Introduction:

LGJ-30F/50F/100F (silicone oil heating) freeze dryer, in situ freeze-drying (patented product). It changes the tedious operation of drying process in the past, prevents the pollution of materials, and realizes the automation of drying sublimation. The machine has shelf heating and programmable functions, can remember the freeze-drying curve, convenient for users to observe the freeze-drying process of materials.

Technical parameters of lgj-50f vacuum freeze dryer

1. The patented product of our company is square warehouse in-situ vacuum freeze-drying machine, pre freezing and drying are completed in situ, easy to operate and good drying effect.

2. The door of drying chamber is made of acrylic material, which is colorless, transparent and can observe the whole process of freeze-drying.

3. The safety diaphragm valve is used as the air charging (water discharging) valve, which can be connected with inert gas source, and then filled with inert gas after drying to extend the shelf life of materials.

4. Professional gas diversion technology, uniform ice capture in cold trap and strong ice catching capacity.

5. International famous brand compressor, double cascade refrigeration, high efficiency, energy saving, long service life and low noise.

6. Patented diaphragm technology and diaphragm temperature fuzzy control technology, small shelf temperature difference, high temperature control precision and even drying effect.

7. The freeze-drying curve optimization control technology can control the cooling rate in the pre freezing stage, and control the heating rate of the sample and the vacuum value of the current stage in the sublimation and analytical drying stages.

8. Powerful sensor calibration function ensures the accuracy of long-term use of measured values.

9.7 inch real color industrial embedded touch screen + sh-hpsc-ii modular controller, high control precision, stable and reliable performance.

10. The specially designed fd-pilot control system can save hundreds of process formulas, each containing 50 temperature control sections to improve the process optimization rate.

11. The intelligent data recording system can record and display the cold trap temperature curve, sample temperature curve and vacuum degree curve in real time. The exported data can be browsed, printed and operated by computer, which is convenient for process optimization and drying effect verification.

12. Flexible manual + automatic control mode, which is used to explore the process manually and to batch production automatically.

Convenient for alarm and maintenance.

14. The user level and password can be set, and the operation management can be decentralized.
