Arrange on Trays: Place the banana slices on the trays of your freeze dryer in a single layer, ensuring pieces aren't overlapping.
Load into Freeze Dryer: Following the instructions for your specific freeze dryer model, load the trays containing the banana slices into the machine.
Freeze Drying Cycle: Start the freeze drying process according to the machine's settings. This typically involves a freezing phase followed by a drying phase that can take several hours.
After Freeze Drying:
Check for Dryness: Once the drying cycle is complete, consult your freeze dryer's manual to determine how to verify if the bananas are thoroughly dry and crisp.
Storage: Transfer the freeze-dried bananas to an airtight container or Mylar bag with an oxygen absorber for long-term storage at room temperature.
