Beijing Sihuan Freeze Drying Machine LGJ-H30 Standard Type

Beijing Sihuan Freeze Drying Machine LGJ-H30 Standard TypeMain features:

1. Structural design that complies with biopharmaceutical standards. The internal corners, surface roughness, shelf flatness, and internal materials of the freeze-drying chamber all meet pharmaceutical standards;

2. The control system is stable. Adopting PLC programmable logic control system and 10 inch color touch screen, the system runs more stably, with friendly human-computer interaction, Chinese English language conversion, and can achieve remote control on mobile and PC ends, with three-level permissions;

3. Real time display and recording of vacuum degree, cold trap temperature, sample temperature, shelf temperature, and forming freeze-drying curves. Data is stored once per minute and can continuously record sample and equipment condition data. It supports offline browsing, analysis, printing, and storage of data, and is equipped with USB communication interface and TCP interface;

4. The freeze-drying process can be controlled. The freeze-drying process is automatically controlled by programmable programs, and semi-automatic or fully automatic control can be switched in real time to achieve parameter control throughout the entire freeze-drying process;

5. The design of separating the freeze-drying chamber from the cold trap chamber not only meets the standards of pharmaceutical grade pilot testing machines, but also greatly improves the water capture efficiency and capacity;

6. Adopting shelf electric heating technology, temperature control for shelf placement, uniform and controllable temperature of the board layer, smooth board layer, and good conduction of cold and heat;

7. Dual machine cascade refrigeration technology. Adopting a fully enclosed compressor unit and environmentally friendly cold coal, the refrigeration is fast, the cold trap temperature is low, and the water capture ability is strong;

8. Equipped with compressor secondary start timing protection and pressure overload protection system;

9. The drying chamber adopts high pressure and low temperature resistant aviation acrylic material with high transparency doors, which can observe the entire process of sample freeze-drying changes;

10. The cold trap has an automated frost function;

11. Optional negative pressure aeration system interface. Built in 0.2 μ m filter element to reduce secondary contamination of samples, can be filled with nitrogen or inert gas;

12. Optional intermediate isolation butterfly valve: Conduct pressure rise testing and vacuum degree adjustment.
