DGJ-100E Pilot Production Freeze Dryer (CAT#: STEM-AL-4580-ZJF)

DGJ-100E Pilot Production Freeze Dryer is designed for pilot and production freeze-drying with controlled shelves and separated chambers. The system freezes the loaded material and removes ice by sublimation under reduced pressure. The source identifies the system as a controlled vacuum freeze dryer. Detailed drying-area data are not provided in the source. Automatic vacuum monitoring is included in the documented control architecture. The cold-trap system is arranged to condense vapor released during primary and secondary drying. The source describes controlled shelves or trays for sample loading. Electronic control records operating parameters and supports process review through stored curves or exported data where specified. The system supports repeatable freeze-drying within the documented temperature, vacuum, load, and environmental limits.
