Experimental Freeze Drying Machine LGJ-12H

Sihuan Furuike Technology Development (Beijing) Co., Ltd

LGJ-12H freeze dryer

Technical features:

1Color touch screen control system, with programmable automatic control for freeze-drying process（Optional), can be switched to manual operation in real time, realizing full process parameter control of freeze-drying process. During operation, the system automatically monitors, detects, records and stores relevant data, can store multiple fixed or custom programs, and can be monitored and maintained through remote system (optional 7-inch control screen), supporting big data and smart laboratory construction;

2. Continuous recording of real-time data, plottingFreeze drying curve preparation, data storage once per minute (adjustable storage interval), standard recording of 100000 times, data storage capacity for 3 years (optional), with data mobile storage USB serial port;

3productThe production has passed the ISO quality management system, obtained the EU CE certification, and the control system human-machine interface equipment 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 active protection is provided. Light alarms (optional) are also available;

5. It has the functions of automatic operation of freeze-drying, equipment vacuum pressure loss, equipment alarm, and automatic operation to protect materials. When the temperature of the cold trap is above -50 ℃, the vacuum pump cannot be turned on to prevent water vapor from entering and affecting the normal operation of the vacuum pump. It also has a vacuum pump maintenance prompt function and is equipped with a standard oil mist filter;

6. The cold trap chamber and material tray are made of sanitary grade stainless steel material. There are no coils inside the cold trap, which is smooth, corrosion-resistant, and easy to clean. It has material pre freezing function;

7. The cold trap drying chamber is made of aviation grade organic glass material that is resistant to high pressure and low temperature, and is covered with an explosion-proof layer film (optional). The entire freeze-drying process of the material can be observed;

8. The material shelf has program gradient electric heating function (except for LGJ-10C, LGJ-12H optional), special aviation heating film, controlled by PLD, built-in overheating protection, safe and reliable;

9. Adopting high-performance imported compressor single machine hybrid refrigeration technology, international standard green and environmentally friendly refrigerant, rapid refrigeration, low cold trap temperature, and strong water capture ability;

10. Equipped with a dedicated inflation valve port, it can be filled with inert and dry filtered gases;

11. Equipped with automated frost function;

Optional features:

1. Optional automatic drainage and exhaust, pipeline moisture detection;

2. Optional UPS uninterruptible power supply, providing continuous power supply guarantee for the control system for 20 minutes after sudden power outage. Within 5 minutes, the main circuit will be powered on, automatically determining safety conditions and restoring equipment operation according to the current stage;

3. Optional automatic re pressure mixing system, which can quantitatively (optionally) backfill nitrogen or inert gas;

4. Optional vacuum degree adjustment function;

5. Optional capping device.

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, eutectic point tester, inert gas inflation port, imported vacuum pump, high-speed vacuum pump oil, vacuum pump reverse shut-off valve, stainless steel inspection trolley;
