1. Pre-freezing and drying are completed in situ, which is easy to operate.
2. The door of the drying chamber is made of ACRYLIC material, which is colorless and transparent, and the whole process of freeze-drying can be observed.
3. The air-filling (water-draining) valve adopts a safety diaphragm valve, which can be connected to an inert gas source. After drying, it is filled with an inert gas to prolong the shelf life of the material.
4. Specialized gas diversion technology, the cold trap captures ice evenly and has strong ice capture ability.
5. International famous brand compressor, double-machine cascade refrigeration, high efficiency and energy saving, long service life and low noise.
6. The partition temperature fuzzy control technology, the shelf temperature difference is small, the temperature control precision is high, and the drying effect is uniform.
7. The freeze-drying curve optimization control technology can control the cooling rate in the pre-freezing stage, and at the same time control the sample heating rate in the sublimation and desorption drying stages, and select a vacuum degree adjustment system.
8. Powerful sensor calibration function to ensure the accuracy of measured values for long-term use.
9. 7-inch true color industrial embedded touch screen + SH-HPSC-II modular controller, high control precision, stable and reliable performance.
10. The professionally designed FD-PILOT control system can save hundreds of sets of process recipes, each set of recipes contains 50 temperature control sections, improving the process optimization rate.
11. The intelligent data recording system records and displays the temperature curve of the cold trap, the temperature curve of the sample, and the vacuum degree curve in real time. The exported data can be browsed, printed and operated on the computer, which is convenient for process optimization and drying effect verification.
12. Flexible manual + automatic control mode, manual is used to explore the process, and automatic is used for mass production.
13. Real-time alarm display and historical alarm query function are convenient for fault diagnosis and equipment maintenance.
14. The user level and password can be set, and the operation management can be carried out in a decentralized manner.
