BIOCOOL LYO-7 Production-Scale Freeze Dryer

Overview

The BIOCOOL LYO-7 is a GMP-compliant, production-scale vacuum freeze dryer engineered for reproducible, scalable lyophilization of pharmaceuticals, biologics, and high-value industrial formulations. It operates on the fundamental principle of sublimation—removing water from frozen samples under deep vacuum while maintaining product integrity through precise thermal control of shelf and condenser systems. Designed for continuous batch processing in regulated environments, the LYO-7 integrates structural compliance with functional robustness: its chamber conforms to ASME BPVC Section VIII Div. 1 and PED 2014/68/EU pressure vessel standards, and its full-range pressure tolerance (−0.15 MPa to +0.5 Pa) supports both deep vacuum drying and controlled inert gas backfilling. The system’s architecture enables seamless transition from laboratory process development to commercial manufacturing, supporting validation protocols required by FDA, EMA, and NMPA.

Key Features

• Shelf pre-freezing capability with ±1.0 °C uniformity across the 7 m² stainless-steel shelf surface (9 shelves, 1900 × 1200 mm per shelf), fabricated via orbital TIG welding and certified leak-free for three years.
• Programmable freeze-drying control system with 2000 user-defined or factory-stored cycle recipes; each cycle includes ramp-rate control, hold steps, vacuum modulation, and automatic endpoint detection based on product temperature and pressure rise test (PRT).
• Triple-stage vacuum regulation system: dynamic control during primary drying (sublimation) and secondary drying (desorption) to suppress boiling, collapse, or vial deformation—especially critical for protein-based therapeutics and amorphous formulations.
• Pulse-controlled inert gas backfill system with selectable slow/medium/fast modes, minimizing particle dispersion during repressurization of sensitive lyophilized powders or granules.
• Integrated CIP (Clean-in-Place) and SIP (Steam-in-Place) systems compliant with ISO 13408-1 and EU Annex 1: CIP employs German-sourced liquid ring pumps for residual moisture removal; SIP utilizes pulsed vacuum steam sterilization with Fo-value logging, triple overpressure protection, and real-time temperature mapping up to 150 °C.
• Industrial-grade 15.6″ HMI touchscreen interface with 50 ms data acquisition frequency for shelf temperature, condenser temperature, chamber pressure, and vacuum level—enabling real-time trending and deviation alerts.
• FDA 21 CFR Part 11–compliant process control software featuring electronic signatures, audit trails, role-based access, and immutable electronic records for all operational events and parameter changes.

Sample Compatibility & Compliance

The LYO-7 accommodates standard pharmaceutical vials (∅22 mm, up to 15,750 units per batch), serum bottles, trays, and custom containers. Its chamber geometry—featuring mirror-polished 316L stainless steel surfaces, zero-radius internal corners, and sloped floor design—meets stringent CIP/SIP drainage requirements per USP and WHO TRS 986 Annex 2. All wetted components are electropolished to Ra ≤ 0.4 µm and helium-leak tested to ≤1 × 10⁻⁹ mbar·L/s. Structural certification includes X-ray radiographic inspection of all welds and hydrostatic testing at 1.5× design pressure. The system satisfies GMP Annex 1 (2022), ISO 22000, and ICH Q5C stability testing prerequisites.

Software & Data Management

The embedded control system runs on a deterministic real-time OS with redundant storage (SSD + SD card). Process data—including shelf temperature profiles, chamber pressure curves, condenser load, and PRT results—are timestamped, encrypted, and exportable in CSV/PDF formats. Optional add-ons include Ethernet/IP and OPC UA connectivity for MES/SCADA integration, as well as remote monitoring via secure web portal (up to 1.5 km line-of-sight range). Calibration management tools support traceable NIST-traceable verification of PT100 shelf sensors and capacitance manometers, with calibration logs retained within the audit trail.

Applications

• Pharmaceutical manufacturing: terminal sterilization-compatible lyophilization of monoclonal antibodies, vaccines, and sterile APIs.
• Biotechnology: stabilization of cell therapies, viral vectors, and exosome preparations requiring low residual moisture (<1.0 wt%) and minimal structural denaturation.
• Food & nutraceuticals: preservation of probiotics, enzymes, and heat-labile botanical extracts without Maillard reaction or oxidation.
• Diagnostic reagents: formulation of stable, room-temperature-storable ELISA kits and lateral flow assay components.
• Academic & contract manufacturing: scalable process transfer from pilot-scale (e.g., LYO-2/LYO-5) to commercial batches under identical critical process parameters (CPPs).

FAQ

What regulatory standards does the LYO-7 meet for pharmaceutical use?
The LYO-7 complies with ASME BPVC Section VIII Div. 1, PED 2014/68/EU, ISO 13408-1, EU GMP Annex 1 (2022), and FDA 21 CFR Part 11. Its design basis supports qualification per IQ/OQ/PQ and validation per ASTM F2476 and USP .
Is the system suitable for organic solvent-based formulations?
Yes—when equipped with the optional organic solvent trap and cascade refrigeration unit, the LYO-7 safely handles acetone, ethanol, and tert-butanol-based formulations with condenser capacity extended to −85 °C.
Can process data be exported for regulatory submission?
All raw process data—including time-stamped temperature, pressure, and vacuum traces—are stored in tamper-evident binary format and exportable as PDF reports or CSV files with embedded digital signatures and audit trail metadata.
What maintenance and validation support is provided?
BIOCOOL provides 12-month parts-and-labor warranty, on-site installation and operator training, lyophilization process optimization using customer-supplied samples, and lifetime technical support (fee-based post-warranty). IQ/OQ documentation packages and calibration certificates are supplied with delivery.
