  Bench Top Lyophilizers are widely used in medical, pharmaceutical, biological research, chemical and food industries. The freeze-dried articles are easy to preserve for a long period of time. After adding water, they can return to their pre-lyophilized state and maintain their original biochemical characteristics. Huayu Brothers vacuum freeze-drying machine is suitable for laboratory use or small-scale production, and can meet the requirements of most labs for routine freeze-drying.
  What should I do if the power supply to the freeze dryer does not work? How does the freeze dryer not operate?
  Reason: There is no voltage or low voltage on the incoming line
  Countermeasures: Check the line power switch, fuse, and troubleshooting
  Reason: High voltage protection switch is disconnected
  Policy: Reset Cause: Loose wire
  Countermeasure: Check the wiring and tighten
  Cause: Compressor motor burned out
  Countermeasures: check, replace
  Cause: AC contactor is damaged
  Countermeasures: check, replace
  Reason: refrigerant leak in refrigeration dryer
  Countermeasures: Check leaks, leaks, and add refrigerants
  Reason: Automatic air switch is not turned on
  Countermeasure: Turn on the automatic air switch
  During the freeze-dryer process, the growth of microorganisms and the action of enzymes can not be carried out, so the original costume can be maintained. Since the drying is performed in a frozen state, the volume is almost constant, the original structure is maintained, and no condensation occurs. Since the drying is carried out under vacuum, there is very little oxygen, so some easily oxidized substances are protected. Freeze dryer drying can eliminate more than 95-99% of water, so that after drying products can be stored without deterioration. The dried material is loose and porous, and it is spongy. It dissolves quickly and completely after adding water, and it almost immediately restores its original properties. Bench Top Lyophilizers operate at low temperatures and are therefore particularly suitable for many heat-sensitive materials. If proteins, microorganisms and the like do not degenerate or lose their vitality. Therefore, Bench Top Lyophilizers are widely used in medicine. When it is dried at low temperature, some volatile components in the material lose very little, which is suitable for some chemical products, drugs and foods.
