Heat pump dryers can be used to dry peaches. Here are some basic temperature and time setting suggestions:

Temperature setting: It is recommended to set the temperature between 50°C and 60°C to avoid peaches from overheating and losing their nutritional value and taste.

Time setting: The drying time depends on factors such as the size, humidity and quantity of peaches, and generally takes 8 to 12 hours to dry. It is recommended to check the dryness of the peaches several times during the drying process and adjust the time as needed.

Slicing: Peaches can be sliced into even slices for faster drying.

Pre-drying treatment: Before drying, a light layer of honey or syrup can be applied to the surface of peaches to enhance texture and flavor.

Overall, make sure your heat pump dryer is set to the proper temperature and time to avoid overcooking or drying out. Periodically check how dry the peaches are during the drying process and adjust the time as needed for optimal drying results.
