This food-grade freeze dryer adopts advanced vacuum freeze-drying technology to gently remove water from food materials at low temperatures. It effectively retains the original nutrition, flavor, color, shape and rehydration properties of fruits, vegetables, meat, seafood, herbs and ready-to-eat snacks. Made with food-safe materials and a sanitary structure, it ensures stable and reliable performance for both small-batch trials and industrial food production.

• International Branded Core Components: The core compressor adopts the German BITZER brand, the vacuum pump is a Japanese ULVAC product, and the valves, sensors and other components of the refrigeration and vacuum systems are selected from world-renowned brands such as Danish DANFOSS, American Omega and Swiss REFCO, ensuring the stable operation of the equipment.
• Process Design Compliant with High-end Standards: The whole equipment follows the CGMP design specification, and the control system complies with FDA and EU standards with electronic signature and multiple password protection, meeting the compliance production requirements of pharmaceutical, high-end food and other industries.
• High Precision of Temperature and Vacuum Control: The shelf heating temperature can be precisely controlled at ± 0.3 ℃ (PID regulator), the ultimate vacuum can reach ≤13.3Pa, and the vacuum adjustment range is 13.3-200Pa, which can accurately match the freeze-drying process requirements of different materials.
• Excellent Freeze-drying Efficiency and Processing Capacity: The maximum condensate ice capacity of the condenser per batch is 2000KG, the total usable area of shelves is 110.16㎡, the refrigeration system can cool from 30℃ to -40℃ in ≤30min under no-load condition, and the vacuum system can reduce pressure from 105 Pa to 133 Pa in ≤20min, greatly improving the efficiency of freeze-drying production.
• Structural Design Adapted to Industrial Production: Adopting an integral horizontal drum-type structure and equipped with a suspended rail material conveying system, the drying library and frozen library are each equipped with 4 sets of SUS304 trolleys, and the tray loading capacity is up to 64 pieces, realizing efficient material transfer and large-batch processing.
