A low-temperature setting (typically 95-170F) on select air fryers that slowly removes moisture from food to create dried snacks like fruit chips, beef jerky, dried herbs, and yogurt drops. The dehydrator function lets families make preservative-free snacks at home with no added sugar or artificial ingredients.
A rotating spit or tumbling basket feature found primarily in oven-style air fryers that slowly turns food for even browning on all sides. The rotisserie function combines slow rotation with convection heating to cook whole chickens, roasts, and larger items with consistent results in one appliance.
