Product Description

LGJ-50FY Stoppering Type Freeze Dryer ( also name of Top Press Type Silicon Oil Heating Freeze Dryer ), is 0.5m2 tray area, withj 3pcs tray shelves. LGJ-50FY Stoppering Type 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 maintain their chemical and biological characteristics after being watered.

Freezing and drying process of LGJ-50F silicon oil heating freeze dryer are finished in the same place. 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. LGJ-50F silicon oil heating freeze dryer can memorize freeze-dried curves for users to observe the lyophilization process of materials.


1. The company’s patented product square warehouse in-situ vacuum freeze dryer, pre-freezing, drying in-situ, easy to operate, good drying effect.

2. The drying chamber door is made of ACRYLIC material, which is colorless, transparent and observable for lyophilization.

3. Inflatable (discharge) valve adopts safety diaphragm valve, which can be connected to inert gas source, and is filled with inert gas after drying to extend the shelf life of the material.

4. Patented gas guiding technology, the ice trap is evenly trapped and the ice trapping ability is strong.

5. Internationally renowned brand compressors, dual-machine cascade refrigeration, high efficiency, energy saving, long service life and low noise.

6. The patented technology of the separator and the fuzzy control technology of the separator temperature, the shelf temperature difference is small, the temperature control precision is high, and the drying effect is uniform.

7. Freeze-drying curve optimization control technology, which can control the cooling rate during 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 to ensure accurate measurement of long-term use.

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

10. Professionally designed FD-PILOT control system can save hundreds of process recipes, each group contains 50 temperature control sections to improve process optimization rate.

11. Intelligent data recording system, real-time recording and display of cold trap temperature curve, sample temperature curve, vacuum degree curve, export data can be browsed and printed by computer and various operations to facilitate process optimization and drying effect verification.

12. Flexible manual + automatic control mode, manually used for groping process, automatically used for batch production.

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

14. Adjust the vacuum during the drying process to avoid foaming and blowing of special materials and improve drying efficiency.

15. User level and password can be set and decentralized for operation management.
