Overview
LICHEN LC-30F silicone oil heat conduction freeze dryer is a device that uses vacuum freeze drying technology for material drying. This technology maintains the original physical, chemical and biological properties of the material by rapidly freezing the dried substance at low temperature and directly sublimating and escaping the frozen water molecules in a vacuum environment. The dried material is in the shape of a porous sponge, with basically unchanged volume, which is easy to rehydrate and restore to its original state.
Features
1. Adopt 7-inch color LCD Touchscreen, PID control, can display temperature, Vacuum Level and browse Linear dispersion, intuitive operation.
2. The freeze-drying chamber adopts transparent organic Glass door panel, which is convenient for observing the whole drying process.
3. The drying chamber and the cold trap are split structures, with strong water capture capacity and short drying time.
4. Equipped with anti-return oil vacuum pump, using international standard KF quick connector connection, reliable and convenient.
The use of imported European Compressor and mixed environmental protection refrigerant, rapid cooling, low freezing temperature (cold trap temperature < -75 ℃).
6. The cold trap has a pre-freezing function, which can replace the low temperature refrigerator.
7. Built-in high-efficiency heat exchanger, effectively reducing the cold trap temperature and enhancing water capture capacity (7Kg/24H).
8. In-situ freeze-drying (pre-freezing and drying are integrated) can be achieved, and the material can be directly pre-frozen and sublimated on the Shelf.
9. The silicone oil heat conduction method is adopted, and the top layer is equipped with a silicone oil Hot Plate to make the drying indoor temperature more uniform.
10. Equipped with manual and automatic Operating Modes, it is convenient to explore the lyophilized Linear dispersion of new materials through manual mode.
11. With vacuum automatic control heating output function to avoid material collapse caused by excessive heating.
12. Equipped with a nitrogen gas charging valve, which can be filled with nitrogen or inert gas to maintain the state of the material after drying.
13. 20 programs can be stored, each program can be set to 36 segments, parameters can be modified during operation and drying Linear dispersion can be recorded.
14. With hydraulic capping function (model with T), it is convenient to cap the bottle after drying.
Principle
Vacuum freeze drying is based on the principle of sublimation. First, the dried substance is quickly frozen at a low temperature, so that the water in it solidifies into ice. Then in a vacuum environment, appropriate heat is provided to make the ice sublimate directly into water vapor without passing through the liquid state, and the water vapor is captured by the cold trap. The whole process The material is always in a low temperature state, and the ice crystals are evenly distributed, avoiding the side effects of condensation, foam, oxidation and other side effects caused by dehydration, so as to maximize the original properties of the material.
