BioCool LYO-20E Production-Scale Freeze Dryer

Overview

The BioCool LYO-20E is a production-scale, shelf-type freeze dryer engineered for reproducible, GMP-aligned lyophilization of pharmaceuticals, biologics, nutraceuticals, and high-value food ingredients. It operates on the fundamental principles of sublimation under deep vacuum and controlled heat transfer—where frozen water is removed directly from the solid phase to vapor without passing through liquid, preserving thermolabile structures, enzymatic activity, and structural integrity of sensitive biomolecules. Designed for batch processing in pilot and small-to-medium manufacturing environments, the LYO-20E delivers 20 m² of uniform shelf surface area, enabling scalable lyophilization of vials, trays, and bottles (e.g., up to ~42,900 units of Ø22 mm vials per cycle). Its robust architecture integrates a high-efficiency cascade refrigeration system with a condenser operating below −75 °C, ensuring rapid ice capture and stable vacuum conditions (<4 Pa) throughout primary and secondary drying stages.

Key Features

• Programmable PLC-based control system supporting fully automated cycles—from pre-freezing and primary drying to desorption, endpoint detection, and inert gas backfilling.
• Shelf temperature control range of −55 °C to +110 °C with ±0.5 °C uniformity across all shelves; optimized for both cryo-stabilization and controlled heat input during drying.
• Triple-mode pulse backfill system (slow/medium/fast) for nitrogen or inert gas reintroduction—minimizing particle dispersion and active ingredient loss in fragile amorphous or fibrous dried products.
• Real-time vacuum regulation during sublimation and desorption phases to suppress boiling, foaming, or container deformation—critical for formulations containing surfactants, polymers, or organic solvents.
• Automated endpoint determination via product temperature and pressure rise test (PRT), verifying residual moisture levels meet target specifications (e.g., ≤1–3% w/w per USP & Ph. Eur. guidelines).
• Welded stainless-steel shelf construction with zero leakage—validated per ISO 13485-compliant leak testing protocols and compatible with cleanroom Class C/D environments.
• Industrial-grade HMI touchscreen interface with intuitive navigation, multilingual support (English default), and embedded help context—requiring no external documentation for routine operation.
• Comprehensive data logging at 50 ms intervals for shelf temperature, condenser temperature, chamber pressure, and vacuum pump status—exportable in CSV or PDF format for audit trails.

Sample Compatibility & Compliance

The LYO-20E accommodates diverse sample formats including glass vials (Ø22 mm, up to 42,900 units/cycle), aluminum trays, serum bottles, and custom containers mounted on its 11+1 shelf configuration. Its design supports lyophilization of aqueous, buffered, and low-concentration biopolymer solutions—including monoclonal antibodies, vaccines, probiotics, herbal extracts, enzyme preparations, and nanostructured delivery systems. While the economic variant does not include Clean-in-Place (CIP) or Steam-in-Place (SIP) functionality, it conforms to core mechanical and electrical safety standards (IEC 61000-6-2/6-4, GB/T 14710), and its process data architecture supports alignment with 21 CFR Part 11 requirements when paired with optional electronic signature and audit trail modules. All temperature and vacuum sensors are field-calibratable to ensure long-term metrological traceability per ISO/IEC 17025 recommendations.

Software & Data Management

The integrated control software provides full-cycle recipe management—storing up to 2000 programmable protocols with versioning, parameter locking, and user-level access permissions. Each run generates a timestamped, tamper-evident log file containing all critical process variables, alarms, and operator actions. Optional PC remote monitoring enables real-time visualization and alarm notification over Ethernet or fiber-optic links up to 1.5 km—ideal for centralized facility control rooms. Data export complies with ASTM E2500-13 and ISPE Baseline Guide Vol. 4 for process validation documentation. For regulated environments, optional add-ons include electronic signatures, role-based authentication, and FDA 21 CFR Part 11-compliant audit trails with immutable event logs.

Applications

The LYO-20E serves as a workhorse platform for process development and commercial-scale lyophilization in multiple regulated and non-regulated sectors: sterile biopharmaceutical manufacturing (vaccines, plasma derivatives); traditional Chinese medicine (TCM) concentrate drying; functional food ingredient stabilization (probiotics, peptides, anthocyanins); specialty feed additives (enzymes, vitamins); and advanced material synthesis (porous silica nanoparticles, lyophilized catalysts). Its thermal stability and vacuum precision make it suitable for drying formulations containing volatile co-solvents—when used with the optional organic solvent trap and dry vacuum pump configuration.

FAQ

Is the LYO-20E compliant with GMP or FDA requirements?
The LYO-20E is an economic-grade production freeze dryer and does not include CIP/SIP or full 21 CFR Part 11 compliance out-of-the-box. However, its hardware architecture supports integration of qualified validation packages, calibration records, and electronic audit trails via optional modules.
What is the maximum batch capacity in standard vials?
Using Ø22 mm vials with standard spacing, the unit accommodates up to 42,900 units per batch across its 20 m² shelf area.
Can the system handle organic solvent-containing formulations?
Yes—when equipped with the optional solvent trap and dry vacuum pump, the LYO-20E safely condenses methanol, ethanol, acetone, and other low-boiling-point solvents during primary drying.
Does the system support IQ/OQ/PQ documentation support?
BioCool provides vendor-supplied IQ/OQ templates and on-site PQ assistance (travel and labor billed separately); full qualification requires client-specific risk assessment and protocol approval.
What maintenance intervals are recommended for long-term reliability?
Vacuum pump oil change every 500 operational hours; condenser coil inspection quarterly; temperature and vacuum sensor calibration annually—or per internal quality schedule aligned with ISO/IEC 17025.
