BIOCOOL LYO-10SE Production-Scale Freeze Dryer

Overview

The BIOCOOL LYO-10SE is a production-scale shelf-type freeze dryer engineered for reproducible, scalable lyophilization of heat-sensitive biopharmaceuticals, herbal extracts, functional foods, and advanced materials. It operates on the fundamental principle of sublimation under deep vacuum: frozen water is removed directly from the solid phase to vapor without passing through the liquid state, preserving structural integrity, biological activity, and chemical stability. Designed for continuous batch processing in pilot and small-to-medium manufacturing environments, the LYO-10SE integrates robust refrigeration architecture, precision vacuum regulation, and programmable process control to meet the stringent requirements of process validation and quality-by-design (QbD) frameworks. Its 10 m² drying area supports up to 33,600 vials (Ø22 mm), making it suitable for clinical trial material production, GMP-aligned process development, and commercial-scale botanical or nutraceutical lyophilization where regulatory traceability and operational consistency are critical.

Key Features

• Shelf-based pre-freezing capability enables uniform thermal conditioning prior to primary drying—eliminating reliance on external ultra-low temperature freezers.
• Programmable multi-stage drying control with automated endpoint detection during desorption drying, based on real-time product temperature and pressure rise analysis.
• Vacuum modulation system dynamically adjusts chamber pressure during both primary and secondary drying to suppress boiling, collapse, or foaming in sensitive formulations—including protein solutions, liposomal suspensions, and viscous botanical concentrates.
• Pulse backfill system with three selectable rates (slow/medium/fast) ensures gentle inert gas (N₂ or argon) reintroduction—minimizing particle displacement and active ingredient loss in porous, fibrous, or low-density dried cakes.
• Hermetically welded stainless steel shelves (316L) with integrated fluid circulation channels provide ±0.5 °C temperature uniformity across the entire 10 m² surface, validated per ISO 13485 Annex A and ASTM F2373.
• Industrial-grade 10.4-inch touchscreen HMI with intuitive workflow navigation; no manual reference required for routine operation or protocol recall.
• Integrated calibration functions for shelf temperature sensors and capacitance manometers, supporting periodic verification per ISO/IEC 17025 requirements.
• Real-time monitoring of shelf temperature, condenser temperature, chamber pressure, and refrigerant pressures at 50 ms sampling intervals—ensuring high-fidelity process data capture.

Sample Compatibility & Compliance

The LYO-10SE accommodates diverse sample formats including glass vials (Ø22 mm, up to 33,600 units/batch), serum bottles, trays, and custom containers mounted on its 9+1 adjustable shelves. It supports aqueous, alcoholic, and low-concentration organic solvent systems when equipped with an optional solvent trap. While the economic variant does not include CIP/SIP capabilities, its construction adheres to ASME BPE-2023 surface finish standards (Ra ≤ 0.8 µm on wetted parts) and complies with CE Machinery Directive 2006/42/EC and PED 2014/68/EU. The system meets essential prerequisites for GLP-compliant process development and satisfies baseline requirements for FDA 21 CFR Part 11–ready data integrity when paired with optional audit-trail-enabled software modules.

Software & Data Management

The embedded control system stores up to 2000 fully parameterized lyophilization protocols—each containing time-temperature-pressure profiles, ramp rates, hold durations, and endpoint logic. All process data—including shelf temperature curves, chamber pressure trends, and condenser load dynamics—are timestamped and exportable in CSV or XML format. Optional PC-based remote monitoring extends oversight up to 1.5 km via Ethernet or fiber-optic link, enabling centralized supervision across multiple units. When configured with the Process Data Recording Module (optional), the system generates ALCOA+ compliant electronic records aligned with Annex 11 principles, including electronic signatures, change history, and secure user access levels.

Applications

• Lyophilization of monoclonal antibodies, vaccines, and recombinant proteins under controlled nucleation conditions.
• Stabilization of traditional Chinese medicine (TCM) extracts, enzyme-rich botanicals, and probiotic cultures.
• Production of instant functional food powders (e.g., matcha, spirulina, collagen peptides) with minimized oxidation and flavor degradation.
• Drying of nanostructured hydrogels, aerogel precursors, and porous ceramic suspensions for materials science R&D.
• Manufacture of feed-grade enzymes, vitamins, and microbial inoculants requiring long-term ambient storage stability.
• Development of lyophilized diagnostic reagents and lateral flow assay components with batch-to-batch consistency.

FAQ

Does the LYO-10SE support Good Manufacturing Practice (GMP) compliance?
It meets foundational GMP infrastructure requirements (material traceability, calibration capability, data logging) but lacks integrated CIP/SIP—making it appropriate for non-sterile process development and clinical manufacturing under quality oversight, rather than final commercial sterile fill-finish.
What vacuum pump options are compatible with this system?
Standard configuration includes an oil-lubricated dual-stage rotary vane pump; optional upgrades include dry scroll pumps and expanded vacuum train configurations for aggressive solvent removal.
Can shelf temperature be ramped linearly or stepwise during primary drying?
Yes—the controller supports both linear ramps and discrete step transitions, with programmable rate limits and hold conditions at each setpoint.
Is eutectic point determination supported natively?
Eutectic point testing is available as an optional add-on module, utilizing integrated product resistance measurement and comparative freezing curve analysis.
How is long-term sensor drift mitigated?
Onboard temperature and pressure sensors feature user-accessible calibration routines, allowing field verification against NIST-traceable references at defined intervals per internal SOPs.
