    Suitable Material Types for Different Freeze Dryer Types

    • Ordinary freeze dryer: Suitable for bulk materials.
    • Gland-type freeze dryer: Suitable for loading and lyophilizing materials in vials.

    Application: Vacuum freeze dryers are widely used in the fields of biological engineering, pharmaceutical industry, food industry, chemical industry, materials science and deep processing of agricultural and sideline products. The freeze-dried material is easy to be stored for a long time, and after adding water, it can return to the state before lyophilization and maintain the original biochemical characteristics.

    Usage Steps of Vacuum Freeze Dryer Machine

    • Ordinary Freeze Dryer
    1. Remove the pre-frozen material plate from cold trap and quickly load it into drying rack. Place the drying rack over cold trap and cover it with plexiglass cover. Lower end of glass cover should make full contact with O-ring.
    2. Tighten the vacuum valve and press the vacuum pump button. Then the vacuum pump will work and the vacuum will drop rapidly. It is normal for vacuum degree to drop below 15Pa, at which point lyophilization begins.
    3. After 24 hours, materials have completely dry. Open the vacuum valve for inflation. Press the vacuum pump button to stop it. Press the vacuum gauge button and vacuum display disappears.
    4. Remove the plexiglass cover and remove material tray from drying rack. At this point, drying work of the ordinary freeze dryer is completed.
    • Gland-type Freeze Dryer
    1. Place the pre-frozen vial (in the tray) into gland drying rack. Place the rack over cold trap and cover it with gland plexiglass cover. Lower end of glass cover should make full contact with O-ring.
    2. Tighten the vacuum valve and press the vacuum pump button. Then the vacuum pump will work and the vacuum will drop rapidly. It is normal for vacuum degree to drop below 15Pa, at which point lyophilization begins.
    3. After material is completely dry, turn the handle above plexiglass cover to rotate gland ball screw in the cover to move the original plate down. Press bottle cap into bottle, stop the cap in vacuum.
    4. Inflate, turn off the pump, and remove the plexiglass cover. Remove the material bottle for storage.
