this website has a good recipe

A must read:

Squish all the juice form the fruit.Then put them in the sun to dry them and sell dry fruit.

Use unbruised peeled thin sections of fruit (apples, for example). Cut them about as thick as a saltine, maybe a little thicker if you want. Dip apples in some lemon juice to keep them from turning brown. Spread out on clean oven racks, or hang from skewers in the oven. Use an oven temp of about 135F – prop the oven door open with a butter knife if needed – helps to vent some moisture and keep the heat from getting too high. Dry until still somewhat flexible. This should take 4 – 8 hours, depending on heat, humidity level, type of apple, and thickness of slices.

Other than that, look it up on the web.

Bananas also work well, but can be dried on a cookie sheet – turn halfway through (dry them until slightly crispy).

If you’re not to worried about dust and there are no flies around, you can also just thread them with needle and heavy thread, leaving an inch or so between each slice and just string the threads horizontally to naturally air-dry the apple slices.

Good luck, you’ll enjoy it.

Well, if you have a dehydrator (many places sell them), you just put slices of fruit in it, plug in the machine, and turn it on. In no time you’ll have dried fruit. My mom also used to puree fruit (like strawberries or peaches) to make my sister and I some healthy fruit “roll-ups” – technically called fruit leather.
