Tianfeng TF-FZG-20 Industrial-Scale Freeze Dryer for Beef and Bird’s Nest Extract Processing

Overview

The Tianfeng TF-FZG-20 is an industrial-scale, GMP-compliant freeze dryer engineered for high-volume, process-critical lyophilization of heat-sensitive biological and food-grade materials—including beef-derived proteins, hydrolyzed collagen matrices, and bird’s nest extract solutions. Based on the fundamental principles of sublimation under controlled low-pressure and cryogenic conditions, this system operates by freezing the product to below its eutectic temperature, then reducing chamber pressure to induce direct phase transition from ice to vapor—bypassing the liquid phase entirely. This preserves structural integrity, bioactivity, solubility, and shelf stability far more effectively than conventional drying methods. Designed as a fully integrated unit with front-chamber/rear-condenser architecture, it eliminates inter-unit transfer risks and supports closed-system processing—a key requirement for hygienic production environments in nutraceutical, functional food, and bioprocessing applications.

Key Features

• GMP-aligned construction: Cylindrical chamber and condenser fabricated from mirror-finished SUS 304 stainless steel; internal surfaces polished to Ra ≤ 0.4 µm for cleanability and microbial control.
• Integrated pre-freezing capability: Eliminates need for external ultra-low temperature freezers, mitigating cross-contamination and phase separation during material handling.
• 11-shelf configuration (10 working + 1 radiant top shelf): All shelves are precision-machined from 304 stainless steel with brushed-surface finish and uniform 70 mm spacing for optimal airflow and thermal homogeneity.
• High-capacity condenser: Cylindrical coil design with SUS 304 tubing, rated for 400 kg ice capture per 24-hour cycle and capable of reaching ultimate temperatures of −65°C to −70°C.
• Dual-mode defrost system: Supports both steam-assisted and immersion-based defrost protocols, enabling rapid, residue-free maintenance between batches.
• Intelligent control architecture: Omron PLC paired with industrial touchscreen IPC running proprietary TFD-5000 software—supporting recipe management, real-time parameter logging, and audit-ready event history.
• Thermal regulation via silicone oil circulation: Shelf heating/cooling achieved without steam, ensuring intrinsic safety, energy efficiency, and compliance with ISO 14001 environmental standards.

Sample Compatibility & Compliance

The TF-FZG-20 accommodates diverse sample formats including bulk trays (up to 2000 × 1000 mm), vials (2R–50R), and custom molds—ideal for viscous extracts such as enzymatically hydrolyzed bird’s nest glycoproteins or concentrated beef gelatin hydrolysates. Its chamber geometry, surface finish, and sealed pneumatic valve actuation meet core hygienic design criteria outlined in EHEDG Doc. 8 and ASME BPE-2022. While not certified to FDA 21 CFR Part 11 out-of-the-box, the system’s data acquisition architecture supports full electronic signature implementation, raw data integrity safeguards, and user-level access control—enabling qualification under GLP, GMP, and HACCP frameworks upon IQ/OQ/PQ validation. Documentation packages include FAT/SAT reports, material traceability records (MTRs), and 3.1 EN 10204 mill certificates for all wetted parts.

Software & Data Management

TFD-5000 is a validated, Windows-based process control platform compliant with IEC 62304 Class B software lifecycle requirements. It provides multi-user role assignment (Operator, Technician, Administrator), real-time trend visualization of shelf temperature, chamber pressure, condenser temperature, and vacuum rate, and automated generation of CSV- and PDF-formatted batch records. All critical events—including alarm triggers, mode transitions, and manual overrides—are timestamped and logged with operator ID. The system supports optional integration with MES/SCADA platforms via OPC UA or Modbus TCP. Software updates are distributed free-of-charge and maintain backward compatibility with historical recipe libraries and archived datasets.

Applications

• Stabilization of thermolabile animal-derived actives: bovine collagen peptides, elastin fragments, and bone marrow-derived growth factors.
• Lyophilization of mucilaginous avian biosources: edible bird’s nest (Aerodramus fuciphagus) extracts rich in sialic acid and epidermal growth factor analogs.
• Production of ready-to-reconstitute functional food intermediates: freeze-dried beef broth powders, hydrolyzed meat protein isolates, and fermented meat peptide concentrates.
• Pharmaceutical excipient manufacturing: sterile-grade gelatin carriers, albumin-based delivery matrices, and lyophilized enzyme formulations.
• R&D scale-up support: bridging laboratory freeze dryers (e.g., Labconco FreeZone) to commercial manufacturing through identical thermal profiles and mass-transfer kinetics.

FAQ

Is the TF-FZG-20 suitable for sterile pharmaceutical manufacturing?
It meets core equipment design requirements for aseptic processing but requires additional validation (e.g., SIP cycle qualification, HEPA filtration integration, and ISO 5 cleanroom enclosure) to comply with Annex 1.
Can shelf temperature be controlled independently per layer?
No—shelves operate in parallel via shared silicone oil circuitry; however, radiant top shelf enables compensation for axial thermal gradient effects.
What vacuum pump configurations are supported?
Standard configuration includes ULVAC (formerly Unisem) high-vacuum roots + scroll pump sets; alternative options include Leybold, Pfeiffer, or Edwards modular assemblies based on throughput and contamination sensitivity.
Does the system support remote monitoring and diagnostics?
Yes—via built-in Ethernet port and optional VPN-enabled secure remote access using TeamViewer IoT or custom SCADA middleware.
What documentation is provided for regulatory submission?
Full DQ/IQ/OQ protocol templates, FAT report, electrical schematics, piping & instrumentation diagrams (P&IDs), and material compliance declarations per RoHS/REACH/CE directives.
