Tianfeng TF-FZG-200 Industrial-Scale Freeze Dryer

Overview

The Tianfeng TF-FZG-200 Industrial-Scale Freeze Dryer is a GMP-compliant, production-grade lyophilization system engineered for continuous, high-throughput processing of heat-sensitive biological and food materials. Operating on the fundamental principle of sublimation—where ice transitions directly from solid to vapor under controlled low-pressure and low-temperature conditions—the TF-FZG-200 enables preservation of structural integrity, enzymatic activity, volatile compounds, and nutritional profile in bulk batches up to 2000 kg per cycle. Designed for integration into certified manufacturing environments, the unit features a monolithic chamber–cold trap architecture with front-loading shelf configuration, minimizing footprint while maximizing thermal uniformity and vacuum stability across its 197.4 m² effective drying area. Its ≤ 2.7 Pa ultimate vacuum performance, coupled with a ≤ −65 °C cold trap temperature and 3000 kg/24 h condensate capacity, ensures rapid primary drying kinetics and robust moisture removal for challenging matrices including seafood, pet nutrition, herbal extracts, ready-to-eat meals, and functional food ingredients.

Key Features

• GMP-compliant construction: Chamber and shelves fabricated from electropolished 304 stainless steel with mirror-finish interior surfaces and zero-hygiene-dead-zone geometry; fully compliant with ASME BPVC Section VIII Div. 1 and FDA 21 CFR Part 11 design expectations for audit-ready documentation.
• Integrated chamber–cold trap architecture: Rear-mounted, high-efficiency stainless steel coil condenser with optional modular or monoblock configuration; optimized for minimal thermal lag and maximal ice entrapment efficiency.
• Dual-material shelf system: Configurable with either extruded anodized aluminum shelves (enhanced thermal conductivity, ±0.5 °C uniformity) or 304 stainless steel shelves (superior cleanability, steam-in-place compatibility); 32 total shelves arranged in two independent columns with 77 mm vertical spacing.
• High-fidelity process control: Omron CJ2M-series PLC paired with industrial PC running proprietary lyoOS v4.2 firmware; supports ≥100 user-defined recipes, real-time parameter override, step-jump functionality, and full-cycle data logging at 1-second resolution.
• Energy-optimized refrigeration: Multi-stage cascade refrigeration system using ultra-low-GWP refrigerants (R513A/R134a), incorporating Danfoss/Embraco compressors, microchannel condensers, and adaptive load-balancing logic for stable −65 °C cold trap operation under variable ambient loads.
• Flexible vacuum management: Modular vacuum train based on ULVAC (formerly Anshin) dry scroll and oil-sealed rotary vane pump combinations; includes inline particle filtration, vapor trapping, and real-time pressure gradient monitoring via capacitance manometers.

Sample Compatibility & Compliance

The TF-FZG-200 accommodates heterogeneous sample formats including trays (standard 1216 × 540 mm), stainless steel trolleys (8 units, SUS304), and custom rack systems for pouches, vials, or irregularly shaped food blocks. It meets ISO 22000:2018 hygiene requirements for food processing equipment and aligns with ICH Q5C stability testing guidance for biologics when operated under validated protocols. All wetted surfaces comply with FDA 21 CFR 178.3570 (indirect food additives) and EU Regulation (EC) No. 1935/2004. The system supports GLP/GMP audit readiness through electronic signature-enabled recipe management, time-stamped event logs, and full traceability of all critical process parameters (shelf temp, chamber pressure, condenser temp, elapsed time).

Software & Data Management

The embedded lyoOS platform provides dual-mode operation (automatic sequence control / manual override), password-protected user roles (Operator, Technician, Administrator), and native support for CSV/Excel export of raw process data. All operational events—including alarm triggers, recipe changes, door openings, and power interruptions—are timestamped with millisecond precision and archived with SHA-256 hash integrity verification. Remote access via encrypted TLS 1.3 channel enables off-site monitoring, diagnostic review, and secure firmware updates without compromising local network security. Audit trails conform to Annex 11 and 21 CFR Part 11 requirements, including electronic signatures, retention policies (>10 years), and immutable log history.

Applications

• Food & Nutrition: Large-batch freeze-drying of mushrooms (e.g., Auricularia polytricha), duck meat, berries, vegetables, pet treats, and functional snack formulations requiring 95% rehydration fidelity.
• Phytopharmaceuticals: Stabilization of botanical extracts, enzyme-rich powders, and traditional Chinese medicine (TCM) decoctions without solvent residue or thermal degradation.
• Seafood Processing: Preservation of shrimp, scallops, and fish fillets while retaining texture, color, and omega-3 fatty acid integrity under oxygen-controlled loading protocols.
• Contract Manufacturing: Turnkey lyophilization services for OEM clients requiring cGMP-aligned infrastructure, validation documentation packages (IQ/OQ/PQ), and batch record templates compliant with EU GMP Annex 15.

FAQ

Is the TF-FZG-200 suitable for pharmaceutical-grade lyophilization?
Yes—when configured with HEPA-filtered nitrogen backfill, sterile barrier isolators, and qualified sterilization cycles (SIP), it meets core requirements of EU GMP Annex 1 and USP <1211> for non-sterile and terminal sterilization applications.
Can shelf temperature be independently controlled per zone?
No—the current configuration employs uniform shelf heating/cooling across all 32 plates; however, zonal control is available as an optional upgrade using segmented PID loops and dedicated thermocouple arrays.
What validation documentation is provided with delivery?
Standard package includes Factory Acceptance Test (FAT) report, Material Certificates (EN 10204 3.1), Pressure Vessel Certification, and Electrical Safety Compliance Report (IEC 61000-6-2/4). IQ/OQ protocol development and execution are offered as a separate service.
Does the system support automated cleaning-in-place (CIP)?
CIP is not integrated by default but can be retrofitted with sanitary spray ball manifolds, conductivity sensors, and programmable rinse-hold-drain sequences compatible with common food-grade detergents and sanitizers.
How is remote troubleshooting performed?
Via secure TeamViewer-hosted industrial VPN connection with screen-sharing capability, real-time PLC tag monitoring, and diagnostic log download—all governed by pre-signed SLA agreements covering response time and resolution windows.
