Have you tried propping a wooden spoon in the door to see if the overall temp drops to dehydrator range? I can usually get my oven down to about 140f that way.
I got 9 tray Excalibur dehydrater with time and temp on Craigslist for about $100. Barely used. It’s one of those kitchen appliances that is often gets resold because of the space it takes up and how little it’s actually used. We love it and use it all the time. If u have space, Definitely recommend getting the larger size.
Fruit roll ups for the tots, beef jerky, yogurt, proofing bread, making powders (beetroot, purple potato, basically any greens from garden), crackers… it’s not daily , but But when we do use it we do you hydrate a lot at a time. Don’t recommend doing it indoors, but one time I marinated scallops soy sauce and made my own dried scallops for xo sauce.
Thanks. One of our daughters used one some years ago when she and her husband were heading out on a six week backpacking and climbing trip in the central Sierra Nevada. So I tended to think of it in that context.
