Freeze dryer is widely used in medicine, pharmaceutical, biological research, chemical and food and other fields. The Freeze Dryer articles are easy to store for a long period of time, and can be restored to the pre-freeze state before adding water and maintain the original biochemical characteristics. Huayu brothers vacuum freeze dryer for laboratory use or a small amount of production, to meet the requirements of most of the routine Freeze Dryer laboratory.
Freeze dryer connected to the power supply does not work how to do? Freeze dryer does not run the treatment method.
Cause: No voltage or voltage is too low
Countermeasure: Check incoming line power switch, fuse and remove the fault
Cause: The high voltage protection switch is disconnected
Policy: Reset Cause: Wiring loose
Action: Check wiring and tighten
Cause: The compressor motor burns out
Countermeasure: check, replace
Cause: AC contactor is damaged
Countermeasure: check, replace
Reason: Refrigerant leak in the refrigerated dryer
Countermeasures: leak, trap, add refrigerant
Cause: The automatic air switch is not open
Action: Turn on the automatic air switch
In the freeze dryer process, the growth of microorganisms and the role of enzymes can not be carried out, so to maintain the original equipment. Since the drying is carried out in a frozen state, the volume is almost constant, and the original structure is maintained, and the concentration does not occur. As the drying in vacuum, oxygen is very small, so some easy to oxidize the material has been protected. Freeze Dryer machine can eliminate more than 95-99% of the water, so that after drying products can be stored for a long time without deterioration. After drying the material loose porous, sponge-like, dissolved after the water quickly and completely, almost immediately restore the original traits. The freeze dryer is carried out at low temperatures and is therefore particularly suitable for many thermosensitive materials. Such as protein, microorganisms and the like will not degeneration or loss of biological vitality. So the freeze dryer is widely used in medicine. Drying at low temperatures, some of the volatile components of the material loss is very small, suitable for some chemical products, pharmaceuticals and food dry.
