  •   Monitor Vacuum System: Periodically check the vacuum pump and seals to ensure they are functioning properly and arrange for timely repairs if needed.
  •   Calibrate Sensors and Controllers: Regularly calibrate temperature, pressure, and humidity sensors to maintain accuracy and stability during the freeze-drying process.

How often do you need to defrost a freeze dryer?

The frequency of defrosting a freeze dryer depends on its usage and model. It’s generally recommended to defrost periodically based on production volumes and operational frequency. If frost buildup begins to affect the freeze-drying process or accumulates significantly, defrosting is necessary. This can be done by stopping the freeze-drying process and allowing the unit to thaw naturally or using a designated defrosting procedure.
