Four ring silicone oil freeze dryer

Four ring silicone oil freeze dryerLGJ-500B

Technical characteristics of the four ring silicone oil freeze dryer:

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, data storage capacity for 3 years (optional), equipped with data mobile storage USB serial port;

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 (optional), emergency stop switch (optional)；

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. The component materials and surface treatment comply with or exceed relevant national and industry regulations;

7. The freeze-drying automatic control system adopts PID control for both heating and cooling during the freeze-drying process, which can automatically achieve multi rate 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. Adopting imported compressor refrigeration technology, international standard green and environmentally friendly refrigerant, fast refrigeration, low cold trap temperature, and strong water capture ability;

10. Preparation before equipment freeze-drying and closing the valve body of the pipeline between the freeze-drying chamber and the water capture chamber 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 (optional), improving the efficiency of equipment freeze-drying;

11. Equipped with automated frost function;

Optional features:

1. Optional 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;

2. Optional automatic drainage and pipeline moisture detection;

3. Double pressure aeration system: reduces secondary contamination of the sample, can be backfilled with nitrogen or inert gas;

4. Plug pressing method: electric;

5. Provide clean room installation solutions;

6. Optional vacuum degree adjustment function, automatic and precise control of vacuum degree throughout the process (5Pa~80Pa, ± 1Pa);

7. Optional online eutectic point testing function to better optimize sample sublimation process;

8. Optional upper computer control;

9. Optional in place cleaning and in place sterilization functions;

10. Optional freeze-drying endpoint test.

11. Optional imported vacuum pump and high-speed vacuum pump oil
