Industrial Vacuum Freeze Dryer (15㎡) – Technical Overview A 15㎡ industrial vacuum freeze dryer is a large-scale lyophilization system designed for processing bulk materials in industries such as food, pharmaceuticals, biotechnology, and chemicals. This equipment removes moisture from products through sublimation—converting ice directly into vapor under vacuum—while preserving their structure, nutrients, and biological activity. Key Features 1. Large Drying Area (15㎡) - Accommodates high-volume production, suitable for batch processing of solids, liquids, or slurries (e.g., fruits, vaccines, enzymes). - Multi-layer trays or shelves ensure uniform heat distribution and efficient drying. 2. Vacuum System - High-efficiency vacuum pumps achieve and maintain low pressure (typically below 100 Pa), enabling sublimation at low temperatures (e.g., -30°C to -50°C). - Oil-free pumps may be used for contamination-sensitive applications like pharmaceuticals. 3. Refrigeration System - Cascade refrigeration or liquid nitrogen-assisted cooling ensures precise temperature control, critical for heat-sensitive products. - Condenser temperatures as low as -80°C trap vaporized moisture, preventing back-migration into the product. 4. Control & Automation - PLC or touchscreen interface allows programmable drying curves (pre-freezing, primary drying, secondary drying). - Sensors monitor temperature, pressure, and moisture content in real time for consistent results. 5. Material Compatibility - Constructed with 316L stainless steel for corrosion resistance and compliance with GMP/FDA standards. - Sanitary design with CIP (Clean-in-Place) options for sterile environments. Applications - Food Industry: Preserves flavor, color, and nutrients in coffee, herbs, seafood, and instant meals. - Pharmaceuticals: Stabilizes vaccines, antibiotics, and probiotics with extended shelf life. - Biotech: Freeze-dries enzymes, cells, and diagnostic reagents without denaturation. Advantages - Quality Retention: Low-temperature processing avoids thermal degradation. - Efficiency: 15㎡ capacity balances throughput and energy use, with optional heat recovery systems. - Scalability: Modular designs allow integration with upstream/downstream production lines. Considerations - Energy Use: Optimized insulation and variable-speed compressors reduce operational costs. - Maintenance: Automated defrosting and self-diagnostic features minimize downtime. This industrial freeze dryer combines advanced lyophilization technology with robust engineering, making it ideal for high-value products requiring precise dehydration.
