Tianfeng TF-FZG-300 Industrial Freeze Dryer (296 m² Shelf Area)

Overview

The Tianfeng TF-FZG-300 is a large-scale, GMP-compliant industrial freeze dryer engineered for continuous batch processing of heat-sensitive biological and food-grade materials. Based on the fundamental principles of sublimation under controlled low-pressure and cryogenic conditions, this system removes water from frozen products via primary drying (sublimation) followed by secondary drying (desorption), preserving structural integrity, bioactivity, and nutritional profile. Designed specifically for high-throughput manufacturing environments, the TF-FZG-300 delivers 296 m² of effective shelf area—among the largest standard configurations available in the industrial freeze-drying segment—and supports batch loads up to 3 metric tons per cycle. Its integrated chamber–cold trap architecture minimizes footprint while maintaining thermal separation between drying and condensation zones, ensuring stable vacuum performance and efficient ice capture during extended operation.

Key Features

• GMP-aligned construction: Main chamber and shelves fabricated from electropolished AISI 304 stainless steel with mirror-finish interior surfaces and zero-hygiene-dead-zone geometry.
• Modular shelf configuration: (15+1) × 2 × 2 shelf arrangement; customizable shelf material options—including high-thermal-conductivity anodized aluminum or 304 stainless steel with brushed surface finish—optimized for uniform heat transfer and cleanability.
• High-capacity refrigeration system: Dual-stage cascade refrigeration using premium imported compressors; achieves cold trap temperature ≤ −65 °C within ≤ 180 minutes from ambient.
• Vacuum performance: Equipped with ULVAC (formerly Anelva) high-efficiency vacuum pump assemblies; maintains ultimate pressure ≤ 2.7 Pa across full operational load range.
• Intelligent control architecture: Omron CJ2M PLC paired with industrial IPC running proprietary freeze-drying software; supports multi-step recipe programming, real-time parameter override, step-jumping, and automatic data logging with timestamped audit trails.
• Operational flexibility: Dual-mode defrosting (steam or immersion); optional electric shelf heating (48 kW × 6 zones); Wi-Fi-enabled remote monitoring and diagnostics compliant with ISO/IEC 27001 secure communication protocols.

Sample Compatibility & Compliance

The TF-FZG-300 accommodates diverse sample formats including bulk trays (SUS304 trolleys, 12 units standard), stacked trays, and custom racks for irregular geometries. It is routinely deployed for freeze-drying of functional foods (e.g., fruit crisps, instant soups), nutraceuticals (Cordyceps militaris mycelium, leech-derived peptides), pet nutrition matrices, marine hydrolysates, and botanical extracts. All wetted parts meet FDA 21 CFR Part 11 requirements for electronic records and signatures when configured with audit-trail-enabled software. The system complies with ISO 22000 (food safety), ISO 13485 (if used in medical device ancillary processing), and EU GMP Annex 15 guidelines for validation of lyophilization processes. Documentation packages include IQ/OQ/PQ protocols, material traceability records, and weld map certification per ASME BPE-2022.

Software & Data Management

The embedded freeze-drying control software provides full lifecycle data governance—from recipe creation and execution to post-process analysis. Each batch generates a structured .CSV and encrypted .PDF report containing time-stamped shelf temperature, chamber pressure, condenser temperature, vacuum ramp rate, and power consumption profiles. Data storage conforms to 21 CFR Part 11 standards, featuring role-based access control, electronic signature capture, and immutable audit logs. Optional integration with MES/SCADA platforms (via OPC UA or Modbus TCP) enables centralized production monitoring and SPC charting. Backups are automatically synchronized to on-premise NAS or validated cloud infrastructure with AES-256 encryption.

Applications

• Pharmaceutical intermediates and herbal extract powders requiring residual moisture < 2% w/w.
• Functional food ingredients—such as Cordyceps sinensis and Cordyceps militaris mycelial biomass—where enzymatic activity and polysaccharide conformation must be preserved.
• Marine-derived biomaterials including Hirudo medicinalis (medicinal leech) tissue powders, where protease stability and anticoagulant peptide integrity are critical.
• Ready-to-eat pet snacks and aquaculture feed supplements requiring extended ambient shelf life without preservatives.
• High-value seafood derivatives (e.g., fish collagen hydrolysates, krill oil microcapsules) processed under oxygen-limited, low-thermal-stress conditions.

FAQ

Is the TF-FZG-300 suitable for cGMP-certified pharmaceutical manufacturing?
Yes—when equipped with validated software, calibrated sensors, and documented IQ/OQ/PQ protocols, it meets core requirements for non-sterile API and excipient lyophilization under ICH Q5C and USP <1211>.
Can shelf temperature be independently controlled per zone?
Yes—the system supports 6 independent electric heating zones (48 kW each), enabling precise thermal profiling across heterogeneous loads.
What level of vacuum stability is maintained during extended drying cycles?
Under nominal load, pressure fluctuation remains within ±0.3 Pa over 24-hour operation, verified per ASTM E2877-13 test methodology.
Does Tianfeng provide installation qualification support?
Yes—on-site commissioning, FAT/SAT documentation, and operator training are included in turnkey delivery packages.
Are spare parts and service technicians available internationally?
Yes—Tianfeng maintains regional technical hubs in Germany, Singapore, and Mexico; all critical components carry 12-month warranty and are stocked globally.
