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

Overview

The Tianfeng TF-FZG-50 is an industrial-scale vacuum freeze dryer engineered for continuous, high-throughput lyophilization of heat-sensitive materials under controlled low-temperature and high-vacuum conditions. Based on the fundamental principle of sublimation—where ice transitions directly from solid to vapor phase without passing through liquid—the system removes water from frozen products while preserving structural integrity, enzymatic activity, nutritional profile, and volatile compound composition. Designed for GMP-compliant production environments, it serves as a core unit in food processing (e.g., fruit, vegetable, meat, seafood, instant beverages), traditional Chinese medicine (TCM) herb preservation (including ginseng), nutraceutical manufacturing, biopharmaceutical intermediates, and premium pet food production. Its integrated front-chamber/rear-condenser architecture optimizes thermal efficiency and spatial footprint, supporting scalable batch processing with reproducible cycle fidelity across regulatory-grade operations.

Key Features

• GMP-aligned chamber construction: AISI 304 stainless steel body with mirror-finish internal polishing, zero dead-leg design, and fully cleanable geometry compliant with hygiene-critical applications.
• Modular shelf configuration: Dual-tier arrangement of (15+1)×2 shelves (310 × 54 × 1.8 cm each), with 77 mm inter-shelf spacing; customizable shelf material options—high-conductivity extruded aluminum or electropolished 304 stainless steel—for optimized heat transfer and ease of sanitation.
• High-capacity refrigeration system: Imported high-efficiency compressors and components delivering rapid cooling to ≤−65 °C cold trap temperature, enabling efficient vapor capture during primary drying.
• Robust vacuum architecture: ULVAC (formerly ULVAC-ASTEC) high-performance vacuum pump assembly ensures stable operation at ≤2.7 Pa ultimate pressure, with optional multi-pump configurations for varying load profiles and process redundancy.
• Intelligent control platform: Omron PLC-based automation integrated with industrial PC (IPC) featuring embedded Wi-Fi, remote monitoring capability, audit-trail-enabled data logging, and full compliance with FDA 21 CFR Part 11 electronic record requirements.
• Dual-mode defrosting: Steam or immersion defrost options ensure rapid, residue-free cold trap cleaning between batches—critical for cross-contamination prevention in multi-product facilities.

Sample Compatibility & Compliance

The TF-FZG-50 accommodates diverse sample formats including bulk trays, stainless steel trolleys (2 units, SUS304), and custom molds—supporting both liquid and solid matrices with uniform heat distribution across 50.31 m² effective drying area. It meets ISO 9001:2015 quality management standards and adheres to hygienic design principles aligned with EHEDG Guideline Doc. 8 and ASME BPE-2022. For pharmaceutical and TCM applications, its validated process parameters support alignment with ICH Q5C (stability), USP , and Chinese Pharmacopoeia (ChP) General Chapter 0261. All wetted surfaces are electropolished to Ra ≤0.4 µm, minimizing microbial adhesion and facilitating CIP/SIP readiness.

Software & Data Management

The embedded IPC runs proprietary lyo-control software offering recipe-driven operation with up to 99 programmable drying cycles. Each cycle includes configurable ramp rates, hold times, shelf temperature setpoints (−45 °C to +80 °C), and real-time vacuum feedback control. All process data—including shelf temperature, chamber pressure, condenser temperature, and time-stamped event logs—are automatically archived in encrypted CSV/SQL format with timestamped user authentication. The system supports optional integration with MES/LIMS platforms via OPC UA or Modbus TCP, enabling traceability for GLP/GMP audits. Remote access allows secure off-site supervision, alarm notification via email/SMS, and firmware updates over HTTPS.

Applications

• Food industry: Preservation of berries, citrus powders, mushroom extracts, fish hydrolysates, and functional beverage concentrates without Maillard degradation or oxidation.
• Traditional herbal medicine: Stabilization of Panax ginseng saponins, Astragalus polysaccharides, and Cordyceps militaris metabolites while retaining pharmacodynamic potency.
• Nutraceuticals & probiotics: Lyophilization of live bacterial cultures (e.g., Lactobacillus spp.), enzymes (bromelain, papain), and phytochemical isolates requiring strict moisture control (<1% w/w).
• Pet nutrition: Production of single-ingredient freeze-dried pet treats (chicken liver, salmon, green tripe) meeting AAFCO moisture limits and palatability benchmarks.
• Biotherapeutics: Pre-formulation drying of monoclonal antibody intermediates, vaccine candidates, and diagnostic reagents prior to final vial filling.

FAQ

Is the TF-FZG-50 suitable for Good Manufacturing Practice (GMP) environments?

Yes—it is constructed to GMP Annex 1 hygienic standards, with full documentation packages (DQ/IQ/OQ/PQ templates) available upon request.
Can shelf temperature be independently controlled per layer?

No—shelves operate in uniform thermal zones; however, dual-zone heating/cooling is available as an optional upgrade.
What validation support does Tianfeng provide?

Tianfeng supplies FAT/SAT protocols, IQ/OQ documentation kits, and on-site commissioning assistance by certified field engineers.
Does the system comply with FDA 21 CFR Part 11 for electronic records?

Yes—audit trail, electronic signatures, and role-based access control are natively implemented in the IPC software.
Is remote troubleshooting supported?

Yes—via secure VPN-enabled remote desktop access with customer consent and session logging.
