The split-type freeze-drying chamber separates the freeze-drying chamber (material chamber), vacuum condenser (water trap), and refrigeration, heating, and control systems into independent modules, which are connected through pipelines to work in coordination. Its core advantage lies in the compact structure of the freeze-drying chamber, high space utilization rate, and ease of cleaning and maintenance. The condenser can be placed independently, featuring a large capacity, high water capture efficiency, and avoiding contamination of the materials inside the warehouse. This system is particularly suitable for large-scale production, multi-variety material handling, and biopharmaceuticals with strict cleanliness requirements, and other fields.
