LGJ-20/30/40G PLUSfreeze dryer

Technical features:

1. The control software system is LINUX system, and the freeze-drying process is automatically controlled by programmable programs, which can be switched to manual operation in real time to achieve full parameter control of the freeze-drying process. During operation, the system automatically monitors, detects, records and stores relevant data, and can store multiple fixed or user-defined programs. The stored programs are ≥ 100（Can be increased to 600 according to customer needs）Each program step is ≥ 36, achieving multi-level management, and can be monitored, tested, and maintained through the standard remote system. It supports the construction of big data and smart laboratories, as well as audit tracking;

2. Continuous recording of real-time data, drawing of freeze-drying curves, storing data once per minute (with adjustable storage interval), standard recording of 100000 times, equipped with USB serial port for mobile data storage;

3The product production has passed the ISO quality management system, obtained the EU CE certification, and the control system human-machine interface complies with NEMA (International Electrical Manufacturers Association) protection regulations;

4. The system is equipped with various sensors that record and display vacuum degree, cold trap temperature, material temperature, and shelf temperature in real time. Operation error alarms can be triggered in real-time when temperature and pressure abnormalities occur during operation, and the system actively protects the operation,Adjustable sound and light alarm, emergency stop switch；

5. It has the functions of automatic operation of freeze-drying, equipment vacuum pressure loss, equipment alarm and automatic operation to protect materials, and vacuum pump maintenance prompt function;

6. In situ freeze-drying, the internal corners, surface roughness, shelf flatness, and internal materials of the freeze-drying chamber meet pharmaceutical standards, are smooth, corrosion-resistant, and easy to clean;

7. The freeze-drying automatic control system adopts PID control for both heating and cooling during the freeze-drying process, which can automatically achieve repeated pre freezing, quick freezing, and slow freezing of materials;

8. The manufacturing process of special mechanical technology ensures that the surface of the shelf is flat and the internal circulation path has the same diameter, allowing the intermediate medium (low viscosity silicone oil, 25 ℃, 5cSt) to circulate evenly and steadily inside the shelf, with uniform temperature, good heat and cold conduction, and improved freeze-drying efficiency;

9. External cold traps improve the water capture capacity of equipment, reduce the interference of cold trap temperature on materials during freeze-drying process, ensure consistent freeze-drying quality of materials and stable experimental data, improve freeze-drying efficiency, and reduce energy consumption;

10. Adopting imported compressor dual machine cascade refrigeration technology, international standard green and environmentally friendly refrigerant, rapid refrigeration, low cold trap temperature, and strong water capture ability;

11. Equipping equipment with butterfly valves for pre drying preparation and closing the pipeline between the freeze-drying room and the water capture room after freeze-drying can ensure that materials are loaded and unloaded in a clean environment and products are pre frozen. After freeze-drying, it can be measured and controlled to determine whether the freeze-drying of materials has ended, improving the efficiency of equipment freeze-drying;

12. Equipped with automated frost function;

13Equipped with UPS uninterruptible power supply,After a sudden power outage, the control system will continue to provide power protection for 20 minutes. Within 5 minutes, the main circuit will be powered on, and the safety conditions will be automatically determined to restore the equipment to operate according to the current stage;

14. Equipped with imported vacuum pump.

15. Equipped with vacuum degree adjustment function, the vacuum degree is automatically and accurately controlled throughout the entire process (1Pa~80Pa, ± 1Pa);

16. Equipped with upper computer control;

17. Equipped with freeze-drying endpoint testing;

Optional features:

1. Optional automatic drainage and pipeline moisture detection;

2. Automatic re pressure aeration system: reduces secondary contamination of the sample, and can be quantitatively (optionally) backfilled with nitrogen or inert gas;

3. Optional plug pressing method: manual or electric;

4. Provide clean room installation solutions;

5. Optional eutectic point and melting point testing function to better optimize the sample sublimation process;

6. Optional multi manifold bottle hanging device, freeze-drying bottle (eggplant shaped bottle and wide mouth bottle), ampoule tube freeze-drying rack, ampoule tube sealer, penicillin bottle capping machine, imported vacuum pump, high-speed vacuum pump oil;
