Product Description
Large Capacity Vacuum Freeze Drying Equipment
Industrial freeze dryer for meat, seafood, and agricultural products with advanced vacuum freeze-drying technology.
Product Overview
This food-grade freeze dryer utilizes advanced vacuum freeze-drying technology to gently remove water from food materials at low temperatures. It effectively preserves the original nutrition, flavor, color, shape, and rehydration properties of fruits, vegetables, meat, seafood, herbs, and ready-to-eat snacks. Constructed with food-safe materials and a sanitary structure, it ensures stable and reliable performance for both small-batch trials and industrial food production.
Key Features
International Branded Core Components: German BITZER compressor, Japanese ULVAC vacuum pump, and components from world-renowned brands including Danish DANFOSS, American Omega, and Swiss REFCO for stable equipment operation.
High-End Process Design: Compliant with CGMP design specifications, with control system meeting FDA and EU standards featuring electronic signature and multiple password protection for pharmaceutical and high-end food industries.
Precision Temperature and Vacuum Control: Shelf heating temperature control at ±0.3°C (PID regulator), ultimate vacuum ≤13.3Pa, with adjustable range of 13.3-200Pa to match various material requirements.
Excellent Freeze-Drying Efficiency: Maximum condensate ice capacity of 2000KG per batch, total shelf area of 110.16㎡, rapid cooling from 30℃ to -40℃ in ≤30 minutes, and vacuum pressure reduction from 105 Pa to 133 Pa in ≤20 minutes.
Industrial Structural Design: Integral horizontal drum-type structure with suspended rail material conveying system, featuring 4 sets of SUS304 trolleys per drying/frozen library and tray capacity of 64 pieces for efficient large-batch processing.
