BIOCOOL LYO-3SE Production-Scale Freeze Dryer

Overview

The BIOCOOL LYO-3SE is a production-scale, shelf-type vacuum freeze dryer engineered for robust, repeatable lyophilization of heat-sensitive biopharmaceuticals, herbal extracts, functional foods, and advanced materials. It operates on the fundamental principle of sublimation—removing water from frozen samples under deep vacuum while maintaining product integrity through precise thermal control. Unlike laboratory benchtop units, the LYO-3SE is designed for continuous batch processing in pilot and small-scale manufacturing environments, supporting GMP-aligned workflows with scalable process reproducibility. Its architecture integrates industrial-grade refrigeration, high-efficiency vacuum generation, and programmable shelf temperature control to meet the stringent requirements of process validation, stability studies, and regulatory documentation.

Key Features

• Programmable freeze-drying control system enabling fully automated cycles—from pre-freezing and primary drying to secondary drying and controlled inert gas backfilling.
• Shelf pre-freezing capability with temperature range of −55 °C to +110 °C, ensuring uniform sample solidification prior to primary drying.
• Triple-speed pulse backfill system (slow/medium/fast) for nitrogen or inert gas reintroduction, minimizing particle dispersion during final chamber pressurization.
• Vacuum regulation module permitting dynamic pressure control during both sublimation and desorption phases—critical for preventing boil-over, collapse, or vial breakage in sensitive formulations.
• Advanced end-point detection algorithm that automatically initiates endpoint testing during desorption drying, verifying residual moisture content against user-defined thresholds.
• Welded stainless-steel shelves fabricated via certified orbital welding, guaranteeing zero leakage and compliance with cleaning validation prerequisites.
• Industrial 10.4-inch HMI touchscreen interface with intuitive navigation, real-time parameter visualization, and built-in help prompts—requiring no external manual for routine operation.
• Data acquisition at 50 ms intervals for shelf temperature, condenser temperature, and chamber pressure—supporting high-fidelity process mapping and deviation analysis.
• Onboard storage for up to 2000 customizable or factory-default lyo protocols, including time-temperature-pressure profiles and alarm setpoints.

Sample Compatibility & Compliance

The LYO-3SE accommodates vials (Φ22 mm), trays, and open containers across diverse matrices—including aqueous protein solutions, botanical concentrates, probiotic suspensions, nanocellulose dispersions, and enzyme-loaded microspheres. Its design conforms to core mechanical safety standards (IEC 61000-6-2/6-4, EN 61000-3-2) and supports integration into GLP/GMP environments when configured with optional audit-trail-capable software modules. While the base model meets general pharmaceutical and food-grade production needs, it does not include CIP/SIP functionality—making it suitable for non-sterile manufacturing or post-lyophilization packaging operations. Optional upgrades such as organic solvent traps, cascade compressor systems, and dry vacuum pumps extend compatibility with volatile excipients and low-boiling solvents.

Software & Data Management

Standard firmware includes real-time curve plotting (shelf temp, condenser temp, chamber pressure), historical protocol recall, and freeze-dry curve export in CSV format. Optional PC-based remote monitoring enables supervisory oversight within a 1.5 km radius via Ethernet or RS485 communication—ideal for multi-unit facilities with centralized control rooms. Calibration functions for shelf sensors and Pirani/Penning vacuum gauges ensure metrological traceability over extended operational life. When paired with validated data logging software (sold separately), the system supports 21 CFR Part 11-compliant electronic records—including user authentication, change history, and digital signature capture—facilitating FDA inspection readiness and internal quality audits.

Applications

• Biopharmaceutical development: Stabilization of monoclonal antibodies, vaccines, and diagnostic reagents.
• Traditional Chinese medicine (TCM) processing: Preservation of active alkaloids and glycosides without thermal degradation.
• Functional food manufacturing: Encapsulation of probiotics, vitamins, and polyphenol-rich plant extracts.
• Nanomaterial synthesis: Drying of colloidal silver, silica nanoparticles, and liposomal carriers without aggregation.
• Feed additive production: Lyophilization of microbial cultures, enzymes, and mycotoxin-binding agents.
• Flavor & fragrance industry: Stabilization of volatile aroma compounds and natural essential oil emulsions.

FAQ

What is the difference between the LYO-3SE and standard GMP-compliant freeze dryers?
The LYO-3SE is an economic production model optimized for cost-effective scale-up; it lacks integrated CIP (Clean-in-Place) and SIP (Steam-in-Place) systems, limiting its use to non-sterile or terminal sterilization workflows.
Can the LYO-3SE handle organic solvents like ethanol or acetone?
Yes—with the optional organic solvent trap and upgraded cold trap configuration, the system safely condenses low-boiling solvents during primary drying.
Is temperature calibration traceable to NIST or other national standards?
Calibration routines are supported internally; users may perform field verification using certified reference probes—full traceability requires third-party certification services.
What is the maximum allowable load per cycle based on 3 m² shelf area?
Using standard Φ22 mm vials at 5 mL fill volume and 10 mm spacing, the unit accommodates approximately 6,300 vials per batch.
Does the system support automated recipe transfer between instruments?
Yes—protocol files can be exported/imported via USB drive, enabling consistent method deployment across multiple LYO-series units.
