Vacuum freeze dryer

Product ID:LGJ-25C


1. Adopt PLC programmable logic control system, which is easy to operate, stable and reliable, and environmentally friendly;

2. The control screen is a color touch screen with friendly human-computer interface. The display screen has the function of lock screen;

3. Display and record vacuum degree, cold trap temperature, material temperature and shelf temperature in real time and form freeze-drying curve, data stored every minute, continuous recording of material and equipment status data, support data offline browsing, analysis, printing and storage, configuration USB Data storage serial port;

4. It adopts imported closed compressor, single machine mixed environmental protection refrigeration technology, international standard green environmental protection cold coal, rapid cooling, low cold trap temperature and strong water capture capacity;

5. The cold trap cavity, material tray, material rack and the top contact surface of the fuselage are all made of 304 stainless steel. There is no coil in the cold trap cavity, which is smooth, corrosion-resistant and easy to clean.

6. The cold trap has the independent pre-freezing function of the previous sample, no need to be equipped with ultra-low temperature refrigerator and liquid nitrogen treatment.

7. With the compressor secondary start delay protection and pressure overload protection system.

8. Adopt anti-return oil vacuum pump, the main machine and the vacuum pump are connected by the national standard KF25 quick release flange.

9. The drying chamber adopts high-pressure and low-temperature-resistant aerospace acrylic material with high transparent door to observe the whole process of material freeze-drying change.

10. With cold trap automatic frost function.
