BIOCOOL LYO-F Series Pharmaceutical-Grade Freeze Dryer for Food, Nutraceuticals & Health Products

Overview

The BIOCOOL LYO-F Series is a production-scale, pharmaceutical-grade freeze dryer engineered for the reliable, repeatable, and compliant lyophilization of heat-sensitive food ingredients, dietary supplements, probiotics, botanical extracts, and functional health products. Based on the fundamental principles of sublimation under controlled low-pressure and cryogenic conditions, the system removes water from frozen matrices via primary (sublimation) and secondary (desorption) drying stages—preserving biological activity, structural integrity, and chemical stability without thermal degradation. Designed to meet stringent requirements for GMP-aligned manufacturing environments, the LYO-F Series integrates robust mechanical architecture with process-critical control systems, enabling full traceability, reproducible cycle execution, and regulatory readiness for global markets.

Key Features

• Programmable Process Control System: Fully automated cycle management—from freezing and primary drying to secondary drying and automatic defrost—executed via preloaded or user-defined protocols.
• Dynamic Vacuum Regulation: Real-time pressure modulation during both sublimation and desorption phases optimizes mass transfer kinetics and reduces overall cycle time without compromising product quality.
• Industrial HMI Interface: 10.1-inch high-brightness touchscreen with intuitive navigation; operation requires no manual reference—supporting rapid operator onboarding and minimal training overhead.
• High-Frequency Data Acquisition: Temperature and vacuum sensors sampled at 50 ms intervals, ensuring precise temporal resolution for critical process monitoring and deviation detection.
• Comprehensive Recipe Management: Stores up to 2,000 validated or custom lyophilization protocols, each with versioned metadata, user attribution, and timestamped execution logs.
• Onboard Calibration Tools: Integrated procedures for temperature sensor (shelf and chamber) and vacuum transducer calibration, supporting long-term measurement integrity and audit compliance.
• Process Curve Visualization & Export: Real-time and historical plotting of shelf temperature, product temperature (via thermocouple input), chamber pressure, and condenser load—with CSV export for external analysis and regulatory submission.

Sample Compatibility & Compliance

The LYO-F Series accommodates diverse sample formats including bulk trays, stainless-steel pans, and stoppered vials (with optional loading/unloading modules). Its chamber geometry, shelf uniformity (±0.5 °C across full area), and condenser design support consistent drying of heterogeneous matrices—such as fruit purees, fermented cultures, enzyme blends, and herbal suspensions. Structural compliance includes adherence to GB 150.1–2011 (Chinese Pressure Vessel Code), PED 2014/68/EU, and ASME BPVC Section VIII Div. 1. Internal surfaces are electropolished to Ra ≤ 0.4 µm, meeting ISO 14644-1 Class 5 cleanroom compatibility when installed in controlled environments. All wetted components comply with FDA 21 CFR Part 11–ready data handling standards, and system architecture supports GLP/GMP audit trails per ICH Q5C and USP .

Software & Data Management

The embedded control software provides role-based access control (operator, supervisor, administrator), electronic signature capability, and immutable audit logging of all parameter changes, cycle starts/stops, and alarm events. Data files are stored in encrypted SQLite format with SHA-256 checksum verification. Export functions support PDF cycle reports, raw CSV datasets, and XML-based protocol interchange (compatible with MES/SCADA integration). Optional 21 CFR Part 11 compliance package includes digital certificate authentication, biometric or token-based sign-off, and configurable retention policies aligned with EU Annex 11 and FDA guidance.

Applications

• Stabilization of probiotic strains and live biotherapeutics without loss of viability
• Preservation of enzymatic activity in plant-derived nutraceuticals (e.g., bromelain, papain, superoxide dismutase)
• Production of instant-dissolving functional food powders (e.g., matcha, spirulina, collagen peptides)
• Lyophilization of pH-sensitive botanical extracts requiring low-temperature processing
• Scale-up from lab to pilot to commercial production using identical process parameters and thermal profiles
• Development of stable intermediate forms for encapsulation, tabletting, or sachet filling lines

FAQ

What is the maximum batch capacity supported by the LYO-F Series?
The LYO-F platform spans models from LYO-2F (40 kg/day) to LYO-400F (8,000 kg/day), with shelf area scaling from 0.2 m² to 400 m². Daily throughput is calculated based on standard aqueous feed concentration (10–15% solids) and typical drying kinetics for food/nutraceutical matrices.
Does the system support validation documentation (IQ/OQ/PQ)?
Yes—factory-issued IQ/OQ protocols are provided, and PQ templates aligned with ASTM F2699-21 and ISO 22053 are available upon request. On-site qualification support is offered globally.
Can the LYO-F integrate with existing plant SCADA or MES platforms?
Standard Modbus TCP and optional OPC UA interfaces enable bidirectional communication with industrial automation systems. Custom API endpoints are available for ERP-level integration.
What maintenance intervals are recommended for the refrigeration and vacuum systems?
Compressor oil and filter replacement every 4,000 operating hours; vacuum pump oil change every 1,000 hours; helium leak testing of welded joints annually or after major service events.
Is remote monitoring and troubleshooting supported?
Yes—secure TLS-encrypted remote access is enabled via optional VPN gateway, allowing real-time diagnostics, log review, and supervised parameter adjustment by certified field engineers.
