The freeze-vacuum drying chamber is a large-scale freeze-drying system designed specifically for industrial continuous production. Its core drying chamber features a modular cabin structure, capable of processing batches of 500kg to 5 tons. The main body of the drying chamber is constructed from double-layer SUS304 stainless steel and equipped with a professional-grade pneumatically sealed door system, achieving a high-sealing performance of 10^-2 Pa.m³/s, an industry-leading standard.
This equipment integrates a -65°C deep pre-freeze function and a wide temperature range of -55°C to +70°C. The vacuum system utilizes a three-stage Roots pumping unit, capable of pumping a 30m³ chamber to a working vacuum of 5Pa in 15 minutes. The innovative three-dimensional heating system, with 48 independently temperature-controlled shelves, achieves precise temperature uniformity of ±0.8°C. It is equipped with a large-capacity spiral cold trap at -82°C, a water capture capacity of 1200kg/24h, and an integrated automatic defrost function.
The intelligent control system utilizes an industrial-grade PLC+SCADA architecture, supports storage of 1,000 process recipes, and complies with the data traceability requirements of FDA 21 CFR Part 11. The specially configured CIP online cleaning system and VHP sterilization module meet pharmaceutical-grade GMP requirements. This equipment is widely used in large-scale production of biological products, high-end foods, specialty materials, and other fields. Compared with traditional models, it increases drying efficiency by 40% and reduces energy consumption by 25%, making it a core equipment for modern freeze-drying production.
