Tianfeng TF-FZG-50 Industrial-Scale Vacuum Freeze Dryer

Overview

The Tianfeng TF-FZG-50 Industrial-Scale Vacuum Freeze Dryer is a GMP-compliant, production-grade lyophilization system engineered for high-throughput, continuous batch processing of thermolabile materials. It operates on the principle of sublimation under deep vacuum and controlled low-temperature conditions: frozen water in the product matrix transitions directly from solid to vapor phase without passing through liquid state, preserving structural integrity, bioactivity, and sensory attributes. Designed for pharmaceutical, nutraceutical, food, and biotechnology manufacturing environments, this unit delivers reproducible drying kinetics across large-volume loads—supporting regulatory compliance in FDA-regulated facilities and ISO 22000-certified food production lines.

Key Features

• GMP-aligned construction: Main chamber and shelves fabricated from electropolished AISI 304 stainless steel with mirror-finish interior surfaces; zero dead-leg design ensures cleanability and meets hygienic process equipment standards (EHEDG Guideline Doc. 8, ASME BPE-2022).
• Integrated chamber–cold trap architecture with front-chamber/rear-trap configuration: Compact footprint, dual observation windows with integrated LED lighting, and fully accessible internal geometry for CIP validation.
• Customizable shelf system: Configurable as either extruded aluminum alloy shelves (enhanced thermal conductivity, uniform heat transfer) or AISI 304 stainless steel shelves (laser-welded, surface-textured for ease of cleaning and residue removal).
• High-capacity refrigeration: Dual-stage cascade refrigeration system using premium imported compressors (e.g., Bitzer, Danfoss); achieves ≤ −65 °C cold trap temperature within ≤ 90 minutes from ambient start-up.
• Robust vacuum generation: Modular vacuum pump train options—including ULVAC (Edwards) or Leybold dry scroll + roots booster configurations—deliver stable ≤ 2.7 Pa base pressure with real-time pressure profiling and leak-rate monitoring per ASTM E493.
• Intelligent control architecture: Omron NX-series PLC paired with industrial IPC running proprietary freeze-drying software; supports recipe management (≥ 100 stored protocols), stepwise parameter override during active cycles, and audit-trail-enabled operation per FDA 21 CFR Part 11 requirements.

Sample Compatibility & Compliance

The TF-FZG-50 accommodates diverse sample formats including bulk trays (up to 310 × 54 cm shelf size), stainless steel trolleys (2 units, SUS304), and custom mold-based loading configurations. It is validated for use with aqueous-based formulations ranging from seafood hydrolysates and instant beverage concentrates to herbal extracts, monoclonal antibody intermediates, and pet nutrition matrices. All wetted surfaces comply with USP , EC 1935/2004, and FDA 21 CFR 178.3570 for food-contact materials. System qualification documentation (DQ/IQ/OQ/PQ) is provided upon request, supporting GLP and cGMP implementation.

Software & Data Management

The embedded control platform logs ≥ 16 channels of real-time process data—including shelf temperature (−45 to +80 °C range, ±0.3 °C accuracy), chamber pressure (capacitance manometer, 0.001–1000 Pa range), condenser temperature, and vacuum pump status—at user-defined intervals (1–60 s). Data export is supported in CSV and PDF formats; encrypted database storage ensures traceability. Remote access via Wi-Fi or Ethernet enables off-site monitoring, alarm notification (SMS/email), and secure firmware updates. Full electronic signature support and configurable user roles align with ALCOA+ data integrity principles.

Applications

This system serves critical unit operations across multiple regulated sectors: stabilization of marine-derived peptides and omega-3 concentrates without lipid oxidation; production of shelf-stable fruit and vegetable powders retaining enzymatic activity and anthocyanin content; lyophilization of traditional Chinese medicinal decoctions under Good Agricultural and Collection Practices (GACP)-aligned protocols; and scalable drying of probiotic cultures and functional pet food ingredients. Its 50.31 m² effective drying area supports batch capacities exceeding 1,200 kg (wet weight) per cycle—making it suitable for contract manufacturing organizations (CMOs) and API manufacturers requiring ICH Q5C stability-compliant drying profiles.

FAQ

Is the TF-FZG-50 compliant with FDA 21 CFR Part 11 for electronic records and signatures?

Yes—the control system includes role-based authentication, time-stamped audit trails, and immutable data archiving with configurable retention policies.
Can shelf temperature be ramped independently per zone during primary drying?

No—shelves operate in uniform thermal mode; however, multi-step shelf temperature profiles are fully programmable and modifiable mid-cycle.
What vacuum pump configurations are available for sterile processing environments?

Dry vacuum solutions with oil-free scroll pumps and HEPA-filtered exhaust lines are offered to meet ISO Class 5 cleanroom compatibility requirements.
Does the system support automated defrosting with validation-ready cycle reports?

Yes—steam-assisted defrosting is available with integrated temperature mapping and post-defrost residual moisture verification reporting.
Are IQ/OQ documents included with delivery?

Standard delivery includes factory acceptance test (FAT) reports; site-specific IQ/OQ protocols and execution services are available as optional engineering support packages.
