Tianfeng TF-FZG-100 Industrial-Scale Food Freeze Dryer

Overview

The Tianfeng TF-FZG-100 is an industrial-scale vacuum freeze dryer engineered for high-throughput, continuous production of thermolabile food products. It operates on the fundamental principle of sublimation—removing water from frozen material under deep vacuum while maintaining product integrity, morphology, rehydration capacity, and nutritional profile. With a certified effective drying area of 98.68 m², this system is purpose-built for batch processing of bulk commodities including beef, seafood, fruits, vegetables, pet food, instant meals, soluble coffee, and herbal health supplements. Its integrated chamber–cold trap architecture, combined with precision-controlled shelf temperature modulation (−45 °C to +80 °C) and ultra-low cold trap temperature (≤ −65 °C), ensures rapid primary drying kinetics and efficient secondary drying under stable vacuum conditions (≤ 2.7 Pa). The unit complies with core hygienic design tenets outlined in ISO 22000, FDA 21 CFR Part 11 (when paired with validated software configurations), and EU GMP Annex 15 for process validation—making it suitable for facilities operating under HACCP, SQF, or BRCGS-certified quality systems.

Key Features

• Monolithic AISI 304 stainless steel chamber with mirror-finished interior surfaces, zero-weld crevices, and fully drainable geometry—designed to eliminate microbial harborage points and support CIP/SIP readiness.
• Integrated front-chamber/rear-trap layout with dual observation windows equipped with LED illumination, enabling real-time visual monitoring without vacuum interruption.
• Dual-zone thermal control: independently regulated shelf heating/cooling circuits (using silicone oil or glycol thermal fluid) and dedicated cryogenic refrigeration for the condenser—ensuring precise thermal profiling across all drying phases.
• Modular shelf configuration: (15+1) × 2 adjustable shelves (77 mm pitch); optional aluminum extrusion or 304 stainless steel plate variants—both optimized for uniform heat transfer and cleanability.
• High-capacity condensation system: 1500 kg/24 h water removal capacity using corrosion-resistant stainless steel coil manifolds; available in monolithic or segmented cold trap configurations per client site constraints.
• Robust refrigeration package: multi-stage cascade compressors with premium imported components (e.g., Bitzer, Danfoss), delivering rapid cooldown (< 60 min from ambient to −65 °C) and long-term operational stability.
• Omnidirectional vacuum architecture: configurable vacuum pump trains—including ULVAC (formerly Anshun/Ebara) dry scroll and oil-lubricated roots pumps—optimized for low particulate generation and consistent ultimate vacuum performance.

Sample Compatibility & Compliance

The TF-FZG-100 accommodates heterogeneous load geometries—from stacked trays of sliced beef and whole fish fillets to granulated pet kibble and powdered botanical extracts—without compromising drying uniformity. All wetted surfaces meet EC 1935/2004 food contact material requirements. Structural fabrication adheres to ASME BPVC Section VIII Div. 1 (with PED 2014/68/EU compliance documentation available upon request). The system supports validation protocols aligned with ISO 13485 (for nutraceutical applications) and ICH Q5C (for biologically derived food actives). Documentation packages include FAT/SAT reports, IQ/OQ templates, and traceable calibration records for all critical sensors (PT100 shelf thermistors, Pirani/Capacitance vacuum gauges, load cell-based weight monitoring interfaces).

Software & Data Management

Control is executed via an Omron CJ2M PLC platform interfaced with a Windows-based industrial PC running proprietary Tianfeng FreezeDry Pro™ v4.x software. The system supports full 21 CFR Part 11 compliance when deployed with electronic signature modules, audit trail logging, role-based access control, and encrypted data archiving. Up to 99 customizable drying recipes can be stored locally or synchronized over secure Wi-Fi to centralized MES environments. Real-time trending includes shelf temperature differentials, chamber pressure decay rates, condenser loading curves, and sublimation front progression metrics. Data export formats include CSV, PDF batch reports, and OPC UA connectivity for integration into Siemens Desigo, Rockwell FactoryTalk, or Emerson DeltaV infrastructures.

Applications

This freeze dryer serves as a core processing asset in commercial food manufacturing facilities requiring regulatory-compliant dehydration without Maillard browning, enzymatic degradation, or volatile compound loss. Primary use cases include: extended-shelf-life beef jerky and ready-to-eat meal components; nutrient-retentive fruit leathers and vegetable crisps; pathogen-inactivated pet treats meeting AAFCO moisture limits; instant coffee agglomerates preserving aromatic volatiles; and standardized herbal extracts for functional food matrices. It is also deployed in pilot-scale contract manufacturing organizations (CMOs) supporting clinical nutrition trials and novel protein ingredient development (e.g., insect-based or cultivated meat analogs).

FAQ

Is the TF-FZG-100 suitable for GMP-certified food production facilities?
Yes—the chamber, shelves, and cold trap are constructed to GMP hygienic design standards, with full weld mapping, surface roughness Ra ≤ 0.8 µm, and third-party verification reports available.
Can shelf temperature profiles be modified during an active cycle?
Yes—operators may adjust setpoints, hold durations, or skip steps in real time without aborting the batch, provided safety interlocks remain satisfied.
What vacuum pump options are supported for high-humidity feedstock?
We recommend hybrid configurations: dry scroll pre-pumps paired with oil-sealed rotary vane or roots blowers—validated for sustained operation at ≤ 2.7 Pa under 100% saturated vapor loads.
Does the system include remote diagnostics and firmware updates?
Yes—via TLS-secured web interface and optional cellular backup; all diagnostic logs, alarm histories, and sensor drift alerts are accessible through the IPC dashboard.
Are validation support documents included with delivery?
Standard delivery includes FAT protocol, electrical schematics, P&ID diagrams, material certificates (EN 10204 3.1), and IQ/OQ execution checklists—custom URS alignment services are available under separate SOW.
