (RSD < 2.1% across 3 consecutive validation batches).

FAQ

Is the TF-FZG-150 suitable for pharmaceutical-grade lyophilization?
Yes—when equipped with optional HEPA-filtered nitrogen backfill, PAT-integrated NIR probes, and 21 CFR Part 11-compliant software licensing, it satisfies baseline requirements for Phase I–II clinical trial material production.
What validation documentation is provided?
Standard delivery includes Factory Acceptance Test (FAT) report, material certifications (EN 10204 3.1), electrical safety compliance (IEC 61000-6-4), and IQ/OQ protocol templates aligned with ASTM E2500-13.
Can shelf temperature uniformity be mapped?
Yes—the system supports thermocouple insertion ports at all 32 shelf levels; qualification per ISO 13408-1 Annex C requires ±1.0 °C max deviation across loaded shelves.
What cooling infrastructure is required?
A dedicated closed-loop chiller delivering 200 m³/hr at ≤25 °C inlet temperature and 1.5–2 bar pressure is mandatory; field verification of flow stability is conducted during SAT.
Is remote monitoring supported out-of-the-box?
Basic remote status viewing is enabled via embedded web server; secure remote access and alarm notification require optional TFD-Cloud Gateway module.
