As for how to dehydrate fruit once you have your machine, just follow this easy step-by-step guide:
1. Wash and dry fruit
Or don't. It's entirely up to you.

VIEW STORY2. Peel the fruit (if the peel isn't edible)
Rule of thumb: if you would eat the peel of the fruit in its natural state (apples, pears, etc.), you can eat it dried. Thin-skinned dried citrus peels can also be nice if you're into their slight bitterness, so feel free to leave lemons, limes, and oranges unpeeled, too.
3. Slice fruit in 1/4" to 1/2" pieces
There are a few caveats here. Smaller fruits can be left whole or halved as desired. For example, strawberries can be halved or sliced into rings as shown in the photo above. Apricots can simply be halved and pitted. Same with cherries—unless you also have a cherry pitter and want to simply pit the cherries and leave them whole. Blueberries and cranberries can be left whole, but you'll need to pierce their skin with a clean skewer or paring knife so the skins don't dry out and harden before the insides are fully dehydrated.

The smaller or thinner each piece is cut, the quicker it will dehydrate, so be sure to cut each fruit variety into pieces of the same size. Feel free to vary the size from one fruit variety to another, though—you can always remove the tray of dried apples from the dehydrator if they're done before the tray of dried mango.
4. Spray fruit with lemon juice
There are only a few times we'll suggest using bottled lemon juice over fresh. This is one of them. Its primary purpose here is to keep the fruit from browning, so it's a step you can skip entirely if you don't mind the murky visual. The easiest way to disperse the lemon juice evenly is to keep it in a food-safe spray bottle and spritz apple slices, banana chunks, etc. as desired.
5. Spread fruit slices in one layer on dehydrator racks
While the fruits' edges can be touching, make sure they do not overlap, which could cause the pieces to stick together and the overlapping parts to be less dehydrated than the rest of the fruit. Keep different fruits on different trays as each type will become fully dehydrated in a different amount of time. Place fruits more likely to drip on the bottom rack so that they don't drip onto other fruits below.
6. Follow your dehydrator manufacturer's recommendations for time and temperature.
No manual? Set the temperature between 125°F and 140°F. Dehydrating at 125°F will result in a more evenly dehydrated end product, while setting the temp to 140°F will make everything go a bit faster.
