Tianfeng TF-FZG-20 Industrial-Scale Freeze Dryer for Fruits, Vegetables, Meat (e.g., Chicken Breast), and Herbs (e.g., Goji Berries)

Overview

The Tianfeng TF-FZG-20 is an industrial-scale, shelf-type freeze dryer engineered for continuous, high-throughput lyophilization of heat-sensitive food matrices—including poultry (e.g., chicken breast), vegetables, fruits, marine products, herbal materials (e.g., goji berries), functional food powders, pet nutrition formulations, and ready-to-eat meal components. Operating on the fundamental principle of sublimation—where ice is removed directly from frozen product under deep vacuum without passing through the liquid phase—the system ensures minimal thermal degradation, preservation of volatile compounds, enzymatic activity suppression, and structural integrity retention. Designed explicitly for production environments rather than pilot or laboratory use, the TF-FZG-20 meets core engineering requirements for scalability, process repeatability, and regulatory traceability in food manufacturing settings compliant with HACCP, ISO 22000, and GMP-aligned facility standards.

Key Features

• GMP-compliant chamber construction: Cylindrical main chamber fabricated from AISI 304 stainless steel with mirror-finish internal surface (Ra ≤ 0.4 µm), eliminating microbial harborage points and enabling effective clean-in-place (CIP) procedures.
• Integrated front-chamber/rear-cold-trap architecture: Compact monoblock layout reduces footprint while optimizing vapor flow path efficiency and minimizing condensation losses; includes dual-pane observation window with integrated LED illumination for real-time visual monitoring.
• Modular shelf system: 11 total shelves (10 operational + 1 auxiliary), configurable in either extruded aluminum (high thermal conductivity, uniform heat transfer) or 304 stainless steel (enhanced cleanability, corrosion resistance); standard spacing of 70 mm accommodates stacked trays or bulk loading.
• High-capacity refrigeration: Dual-stage cascade refrigeration system using premium imported compressors achieves cold trap temperatures ≤ −65 °C and supports rapid freezing ramp rates, critical for eutectic point control in heterogeneous food matrices.
• Robust vacuum generation: Equipped with ULVAC (formerly Anshin/Edwards) high-efficiency vacuum pump assemblies capable of sustaining ≤ 2.7 Pa ultimate pressure across full load conditions; optional multi-pump configurations available for extended batch durations or high-moisture-content feedstocks.
• Intelligent process control: Omron CJ2M-series PLC paired with industrial touchscreen IPC enables recipe-based automation, real-time parameter logging (shelf temp, chamber pressure, condenser temp, time), audit-trail-enabled operation history, and remote diagnostics via encrypted Wi-Fi or Ethernet.

Sample Compatibility & Compliance

The TF-FZG-20 accommodates diverse physical forms—whole cuts, diced pieces, purees, slurries, and liquid concentrates—across moisture content ranges typical of minimally processed foods (e.g., 70–90% initial water content in fresh chicken breast or goji berries). Its shelf temperature range (−45 °C to +80 °C) supports both primary drying (sublimation-controlled) and secondary drying (desorption-controlled) phases without hardware modification. All wetted surfaces comply with FDA 21 CFR Part 110 (Current Good Manufacturing Practice in Manufacturing, Packing, or Holding Human Food) and EC No. 1935/2004 (Materials and Articles Intended to Come into Contact with Food). Documentation packages include material certifications (EN 10204 3.1), weld maps, surface roughness reports, and FAT/SAT protocols per ISO 9001:2015 quality management system certification held by Tianfeng.

Software & Data Management

The embedded IPC runs proprietary lyophilization control software supporting ≥ 99 user-defined drying cycles, each with up to 20 programmable steps (ramp/hold profiles for shelf temperature, pressure setpoints, and valve sequencing). All process variables are sampled at 1 Hz and stored locally with timestamped metadata (operator ID, batch ID, cycle version). Export formats include CSV and PDF for integration into LIMS or MES platforms. Audit trails record all parameter changes, manual interventions, login/logout events, and system alarms—fully compliant with ALCOA+ data integrity principles. Remote access allows authorized personnel to monitor live trends, download historical logs, or initiate emergency shutdowns via secure TLS-encrypted connections.

Applications

• Preservation of nutritional profile in lean proteins: Enables shelf-stable chicken breast with <5% residual moisture, retained myofibrillar protein functionality, and negligible lipid oxidation.
• Stabilization of phytochemical-rich botanicals: Maintains anthocyanin, polysaccharide, and flavonoid integrity in goji berries and other functional herbs without solvent exposure or thermal denaturation.
• Production of instant rehydratable vegetable powders: Achieves >95% reconstitution ratio and color fidelity in carrot, spinach, and bell pepper derivatives.
• Development of clean-label pet food ingredients: Delivers pathogen-reduced, low-water-activity meat meals and fish hydrolysates meeting AAFCO nutrient profiles.
• Manufacturing of ready-to-hydrate soup bases and meal kits: Ensures consistent texture, flavor release kinetics, and microbiological safety (<1 CFU/g post-lyo) across commercial batches.

FAQ

Is the TF-FZG-20 suitable for pharmaceutical or biologics applications?
No. This model is designed and validated exclusively for food-grade processing per ISO 22000 and HACCP frameworks—not for sterile or aseptic pharmaceutical manufacturing requiring ISO 5 cleanroom integration or SIP capability.
Can shelf temperature be controlled independently per layer?
No. All shelves operate in uniform thermal mode; independent zone control is not implemented in this configuration.
What validation documentation is provided with shipment?
Each unit ships with Factory Acceptance Test (FAT) report, IQ/OQ summary, material traceability dossiers, and calibration certificates for integrated PT100 sensors and capacitance manometers.
Does the system support automated pressure rise test (PRT) functionality?
Yes. Built-in PRT logic executes leak-rate quantification during hold phases using chamber pressure decay analysis per ASTM F2096–18 guidelines.
Is steam sterilization of the chamber supported?
No. The system is not rated for SIP (steam-in-place); cleaning is performed via validated CIP protocols using food-grade sanitizers.
