Features

– Dry chamber using aircraft grade acrylic materials, non-adhesive, high strength, and no leaks.
– Condenser pre-cooling function.
– Used DANFOSS compressor.
– Used Leybold brand vacuum pump in
– Brand hydraulic top-press system
– Oil-mist filter is standard configuration
– Can be charged nitrogen or inert gas to save after drying.
– Programmable, freezing, drying and defrosting will be program controlled.
– Automatic control system: Temperature heating control for each shelves, heating circulation monitoring protect, fuzzy PID control algorithm.
– Freezing-drying curve optimization control algorithm, temperature rise rate & vacuum value can be controlled during sublimation and analytical drying stage
– Defrost system: Non-electric heating defrost, more safety and fast.
– Lyophilized end test system: lyophilize end test will be start automatic when analytical drying finished, to ensure moisture content rate reaches standard
– Vacuum regular system: vacuum degree regular in sublimation and drying process to avoid special material foaming or blowing, accelerate lyophilized efficiency
– Pulse backfill system: slow, medium, fast three kinds of backfilling mode selection, avoiding the granular material and flocculent material being blown out effective loss problem inflatable produce.
– Automatic drainage system: interlock with vacuum system after draining to prevent any failure in vacuum system.
– Touch LCD display, easy to use.
– Can be work in automatic or manual operation, manual mode is used to explore the process parameters, automatic mode for process maturity.
– Data recording system: 1) data can be stored in machine in 3 months; 2) External U-disk storage (Optional); 3) PC-database storage (Optional)
– Monitoring system: real time system temperature and vacuum degree monitored, acquisition frequency 50ms / time.
– Lyophilization process recipe storage function: can store 500 set of fixed or user-defined lyophilized formulation process.
– PC remote monitor system: remote monitor working status of machine, max 1.5km distance (Optional)
– Eutectic point test function (Optional)
– Calibration function: temperature and vacuum calibration ensures long-term accuracy of the measured values.
– Freeze-drying curve searchable.
