As noted in the air fryer thread, the Breville Smart Oven Air has a dehydrator function, if you wanted something that's multipurpose for all sorts of cooking jobs. I don't use the dehydrator for fruit or jerky (although you certainly can), but I do make dog treats out of leftover pulp from juicing. Not the quietest thing (though I don't know how much noise a "regular" dehydrator makes) but it does the job. And you can put in at least three, if not four, racks, so decent ability to handle volume.
Disclosure: As previously noted elsewhere, I'm a P/T independent rep for Breville who does demos and training. I don't make commissions on sales. But I do own one and use it regularly for all sorts of stuff.
