Tianfeng TF-FZG-10 Industrial Food Freeze Dryer – 10.5 m² Production-Scale Lyophilization System

Overview

The Tianfeng TF-FZG-10 is an industrial-scale, shelf-type vacuum freeze dryer engineered for high-reliability production of heat-sensitive food and nutraceutical products—including abalone, pet snacks, functional ingredients (e.g., royal jelly, ginseng, bird’s nest), and premium seafood or meat-based formulations. It operates on the fundamental principle of lyophilization: pre-freezing materials at sub-zero temperatures (down to −50 °C), followed by primary drying under deep vacuum (≤2.7 Pa) to enable direct sublimation of ice without passing through the liquid phase. This phase transition preserves molecular integrity, minimizing degradation of thermolabile compounds—such as enzymes, vitamins, polyphenols, and volatile aromatics—while retaining original color, texture, rehydration kinetics, and microbiological stability. Designed for continuous batch processing in GMP-aligned facilities, the system integrates a cylindrical stainless-steel chamber and condenser in a front-chamber/rear-condenser configuration, optimizing spatial efficiency and thermal uniformity across its 10.5 m² total shelf area.

Key Features

• Full GMP-compliant construction: chamber and shelves fabricated from electropolished SUS 304 stainless steel with mirror-finish interior surfaces and zero-hygiene-dead-zone geometry.
• Integrated chamber–condenser architecture with dual-cylindrical design, featuring an observation window with integrated LED illumination for real-time process monitoring.
• Configurable shelf system: standard 7 load-bearing shelves plus 1 radiant top shelf for temperature compensation; optional aluminum extrusion or SUS 304 shelves—both precision-machined for flatness (<0.1 mm deviation) and optimal thermal conductivity.
• High-capacity condenser with clean stainless-steel coil assembly, available in monolithic or modular configurations per client specification.
• Robust refrigeration system utilizing premium imported compressors and components, delivering rapid cooldown (≤90 min from ambient to −65 °C) and stable condenser performance at ≤−65 °C.
• Dual-mode defrost system: programmable steam or immersion-based cycles ensuring complete ice removal and residue-free sanitation between batches.
• Omron PLC-based control architecture with industrial touchscreen IPC, supporting full recipe management, stepwise parameter override during drying, and seamless jump-to-step functionality.

Sample Compatibility & Compliance

The TF-FZG-10 accommodates diverse biological matrices including whole-shell seafood (e.g., abalone, scallops), minced or sliced meats, pet treat formulations (single-protein jerky, organ blends), botanical extracts, and viscous nutraceutical pastes. Its validated operating envelope supports loading depths up to 25 mm per shelf layer while maintaining uniform pressure distribution and vapor flow dynamics. All wetted surfaces comply with FDA 21 CFR Part 11 data integrity requirements when operated with audit-trail-enabled TFD-5000 software. The system conforms to ISO 22000 food safety management principles and meets structural and material prerequisites outlined in EU Annex 1 (Manufacture of Sterile Medicinal Products) for non-sterile food-grade lyophilization environments. Documentation packages include FAT/SAT protocols, IQ/OQ templates, and material traceability records per ISO 9001:2015-certified quality management processes.

Software & Data Management

Control and data acquisition are managed via the proprietary TFD-5000 software suite, installed on an embedded industrial PC with resistive touch interface. The platform enables full-cycle automation—including pre-freeze ramping, primary drying hold points, secondary drying desorption profiles, and endpoint determination via pressure rise test (PRT) or product temperature stabilization logic. All operational parameters (shelf temp, chamber pressure, condenser temp, vacuum pump status, cooling water flow) are logged at user-defined intervals (minimum 1-second resolution) with automatic timestamping and electronic signature support. Data export is compatible with CSV, PDF, and XML formats; raw logs are encrypted and stored locally with optional cloud backup integration. Software updates are provided free-of-charge throughout the equipment lifecycle and maintain backward compatibility with legacy recipe libraries.

Applications

This system serves commercial-scale production needs across three core verticals: (1) Human food—freeze-dried abalone fillets, instant soup bases, gourmet mushroom powders, and ready-to-eat fruit crisps requiring >95% rehydration fidelity within 60 seconds; (2) Pet nutrition—high-protein single-ingredient treats (e.g., duck lung, salmon skin), functional supplements (probiotic-coated kelp granules), and moisture-sensitive chews where enzymatic activity retention is critical; (3) Nutraceutical manufacturing—lyophilized bee pollen capsules, stabilized collagen hydrolysates, and low-bioavailability herbal tinctures reformulated into rapidly dispersible oral powders. Its 200 kg/24h ice capacity supports throughput of ~100 kg finished product per batch, depending on initial solids content and cake structure.

FAQ

Is the TF-FZG-10 suitable for FDA-regulated nutraceutical manufacturing?
Yes—the system’s construction, documentation framework, and software architecture align with FDA expectations for process validation, change control, and electronic record retention under 21 CFR Part 11.
Can shelf temperature uniformity be verified and documented?
Yes—each shelf is equipped with dual calibrated Pt100 sensors; temperature mapping reports (per ASTM E2297) can be generated using optional validation kits.
What vacuum pump options are available?
Standard configuration includes ULVAC or Ebara oil-sealed rotary vane pumps; dry scroll or hybrid turbo-molecular alternatives are available upon request for solvent-laden or oxygen-sensitive applications.
Does the system support automated cleaning-in-place (CIP)?
While not fully CIP-integrated, the chamber and condenser are designed for rapid manual disassembly and feature sloped drainage paths, enabling efficient post-cycle sanitation per Sanitation Standard Operating Procedures (SSOPs).
Is remote monitoring supported?
Yes—via optional Ethernet/IP or Modbus TCP gateway, allowing integration into centralized SCADA or MES platforms for real-time KPI tracking and predictive maintenance alerts.
