Place trays in the dehydrator at 55°C / 135°F for 6 to 8 hours. After 4 hours, check every hour or so. The dehydration time will depends on each fruit but also on how dry you want them to be. Fruits should be bendable and a bit chewy. Different fruits might not dehydrate at the same time. Some trays might need removing before others.
