8 ㎡stainless steel 304 Freezing Dryer For Food Nutrition, Flower, Hospital
1. Before each start-up, first check the vacuum pump oil enough.
2. Unscrew the drain valve to let the remaining water flow out. Tighten the valve after draining.
3. Check the contact area between the freeze-dried chamber and the cold trap is intact, if necessary, clean and readjust.
4. Close all valves (valves connected directly to the lyophilizer, with the white knob turned upwards). Close the trap with the vacuum pump to be connected (behind the instrument, to the vacuum tube).
5. Open the cold trap power switch, turn on the vacuum pump power switch.
6. After 15 minutes, open the valve to which the trap is connected to the vacuum pump.
7. After 1 minute, the sample that has been pre-frozen (already in the freeze-dried bottle) can be hung on the bracket, and the corresponding valve can be opened to freeze-dry.
8. After lyophilization is complete, close the corresponding valve (white knob up) and remove the lyophilized bottle.
9. After all lyophilized bottles have been removed, turn off the vacuum pump and cold trap power.
10. After the frost in the cold trap has melted, open the drain valve to drain and close.
Precautions
1. The sample must be pre-frozen before lyophilization. The sample must be lyophilized in the solid state (frozen state). The longer the pre-freeze time, the better the lyophilization. The volume of the sample should not exceed 1/3 of the volume of the sample bottle.
2. In the freeze-dried if there is sample melting phenomenon, and the vacuum pump and cold trap work in good condition, the reason is not enough vacuum, where there is a leak. Check all valves are closed, freeze-dried cavity in contact with the surface of the cold trap is sealed, if necessary, clean the cold trap surface and freeze-dried cavity seal.
3. Regularly clean the cold trap cavity and freeze-dried cavity.
4. 15 minutes after the boot can be lyophilized, the purpose is to let the cold pre-cooling, let the vacuum pump preheat. This will enable the instrument to work in the best working condition.
5. After the end of the freeze-dried valve closed, freeze-dried bottle connected to the outside world, until the pressure balance can be removed after the bottle.
6. Regularly clean the dust inside the compressed bottle, the vacuum pump to refuel less oil.
