UP-SFD-2vacuum freeze dryingMachine parameter table
UP medium-sized freeze dryer simplifies the tedious operation of small freeze dryers, prevents material contamination, and accelerates the sublimation of material moisture. This series of models has shelf heating and programmable functions, and can view the freeze-drying curve, making it convenient for users to observe the freeze-drying process of materials.
main features：
In situ pre freeze drying;
Silicone oil heating, high temperature control accuracy, shelf temperature difference ≤ 1 ℃, uniform drying effect;
Adjustable shelf temperature and controllable production process;
Can store N programs, each with 24 segments. The freeze dryer can modify program parameters during operation and record vacuum drying curves and data online; Can record all operation traces;
Touch screen, PLC control, can set startup password, display drying curve;
Square pallets are not easily deformed, easy to operate, and easy to clean;
Configure an inflation valve that can be filled with dry inert gas;
The drying room adopts high transparency, colorless and transparent organic glass doors, which can clearly observe the process of material changes during operation;
