Tianfeng TF-FZG-50 Industrial Freeze Dryer with 50 m² Shelf Area

Overview

The Tianfeng TF-FZG-50 Industrial Freeze Dryer is a GMP-compliant, production-scale lyophilization system engineered for high-reliability continuous operation in food, nutraceutical, and functional ingredient manufacturing environments. Based on the fundamental principles of sublimation under deep vacuum and controlled low-temperature heat transfer, this unit removes water from thermolabile materials—such as sea cucumber, fish fillets, and fresh milk—by freezing the product to below its eutectic point, then reducing ambient pressure to enable direct phase transition from ice to vapor without passing through the liquid phase. Its integrated front-chamber/rear-trap architecture minimizes footprint while maintaining structural rigidity and thermal isolation between drying and condensation zones. Constructed entirely from electropolished SUS 304 stainless steel per ISO 8573-1 and ASME BPE surface finish standards, the chamber features mirror-finish interior surfaces (Ra ≤ 0.4 µm), zero dead-leg geometry, and fully drainable slopes—ensuring full compliance with FDA 21 CFR Part 11–ready cleaning validation protocols.

Key Features

• GMP-engineered chamber and shelf assembly fabricated from seamless 304 stainless steel with electropolished internal surfaces and CIP-compatible sloped drainage design
• Integrated cold trap with dual-stage refrigeration circuit achieving ≤ −65 °C operating temperature and 800 kg/24 h ice capacity at ≤ 2.7 Pa ultimate vacuum
• Modular shelf configuration: (15 + 1) × 2 shelves (including temperature-compensated reference plate), each measuring 3100 × 541 × 18 mm; optional aluminum or 304 stainless steel construction
• Omron CJ2M-series PLC control system with real-time data logging, recipe management (up to 99 programs), and stepwise process override capability during active cycles
• TFD-5000 proprietary HMI software running on industrial-grade touch-panel PC, supporting audit trail, electronic signatures, and automated report generation per 21 CFR Part 11 Annex 11 requirements
• Steam-assisted or immersion-based defrost system with ≥ 4 ton/batch hot water consumption (P ≥ 3 bar, T = 80 °C), enabling rapid, residue-free trap regeneration
• Full-spectrum cooling water interface: 50 m³/hr flow rate, inlet pressure 1.5–2.0 bar, max inlet temperature ≤ 28 °C

Sample Compatibility & Compliance

The TF-FZG-50 accommodates bulk-loaded trays, stainless steel trolleys (1500 × 1400 mm, two units included), and custom-fit stainless carriers for viscous or particulate-laden matrices—including whole-muscle seafood cuts, homogenized dairy concentrates, and fragmented marine biomass. Its temperature range (−50 °C to +80 °C) and programmable shelf ramping support both slow-freeze crystallization and rapid vitrification strategies, making it suitable for products with complex eutectic behavior. All wetted surfaces conform to ISO 22000:2018 food safety management criteria and EU Regulation (EC) No. 1935/2004 for materials in contact with foodstuffs. Documentation packages include Factory Acceptance Test (FAT) reports, material traceability certificates (EN 10204 3.1), and IQ/OQ protocol templates aligned with WHO TRS 986 Annex 6 and ICH Q5C stability guidelines.

Software & Data Management

The TFD-5000 control platform provides role-based user access (Operator, Technician, Administrator), time-stamped event logging with immutable audit trails, and configurable alarm thresholds for vacuum deviation (> ±0.3 Pa), shelf temperature drift (> ±1.5 °C), and condenser overload. Process data—including shelf temperature profiles, chamber pressure curves, and condenser load accumulation—is exported in CSV or PDF format with embedded digital signatures. The system supports integration into MES platforms via OPC UA (v1.04) and includes built-in validation tools for periodic requalification per ASTM F2476-21 and USP . Firmware updates are delivered remotely via secure HTTPS channel with SHA-256 signature verification; all versions remain backward-compatible with legacy recipe libraries.

Applications

This freeze dryer serves primary applications in scalable preservation of high-value biological matrices where enzymatic activity, protein conformation, and volatile compound retention are critical. Typical use cases include: stabilization of hydrolyzed marine collagen peptides from sea cucumber tissue; low-thermal degradation drying of minced white fish muscle for pet nutrition formulations; conversion of raw bovine colostrum and pasteurized whole milk into shelf-stable powder with intact immunoglobulin G (IgG) titers; and dehydration of fermented probiotic cultures embedded in fruit puree carriers. It also supports pilot-scale process development for regulatory submissions under EFSA Novel Food dossiers and FDA GRAS notifications—particularly where residual moisture content (< 2.5 % w/w), reconstitution time (< 90 s), and microbiological limits (total aerobic count < 10² CFU/g) must be rigorously demonstrated.

FAQ

Is the TF-FZG-50 compliant with current Good Manufacturing Practice (cGMP) requirements for food-grade production?
Yes—the chamber, shelves, and piping meet ASME BPE-2022 hygienic design standards, and the control architecture satisfies FDA 21 CFR Part 11 data integrity mandates including audit trail, electronic signature, and change control.
Can shelf temperature uniformity be validated across the full 50 m² area?
Yes—each shelf is individually PID-controlled with redundant PT100 sensors; temperature mapping studies per ISO 14644-3 and EU GMP Annex 15 are supported by pre-installed sensor ports and calibration documentation.
What vacuum pump configurations are available for different regulatory environments?
Standard configuration uses ULVAC (formerly Unisem) oil-free dry pumps meeting ISO 8573-1 Class 0 purity; alternative options include Edwards nXDS series for pharmaceutical-grade sterile environments or Busch R5 RA for high-throughput food applications.
Does the system support remote monitoring and predictive maintenance?
Yes—via optional MQTT-enabled gateway module, real-time KPIs (condenser delta-T, vacuum recovery time, compressor amperage variance) feed into cloud-based analytics dashboards compatible with Siemens MindSphere and PTC ThingWorx.
Are spare parts and technical documentation available internationally?
Yes—Tianfeng maintains regional spares hubs in Rotterdam, Singapore, and Chicago; English-language OQ/IQ templates, exploded diagrams, and CE/UKCA declarations are provided with every shipment.
