Tianfeng TF-FZG-10 Square Meter Industrial Freeze Dryer

Overview

The Tianfeng TF-FZG-10 Square Meter Industrial Freeze Dryer is a purpose-engineered lyophilization system designed for continuous batch processing of heat-sensitive organic materials in food, pet nutrition, herbal medicine, and functional ingredient manufacturing. Operating on the fundamental principle of sublimation—where ice transitions directly from solid to vapor under deep vacuum and controlled thermal conditions—the TF-FZG-10 enables preservation of structural integrity, enzymatic activity, volatile aroma compounds, and bioactive constituents without thermal degradation. Its integrated chamber-and-cold-trap architecture minimizes footprint while maximizing thermal efficiency and process repeatability. Engineered for production-scale operation—not laboratory prototyping—the system supports batch loads up to 100 kg of raw material across 10.5 m² of shelf area, making it suitable for commercial freeze-drying of pet treats, fruit/vegetable crisps, meat-based snacks, botanical extracts, and traditional herbal preparations.

Key Features

• GMP-compliant construction: 304 stainless steel drying chamber with electropolished interior surface (Ra ≤ 0.4 µm), zero dead-leg design, and fully drainable geometry to meet hygiene requirements for food-grade and nutraceutical applications.
• Integrated cold trap with dual-configuration option: either monolithic or modular stainless steel coil condenser, rated for ≤ −65 °C operating temperature and 200 kg/24 h ice capture capacity at ≤ 2.7 Pa ultimate vacuum.
• Thermally optimized shelf system: 8 total plates (7 active + 1 base), spaced at 65 mm intervals; configurable with high-conductivity anodized aluminum or sanitary 304 stainless steel shelves—both engineered for uniform heat transfer and cleanability.
• Robust refrigeration architecture: High-efficiency cascade or single-stage industrial refrigeration circuit utilizing premium imported compressors, ensuring rapid cooldown (< 90 min from ambient to −60 °C) and stable shelf temperature control (±0.5 °C).
• Advanced process control: Omron CJ2M series PLC coupled with industrial touch-panel IPC; supports multi-step recipe programming, real-time parameter logging, remote monitoring via encrypted Wi-Fi, and audit-trail-enabled operation compliant with GLP documentation practices.
• Hygienic auxiliary systems: Optional steam or hot-water defrost cycle; front-loading door with silicone-sealed viewport and integrated LED illumination; CIP-compatible drainage ports and sloped internal surfaces.

Sample Compatibility & Compliance

The TF-FZG-10 accommodates diverse sample forms including sliced meats (e.g., chicken breast, beef liver), whole small aquatic species (shrimp, sardines), powdered botanicals (ginseng, cordyceps), liquid concentrates (fruit juices, enzyme solutions), and soft-moist pet foods (egg yolk paste, minced organ blends). Its chamber geometry and plate loading configuration support both tray-based and bulk-bin drying formats. All wetted surfaces comply with FDA 21 CFR Part 117 (Current Good Manufacturing Practice for Food), ISO 22000:2018 food safety management requirements, and EU Regulation (EC) No 1935/2004 for materials in contact with foodstuffs. Documentation packages include material traceability records, weld maps, surface roughness reports, and third-party pressure vessel certification where applicable.

Software & Data Management

The embedded IPC runs proprietary Tianfeng LyoControl™ v4.2 software, supporting full-cycle automation from pre-freezing through primary and secondary drying to final desorption hold. Each batch generates timestamped CSV and PDF log files containing shelf temperature, chamber pressure, condenser temperature, vacuum pump status, and power consumption—exportable via USB or network share. User access levels are role-defined (Operator, Technician, Administrator), with password protection and electronic signature capability for critical actions (e.g., recipe upload, manual step override). Audit trail functionality meets basic ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available), facilitating internal quality reviews and regulatory readiness for USDA-FSIS or BRCGS audits.

Applications

• Pet nutrition: Production of shelf-stable, high-protein treats such as freeze-dried duck lung, turkey necks, salmon skin chips, and insect-based kibble supplements—retaining digestibility and palatability without binders or preservatives.
• Fruit & vegetable processing: Preservation of delicate produce (strawberries, raspberries, kale, shiitake) with >95% retention of vitamin C, anthocyanins, and fiber morphology.
• Herbal & nutraceutical manufacturing: Stabilization of thermolabile actives in Rehmannia glutinosa, Maca root, and Cordyceps sinensis extracts; compatible with USP Chapter <561> lyophilization guidance for botanical drug substances.
• Functional food development: Preparation of instant soup bases, probiotic powders, and collagen hydrolysate granules requiring low-residual moisture (< 2.5% w/w) and long-term ambient storage stability.

FAQ

Is the TF-FZG-10 suitable for pharmaceutical-grade lyophilization?
No—it is engineered and validated for food, pet food, and nutraceutical applications under GMP-aligned but non-sterile manufacturing conditions. It does not include sterilizable SIP/CIP cycles, HEPA-filtered nitrogen backfill, or PAT-integrated sensors required for cGMP pharmaceutical use.
Can shelf temperature be independently controlled per layer?
No—shelves operate in uniform thermal zones; however, the system supports gradient ramping across stages (e.g., −40 °C hold → +20 °C ramp → +60 °C desorption) with programmable rate limits.
What vacuum pump configurations are available?
Standard fitment includes ULVAC or Ebara oil-lubricated rotary vane pumps; optional dry scroll or hybrid turbomolecular-pump packages are available for solvent-rich or oxygen-sensitive processes.
Does the system support IQ/OQ documentation?
Yes—Tianfeng provides template protocols and factory-verified test data (temperature mapping, vacuum leak rate, condenser capacity verification) for user-executed qualification under ISO 9001:2015 and ICH Q5C guidelines.
What maintenance intervals are recommended for the refrigeration system?
Compressor oil analysis every 2,000 operating hours; refrigerant charge verification annually; cold trap coil inspection and passivation every 12 months—per OEM service manual and ASHRAE Guideline 3-2021.
