Tianfeng TF-FZG-2 Industrial-Scale Freeze Dryer

Overview

The Tianfeng TF-FZG-2 is an industrial-scale, in-situ freeze dryer engineered for continuous, high-reproducibility lyophilization of food-grade materials under controlled low-temperature and high-vacuum conditions. It operates on the fundamental principle of sublimation—removing water from frozen product directly from solid to vapor phase without passing through the liquid state—thereby preserving thermolabile compounds, structural integrity, rehydration kinetics, and microbiological stability. Designed for production environments rather than benchtop R&D, the TF-FZG-2 integrates pre-freezing, primary drying, and secondary drying stages within a single chamber, eliminating manual transfer and minimizing contamination risk. Its robust stainless-steel construction, full-shelf heating/cooling capability, and PLC-driven process logic support GMP-aligned manufacturing of pet treats, functional food ingredients, culinary concentrates, and emergency rations.

Key Features

• In-situ freezing and drying: Eliminates inter-stage handling, reduces cross-contamination, and maintains consistent thermal history across batches.
• Hydraulically actuated shelf system with uniform temperature control (±1 °C across 2 m² effective area), enabling precise regulation between −30 °C and +80 °C for optimized ice nucleation, drying rate, and residual moisture control.
• Touchscreen HMI interface with embedded PLC controller providing real-time monitoring of vacuum pressure, shelf temperature, condenser load, and process time—fully compliant with GLP data integrity requirements.
• Integrated Ethernet port supporting remote supervision, historical curve export (CSV/TXT), and synchronized timestamped logging for audit-ready documentation.
• Modular monoblock design facilitates site installation with minimal civil works; footprint optimized for constrained production floor layouts (15 m × 2.5 m base dimension).
• Optional CIP (Clean-in-Place) and SIP (Sterilize-in-Place) compatibility—validated for aqueous cleaning agents and saturated steam up to 121 °C—ensuring repeatable hygiene performance per FDA 21 CFR Part 11 and ISO 22000 protocols.

Sample Compatibility & Compliance

The TF-FZG-2 accommodates diverse organic matrices including raw meat strips, seafood fillets, fruit purees, vegetable slices, herbal extracts, dairy powders, and composite pet snack formulations. Its −35 °C condenser and ≤10 Pa ultimate vacuum ensure efficient water vapor removal from high-moisture or high-volatility substrates. All wetted surfaces meet AISI 304 stainless-steel standards. The system supports validation documentation packages aligned with ISO 9001:2015, ISO 13485 (for medical-grade food supplements), and USP lyophilization guidance. Process parameters are fully traceable for internal quality audits and third-party regulatory inspections.

Software & Data Management

The embedded control software records all critical process variables at user-defined intervals (minimum 1-second resolution), generating time-stamped freeze-drying curves for shelf temperature, chamber pressure, condenser temperature, and elapsed cycle time. Data export complies with ASTM E2500-13 for equipment qualification and supports CSV import into LIMS or MES platforms. Audit trail functionality meets FDA 21 CFR Part 11 requirements—including electronic signatures, user access levels, and immutable log history—for pharmaceutical-grade food manufacturing environments.

Applications

• Pet nutrition: Single-ingredient protein snacks (beef liver, salmon, chicken breast), functional chews (collagen, glucosamine-enriched), and hypoallergenic meal toppers.
• Gourmet food preservation: Dehydrated herbs, mushroom powders, artisanal broth cubes, and flash-frozen fruit compotes retaining volatile aroma profiles.
• Nutritional supplement manufacturing: Stabilized probiotics, enzyme blends, botanical extracts (ginseng, goji, cordyceps), and whey/collagen hydrolysates.
• Emergency and field rations: Lightweight, shelf-stable meals for military, aerospace, maritime, and expeditionary use—meeting MIL-STD-810G thermal cycling and ISTA 3A transport durability benchmarks.
• Food ingredient development: High-value flavor encapsulates, instant coffee granules, tea polyphenol concentrates, and plant-based protein isolates requiring minimal thermal degradation.

FAQ

What is the maximum batch capacity for animal-based pet treats?
Based on standard loading density (6–8 kg/m² for sliced meat), the 2 m² shelf area supports 12–16 kg per cycle—scalable via multi-cycle scheduling.
Can the system be validated for ISO 13485-certified production?
Yes—full IQ/OQ/PQ documentation templates, calibration records, and alarm response logs are provided upon request.
Is nitrogen backfilling supported for oxygen-sensitive products?
Optional integrated nitrogen purge module available with programmable partial pressure control (0.1–1.0 bar).
What maintenance intervals are recommended for the vacuum pump and refrigeration system?
Oil-lubricated rotary vane pumps require oil change every 2,000 operating hours; refrigerant charge verification and condenser coil inspection recommended annually.
Does the controller support recipe management with version control?
Yes—up to 99 user-defined programs with password-protected editing, revision timestamps, and rollback capability.
