Small-batch freeze dryers are designed for pilot-scale process development, process validation, and low-volume production between laboratory freeze-drying systems and larger commercial production equipment. The FD-10S, FD-30S, and FD-50S models provide different condenser capacities and shelf areas for applications including pharmaceutical development, botanical extracts, material research, and specialty food processing.
The product range covers 10 kg, 30 kg, and 50 kg ice condenser capacities per 24 hours, with shelf areas from 0.12 to 1.50 m2 and shelf temperature ranges extending from approximately -50°C to +80°C, depending on model.
