Product Description


LGJ-20FY Top Press Type Experimental Silicone Oil Heating Vacuum Freeze Dryer is widely used in medicine, pharmacy, biology research, chemical industry and food production ,etc. After the freeze drying process,a long term preservation is much easier. They can be restored to the original state and mantain their chemical and biological characteristics after being watered.

Freezing and drying process of LGJ-20FY (silicon oil heating)  are finished in the same place (patented product). It changes the cumbersome operation of the drying process in the past, prevents the contamination of materials, and realized dry sublimation automatically. The model is equipped with shelf heating and has programmable functions. It can memorize freeze-dried curves and comes with u-disc extraction function for users to observe the lyophilization process of materials.


This model is not only suitable for the freeze drying of bulk (liquid, pasty, solid) conventional materials, but also suitable for the drying of the vials materials. When the materials are ready for freeze-drying, they are put into in the vial, then begin freeze drying before the vial's lid unsealed. The capping device compacts the vials' lids after freeze drying to prevent secondary pollution, re-adsorb water, and facilitate long-term storage.

NADE LGJ-20FY Top Press Type Silicone Oil Heating Vacuum Lyophilizer/freeze drying equipment/freeze dryer for vial


1. It is our company's patented product . Freezing and drying is finished in the same place. It is easy to operate,and have a good drying effect.

2. The ACRYLIC material is used for the drying chamber door. It is colorless, transparent, and the whole process of lyophilization can be observed.

3. Inflatable (drainage) valves use safety diaphragm valves, which can be connected to an inert gas source,  and  filled with inert gas after drying to extend material storage time.

4. Patented gas diversion technology, uniform ice catching in cold traps, and strong ice catching capability.

5. Internationally renowned brand compressors, high efficiency, long life, low noise.

6. Separator patented technology and partition temperature fuzzy control technology, the shelf temperature difference is small, the temperature control accuracy is high, and the drying effect is even.

7. The freeze-drying curve optimization control technology can control the cooling rate in the pre-freeze phase, and at the same time, it can control the sample heating rate and the current stage vacuum degree in the sublimation and analytical drying stages.

8. The powerful sensor calibration function ensures the long term accuracy  of the measured value.

9. 7-inch true color industrial embedded touch screen + SH-HPSC-II modular controller, high control accuracy, stable and reliable performance.

10. The professionally designed FD-EMB control system can save hundreds of process recipes. Each recipe contains 50 temperature control zones to improve the process optimization rate.

11. Intelligent data recording system, real-time record and display the cold trap temperature curve, sample temperature curve, vacuum curve, export data can be viewed through the computer and print a variety of operations to facilitate process optimization and verification of drying effect.

12. Flexible manual + automatic control, manually used for groping the process, automatically used for mass production.

13. Real-time alarm display and historical alarm query function to facilitate fault diagnosis and equipment maintenance.

14. Vacuum adjustment during drying operation to avoid foaming and blowing of special materials and improve drying efficiency.

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