Yes, an air fryer can dry foods when it holds low heat with steady airflow and enough rack space for long, even dehydration.
Air fryers move hot air fast, which is the same basic principle that a dehydrator uses. The difference is control. Drying fruit, herbs, or jerky asks for gentle heat, active circulation, and time. Many countertop units now include a “dehydrate” setting that drops to roughly 95–175°F and runs for hours. With the right setup—thin slices, single layers, and vented baskets—you can turn that compact cooker into a capable drying tool for small batches.
How Air Fryer Drying Works
Two forces do the work: warm air removes surface moisture while the fan sweeps that vapor away from the food. To prevent cooking, the temperature stays low and steady. When the heat is too high, sugars brown and proteins toughen before the center dries. When the heat is too low, water lingers and spoilage can follow. Hitting the middle range and keeping slices thin solves both issues.
Best Temperature And Time Ranges For Common Foods
The ranges below match what dedicated dehydrators use. Exact times depend on slice thickness, humidity, and the model’s fan strength. Start at the low end; extend the time until pieces snap, crack, or bend leather-like with no wet spots.
| Food | Prep Notes | Typical Temp & Time |
|---|---|---|
| Apples, Pears | Slice 1/8–1/4 in; dip in lemon water to slow browning | 130–140°F; 4–8 hrs |
| Bananas | Slice 1/4 in; brush with lemon or pineapple juice | 130–135°F; 6–10 hrs |
| Strawberries | Slice 1/4 in | 130–135°F; 4–8 hrs |
| Tomatoes | Core; slice 1/4 in or halve cherry types | 135–145°F; 6–12 hrs |
| Herbs | Rinse; pat dry; keep stems on | 95–110°F; 2–6 hrs |
| Peppers | Seed; slice into rings | 125–135°F; 6–10 hrs |
| Mushrooms | Brush clean; slice 1/4 in | 125–135°F; 4–8 hrs |
| Beef Jerky* | Trim fat; preheat strips to safe temps before drying | Dry at 130–140°F after precook |
*Food safety note for meat: Heat beef to 160°F and poultry to 165°F before drying, then keep the dehydrating range around 130–140°F until finished. That sequence speeds moisture loss and reduces risk. Your air fryer’s dehydrate mode can handle the second stage; use an oven or skillet for the preheat step.
Using An Air Fryer For Dehydrating: What Works
1) Check The Low-End Temperature
Many basket and oven models drop to 95–105°F on a dehydrate program, with adjustable steps up to 165–175°F. That low end keeps herbs green and delicate fruit from cooking. If your unit bottoms out at 170°F with no lower option, you can still dry sturdier produce like apples or tomatoes. Keep slices thinner and watch closely for early browning.
2) Load In Single Layers
Air needs space. Spread pieces in one layer on mesh racks or perforated trays. Overlapping traps steam and drags out the session. If you have stackable racks, rotate them halfway to even out edge-to-center drying.
3) Slice Thin And Even
Uniform thickness gives you uniform finish. A mandoline set to 1/8–1/4 inch keeps fruit chips crisp and reduces babysitting. For jerky, slice across the grain for a cleaner bite or with the grain for a chewier strip.
4) Keep Air Moving
Crack the basket or prop the door slightly during the last hour if steam builds up. Some oven-style units vent better than compact baskets. If your food still feels tacky after the target time, extend the session in 30-minute blocks until it reaches the right dryness test.
5) Test For Doneness
Fruit should be pliable or crisp with no squeeze of moisture. Herbs crumble between fingers. Jerky bends and cracks but does not break. When in doubt, cool a sample for five minutes, then check again; warm pieces feel softer than they will at room temp.
Step-By-Step: Apple Chips In A Basket Unit
- Wash two firm apples. Core if you like a clean ring.
- Slice at 1/8–1/4 inch. Dip in diluted lemon juice to keep color.
- Blot with paper towels to remove surface water.
- Arrange in a single layer on a mesh insert or rack. No overlap.
- Set the program to dehydrate at 135°F for 6 hours.
- Rotate racks at the halfway mark. Swap positions if you stack.
- Start checking at hour 5. Chips are done when crisp and dry.
- Cool on the rack. Store when fully cool to avoid trapped steam.
Safety Basics You Should Not Skip
Low Heat, But Not Too Low
Drying sits in the warm zone—hot enough to drive off water, not so hot that food cooks. For general produce, a range near 130–140°F works well, with herbs at the bottom end. Meat needs a separate preheat step to food-safe temperatures before going into the drying range.
Thin Slices And Lean Cuts
Fat goes rancid faster and blocks water loss. Trim visible fat from meat. Keep fruit and veg in even slices so the center finishes before edges darken.
Condition And Store
After drying, cool the batch, then “condition” fruit by placing pieces in a loosely filled jar for a week. Shake daily to spot beads of moisture. If you see any, return the jar’s contents to the air fryer on low heat to finish. For storage, use airtight containers in a cool, dark cupboard.
What Your Appliance Can And Can’t Do
Most modern units with a dehydrate program hold 95–175°F and can run 8–72 hours, which covers herbs, fruit, veg, and post-heated meats. Basket capacity is the limiter. Two to four racks hold only a few sliced apples or a single bunch of parsley. Larger oven-style models fit more but take more counter space. For big garden hauls, a dedicated dehydrator still wins on volume and rack count. For small weekly batches, the air fryer you already own is practical and quick to set up.
Fan Strength And Airflow
Dehydration depends on moving air. If your model’s fan is gentle, expect longer times. If it runs strong, watch for edge drying before centers finish and rotate trays as needed. Many units vary fan speed by program, so the dehydrate mode may feel quieter than air fry.
Racks, Mesh, And Spacing
Use fine-mesh inserts or silicone dehydrator mats to keep small pieces from falling through. Lift herbs off solid trays so air reaches both sides. Leave gaps between slices and around the rim of each rack for better flow.
Troubleshooting Common Snags
Edges Brown Before Centers Dry
Lower the temperature by 5–10°F and cut thinner slices. Rotate racks more often. Swap to mesh if solid trays trap steam.
Sticky Fruit After Hours
Humidity slows the finish. Extend time in short blocks and crack the door slightly near the end. Make sure pieces are not touching. For chewy fruit leather, line a tray with a non-stick sheet and dry until the sheet peels clean.
Uneven Batches
Mixed sizes dry at different rates. Group like-sized slices together. Pull dry pieces early and leave thicker ones to finish. Keep loads to one layer per rack.
When A Dedicated Dehydrator Makes Sense
If you dry several pounds at a time, need many racks, or want a low fan setting for herbs, a purpose-built dehydrator fits better. It runs cool, vents moisture well, and offers wide, even trays. That said, for a pint of berries or a bunch of kale chips, the air fryer is fast to set up, easy to clean, and already on your counter.

Sample Time Plans You Can Trust
Start with these practical plans for a first run. Adjust by humidity and slice thickness:
Herbs
Set 100–110°F for 2–4 hours. Strip leaves after drying and store in glass. Keep away from light to preserve aroma.
Citrus Zest
Use a peeler for wide strips with no pith. Dry at 100–120°F for 1–2 hours until brittle, then grind for baking blends.
Tomato Halves
Dry at 135–145°F for 6–12 hours until leathery. Pack in oil with garlic only if you plan fridge storage; oil changes shelf life.
Beef Strips*
Bring strips to 160°F first, then dry at 130–140°F until a test piece bends and cracks. Cool and store in airtight bags.
Sourcing Clear Guidance
If you want deeper charts on produce drying temperatures and storage, trusted preservation guides list the same low ranges used here. See the NCHFP drying guidelines. Meat safety guidance also stresses a preheat step before drying; the USDA jerky directions lay out the temperatures and tests. Use those references when planning batches that will sit on the shelf for weeks.
Bottom Line For Home Cooks
An air fryer with a true low setting, stackable racks, and a long timer can handle small-batch dehydration with solid results. Keep the heat gentle, slice thin, give air some space, and plan for time. Follow the meat preheat step when making jerky. For weekend snacks and herb jars, you’ll be pleased with the convenience; for bushels from the garden, a dehydrator still wins on volume.
