Industrial Vacuum Freeze Dryer (10㎡) – Technical Description The 10㎡ industrial vacuum freeze dryer is a high-capacity, advanced dehydration system designed for large-scale processing of heat-sensitive materials, including food, pharmaceuticals, and biological products. Utilizing lyophilization (freeze-drying) technology, it preserves the structural integrity, nutritional value, and shelf life of products by removing moisture under low-temperature and vacuum conditions. Key Features 1. Large Drying Area (10㎡) - Accommodates bulk processing with uniform drying performance across multiple trays. - Ideal for industrial-scale production of freeze-dried fruits, vegetables, meats, dairy, enzymes, vaccines, and probiotics. 2. Precision Freeze-Drying Process - Pre-freezing Stage: Samples are frozen to temperatures as low as -50°C to -80°C, ensuring complete solidification. - Primary Drying (Sublimation): Under vacuum (≤10–30 Pa), ice sublimates directly from solid to vapor, retaining product structure. - Secondary Drying (Desorption): Removes residual moisture at slightly elevated temperatures (20°C–60°C) for optimal dryness (≤1–5% moisture content). 3. Advanced Control System - PLC + Touchscreen HMI: Enables programmable drying curves, real-time monitoring of temperature, vacuum levels, and condenser status. - Data Logging: Records process parameters for compliance with GMP, FDA, or HACCP standards. 4. Robust Construction - Stainless Steel (304/316L): Corrosion-resistant chambers, shelves, and condensers for hygienic operation. - Oil-Free Vacuum Pump: Reduces contamination risks and maintenance needs. - Cascade Refrigeration: High-efficiency cooling system ensures rapid condenser temperatures (≤-55°C). 5. Energy Efficiency & Safety - Heat Recovery Systems: Minimize energy consumption during prolonged cycles. - Fail-Safe Alarms: Over-temperature, vacuum leaks, and power failure protections. Applications - Food Industry: Coffee, herbs, seafood, ready-to-eat meals. - Pharmaceuticals: Antibiotics, vaccines, protein-based drugs. - Biotech: Microbial strains, diagnostic reagents. Advantages - Preservation: Retains 95%+ of original flavor, color, and bioactive compounds. - Extended Shelf Life: 2–25 years without refrigeration. - Customizable: Optional CIP/SIP systems, modular designs for scalability. This 10㎡ industrial freeze dryer combines reliability, automation, and compliance for demanding production environments.
