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 LFD-30F (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.
1. In-situ vacuum freeze dryer is our company's patented product, which can finish pre-freezing and drying in-situ, easy to operate, good drying effect.
2. The drying chamber door is made of ACRYLIC material, which is colorless, transparent and can be observed in the whole process of lyophilization.
3. The pneumatic (discharge) valve adopts a safety diaphragm valve, which can be connected to an inert gas source. After drying, it is filled with inert gas 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 temperature difference of the shelf 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 accuracy, 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 inquiry function, convenient for fault diagnosis and equipment maintenance.
14. User level and password can be set and decentralized for operation management.
