Tianfeng TF-FZG-30 Industrial-Scale Vacuum Freeze Dryer

Overview

The Tianfeng TF-FZG-30 is an industrial-scale vacuum freeze dryer engineered for continuous, GMP-compliant lyophilization of heat-sensitive materials across food processing, traditional Chinese medicine (TCM), and fine chemical manufacturing. Based on the fundamental principles of sublimation—where ice transitions directly from solid to vapor under controlled low-pressure and low-temperature conditions—the system removes moisture without inducing thermal degradation, preserving structural integrity, bioactivity, solubility, and shelf life. Designed for production environments requiring batch capacities up to 300 L of aqueous solution or equivalent solid load, the TF-FZG-30 integrates a robust stainless-steel chamber architecture with high-efficiency refrigeration and vacuum dynamics. Its 30 m² shelf area supports scalable throughput while maintaining uniform temperature distribution and pressure stability across all 11 shelves (10 working + 1 bottom shelf), enabling reproducible process outcomes in compliance with ISO 22000, FDA 21 CFR Part 11 (when paired with validated software), and WHO TRS Annex 7 requirements for pharmaceutical-grade equipment.

Key Features

• GMP-Compliant Construction: Chamber and shelves fabricated from electropolished AISI 304 stainless steel with mirror-finish interior surfaces; zero dead-leg design ensures full cleanability and meets hygienic standards for food and pharma applications.
• Integrated Chamber-Cold Trap Configuration: Front-chamber/rear-cold trap layout minimizes footprint and improves thermal isolation; observation window with integrated LED lighting enables real-time visual monitoring without compromising vacuum integrity.
• Modular Shelf Options: Selectable shelf material—high-conductivity extruded aluminum (brushed surface, precision flatness) or 304 stainless steel (weld-free square-tube construction)—each optimized for thermal transfer efficiency and ease of CIP/SIP validation.
• High-Capacity Condenser: Double-wall, sanitary-grade stainless steel condenser coil operating at ≤ −65 °C; available in monolithic or modular configurations to support maintenance flexibility and contamination control.
• Industrial Refrigeration System: Fully imported compressors, expansion valves, and oil separators ensure rapid cooldown (< 90 min to −65 °C), stable shelf temperature control (±1.5 °C), and long-term operational reliability under 24/7 duty cycles.
• Multi-Option Vacuum Architecture: Configurable vacuum pump train based on ULVAC-derived technology—capable of achieving and sustaining ≤2.7 Pa ultimate pressure with low hydrocarbon backstreaming and minimal particulate generation.
• Omron PLC-Based Control Platform: Supports dual-mode operation (automatic & manual), multi-step recipe storage (>100 protocols), real-time parameter adjustment during drying, and step-skipping functionality for process troubleshooting and optimization.
• Validated Defrosting: Steam or immersion defrosting modes reduce cycle downtime; automated drainage and condensate detection prevent cross-contamination between batches.

Sample Compatibility & Compliance

The TF-FZG-30 accommodates diverse sample formats including bulk liquids (soups, broths, herbal extracts), pre-filled trays (meat strips, fruit slices, functional powders), and encapsulated intermediates. It supports lyophilization of proteins, probiotics, enzymes, and botanical actives where residual moisture content must remain below 2–3% w/w. All wetted parts comply with FDA 21 CFR 178.3570 (indirect food additives) and EU Regulation (EC) No. 1935/2004. Structural design adheres to ASME BPVC Section VIII Div. 1 for pressure boundary integrity and EN 61000-6-2/6-4 for electromagnetic compatibility. Documentation packages include FAT/SAT reports, IQ/OQ templates, and material traceability dossiers aligned with GMP Annex 15 and ISO 9001:2015 quality management systems.

Software & Data Management

The embedded Omron NX-series PLC provides deterministic real-time control with onboard data logging (≥1 year at 1-second resolution). Historical datasets—including shelf temperature profiles, chamber pressure curves, condenser temperature trends, and vacuum pump current—are exportable via USB or Ethernet to CSV or SQLite formats. Optional HMI upgrade adds audit trail capability compliant with FDA 21 CFR Part 11 (electronic signatures, user access levels, change history). Data archiving supports integration into MES/LIMS platforms through Modbus TCP or OPC UA protocols. All firmware updates undergo version-controlled release testing per IEC 62304 Class B software safety standards.

Applications

• Food Industry: Primary drying of cooked meats (beef jerky, poultry strips), seafood, fruits, vegetables, and instant meal components—retaining color, texture, rehydration kinetics, and nutritional value.
• Traditional Chinese Medicine: Stabilization of volatile oils, polysaccharides, and alkaloid-rich extracts without solvent residue or Maillard browning.
• Biotechnology & Nutraceuticals: Processing of live bacterial cultures (e.g., Lactobacillus, Bifidobacterium), yeast-based fermentation products, and enzyme blends requiring >90% viability retention post-lyophilization.
• Chemical Intermediates: Dehydration of catalysts, metal-organic frameworks (MOFs), and specialty polymers where crystallinity and surface area must be preserved.

FAQ

What regulatory certifications does the TF-FZG-30 carry?
It is manufactured under ISO 9001:2015 and conforms to GMP Annex 1 (EU), USP <1211>, and China’s YY/T 0287-2017 (equivalent to ISO 13485). CE marking applies to electrical safety (EN 61000-6-2/6-4) and machinery directive (2006/42/EC).
Can the system be validated for pharmaceutical use?
Yes—full IQ/OQ documentation kits are provided; PQ support includes thermocouple mapping (ASTM E2297), vacuum leak testing (ISO 10079-2), and moisture analysis correlation (Karl Fischer titration per USP <921>).
Is remote monitoring supported?
Standard Ethernet port enables SCADA-level supervision; optional 4G/WiFi module allows cloud-based alarm notification and limited parameter readout via secure TLS tunnel.
What maintenance intervals are recommended?
Vacuum pump oil change every 2000 operating hours; refrigerant circuit inspection annually; shelf surface passivation and gasket replacement every 3 years or after 500 cycles—per maintenance logbook guidance included with delivery.
Does the system support sterile processing?
While not classified as an aseptic isolator, the unit supports SIP (steam-in-place) when integrated with external steam generators and validated per HTM 2030 or PDA TR#1 guidelines.
