Heating type vacuum freeze dryer

Pilot freeze dryers are widely used in the fields of medicine, pharmacy, biological research, chemical industry and food production. After the freeze-drying process, it is easier to store for a long time. After watering, they can return to their original state and maintain their chemical and biological properties.
NBJ-20F (silicone oil heating) freeze-drying process is completed in the same place (patented product). The cumbersome operation of the previous drying process is changed, the pollution of the material is prevented, and the automatic dry sublimation is realized. This model is equipped with shelf heating and has programmable functions. Freeze-drying curve can be memorized, with U disk extraction function, convenient for users to observe the material freeze-drying process.

Details

Main features

1. Freeze drying is done in the same place. The operation is simple and the drying effect is good.
2. The drying chamber door is made of acrylic material. Colorless and transparent, the whole process of freeze-drying can be observed.
3. The inflation (drain) valve adopts a safety diaphragm valve, which can be connected to an inert gas source. After drying, it can be filled with inert gas to extend the storage time of materials.
4. Patented air guiding technology, uniform ice trapping by cold trap, strong ice trapping ability.
5. Compressors of internationally renowned brands have high efficiency, long life and low noise.
6. Patented clapboard technology and clapboard temperature fuzzy control technology, the shelf temperature difference is small, the temperature control accuracy is high, and the drying effect is uniform.
7. Freeze-drying curve optimization control technology, which can control the cooling rate in the pre-freezing stage, and at the same time control the sample heating rate and the current vacuum degree in the sublimation and analysis drying stage.
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 formula contains 50 temperature control zones to improve the process optimization rate.
11. Intelligent data recording system, real-time record and display of cold trap temperature curve, sample temperature curve, vacuum curve, export data can be viewed and printed by a computer for various operations, which is convenient for process optimization and drying effect verification.
12. Flexible manual + automatic control, manual is used for the exploration process, and automatically used for mass production.
13. Real-time alarm display and historical alarm query function, convenient for fault diagnosis and equipment maintenance.
14. The vacuum degree is adjusted during the drying operation to avoid foaming and foaming of special materials and improve the drying efficiency.
15. User level and password can be set, decentralized operation management.

Application

This model is not only suitable for freeze drying of bulk (liquid, paste, solid) conventional materials, but also for drying of small bottles of materials. When the materials are ready for freeze drying, place them in the vial, and then start the freeze drying before the vial cap is opened. The capping device after freeze-drying presses the bottle cap tightly to prevent secondary pollution and re-absorb water for long-term storage.
