Tianfeng TF-FZG-10㎡ Industrial-Scale Freeze Dryer

Overview

The Tianfeng TF-FZG-10㎡ Industrial-Scale Freeze Dryer is a vacuum-based lyophilization system engineered for continuous, high-capacity production of thermolabile materials. Operating on the fundamental principles of sublimation—where frozen water is removed directly from the solid phase to vapor under deep vacuum—the system maintains product integrity by avoiding liquid-phase transition and minimizing thermal degradation. Designed for GMP-aligned manufacturing environments, it supports batch processing of up to 100 kg per cycle across a total shelf area of 10.5 m². Its cylindrical SUS 304 chamber ensures structural rigidity, corrosion resistance, and compliance with hygienic design standards required in food, nutraceutical, and bioprocessing applications. The integrated BITZER semi-hermetic compressor and BAOSI vacuum pump deliver stable deep-vacuum performance down to ≤2.7 Pa, while the condenser achieves a final operating temperature of ≤−60 °C—critical for efficient ice trapping during extended drying cycles.

Key Features

• Production-grade architecture with 10.5 m² stainless steel shelf surface, optimized for uniform heat transfer and scalable loading.
• Dual-range shelf temperature control (−45 °C to +80 °C), enabling precise primary drying, annealing, and secondary drying protocols.
• High-efficiency condenser with ≥200 kg/24 h ice-trapping capacity, reducing downtime between batches and supporting multi-shift operation.
• Omron PLC-based control system with microprocessor interface, offering programmable drying profiles, real-time parameter logging, and alarm management.
• Robust mechanical design: fully welded SUS 304 cylindrical chamber, reinforced door sealing, and vibration-damped mounting for long-term operational stability.
• Comprehensive electrical integration: 60 kW total load at 380 V / 50 Hz / 3-phase, compliant with IEC 60204-1 industrial safety standards.

Sample Compatibility & Compliance

The TF-FZG-10㎡ accommodates heterogeneous sample formats including trays of cut fruit, pre-filled vials of functional extracts, bulk pet food pellets, freeze-concentrated broths, and herbal decoctions. Its wide shelf temperature range and adjustable vacuum ramping support both simple dehydration and complex multi-stage lyophilization cycles required for sensitive bioactive compounds. The system meets ISO 9001:2015 quality management requirements and incorporates design elements aligned with FDA 21 CFR Part 11 data integrity expectations—including audit-trail-capable event logging and user-access-controlled parameter modification. While not certified for sterile pharmaceutical use out-of-the-box, its SUS 304 construction, smooth internal welds, and clean-in-place (CIP)-compatible geometry facilitate validation for food-grade and dietary supplement manufacturing under HACCP and GMP frameworks.

Software & Data Management

The embedded control interface provides intuitive navigation through preconfigured drying templates and custom profile creation. All process variables—including shelf temperature, chamber pressure, condenser temperature, and elapsed time—are sampled at 1-second intervals and stored internally with timestamped metadata. Export options include CSV and PDF report generation via USB port. Optional Ethernet connectivity enables remote monitoring and integration into centralized SCADA or MES platforms. Data security follows ALCOA+ principles: attributable, legible, contemporaneous, original, accurate, complete, consistent, enduring, and available—supporting traceability during regulatory audits. Firmware updates are performed offline to preserve system integrity and avoid network exposure.

Applications

This freeze dryer serves diverse industrial sectors requiring preservation of volatile compounds, enzymatic activity, or structural morphology. In food processing, it produces shelf-stable fruit powders, instant soup bases, and functional pet treats without added preservatives. Nutraceutical manufacturers utilize it for stabilizing probiotics, plant enzymes, and phytochemical concentrates. Traditional Chinese medicine producers apply it to dried herbal slices and concentrated decoctions where volatile oil retention is critical. Additionally, it supports R&D-scale process development for pilot-to-production scale-up, especially when paired with Tianfeng’s complementary cold chain infrastructure—such as ultra-low temperature freezers and precision chillers—for end-to-end thermal management.

FAQ

Is the TF-FZG-10㎡ suitable for pharmaceutical-grade sterile manufacturing?
No—it is designed for food, supplement, and industrial bioproduct applications. Sterile processing requires additional isolator integration, HEPA filtration, and validation per ISO 13408; these are not included.
Can shelf temperature be controlled independently per layer?
No—shelves operate in uniform thermal zones. For differential control, consult Tianfeng’s custom-engineered multi-zone variant (TF-FZG-10MZ).
What maintenance intervals are recommended for the BITZER compressor and vacuum pump?
Compressor oil and filter replacement every 4,000 operating hours; vacuum pump oil change every 500 hours or per BAOSI service guidelines.
Does the system support automated defrosting of the condenser?
Yes—programmable defrost cycles can be scheduled within the PLC interface, with automatic pressure venting and condensate drainage sequencing.
Is IQ/OQ documentation provided with shipment?
Standard delivery includes Factory Acceptance Test (FAT) reports and mechanical completion certificates. User-defined IQ/OQ protocols and on-site qualification support are available as optional services.
