Yes! I own a Nesco Dehydrator similar to this one. It actually comes with a book that gives you the drying times and temps for different fruits.
Without knowing the specifics of what you want to dry, I'll be general. Cut or slice to the desired size (thicker will take longer. It takes a few tries to get the perfect size for you).
Then arrange on the trays with NO OVERLAP. Leave room between each piece. It's all about airflow!
Prep your fruit before drying by cutting, then as some suggest dipping in some lemon juice. I have not found the lemon juice step to be necessary, but some suggest it, so I'll include it here as an option. Then to get that extra sweet taste you need to add some white sugar to the sliced fruit. A simple sprinkle over top is fine. I like to put some more sugar on half way through when I flip the pieces (not required, but adds to it imo). You can also experiment by adding things to the sugar like cinnamon. A favourite of mine and friends/family is to use the pre-sliced pineapple in cans and sprinkle with cinnamon sugar.
Drying times will vary too much for me to tell you exact ones. It can be anywhere from 3 to 12 hours depending on thickness, fruit type, and desired dryness. The dryer it is the longer it will keep. If you like them a bit gummier, just keep in mind they can spoil faster. I'd suggest checking in on it every couple hours until you reach your desired dryness. Then keep a little notebook with your own drying times by experience.
Apples are probably the easiest place to start as they are cheap, forgiving, and easy to work with. The pineapple is pretty easy too.
Good luck and feel free to ask me anything else about dehydrating. It's become a fun hobby for not just dried fruit, but jerky, dried veggies, and drying/preserving my own herbs.
I use this one - https://www.amazon.com/NESCO-FD-60-Snackmaster-Express-Dehydrator/dp/B000LNVUJQ
The trays are easy to cut, leaving the outer ring for height. It works perfectly to dry filament.
I lucked up and found this at a yard sale for $5 years ago. I hated cutting the trays when I needed it for filament last year, but as luck would have it, I found another identical unit at a thrift store for $6.
Even still... currently $57 on Amazon.,.. it's a deal for what it does!
I mentioned this yesterday in a separate thread. Might be worth considering if you haven't purchased a dehydrator yet:
"If you're struggling with cold temperatures in your home and happen to have a dehydrator like this one https://smile.amazon.com/dp/B000LNVUJQ/ref=cm_sw_r_cp_apa_i_NGTJFbFVTFQTB?_encoding=UTF8&psc=1 that has a lid that contains the fan and a heating element, the top portion can double as a heat source and temperature controller. You can build an incubation chamber inside of a 66qt or larger tub and easily dial in temps."
I brought this one. I was actually able to get it for just a couple bucks more than the presco locally. Works great and I've done bananas and strawberries as well in it. Having the adjustable temperature control is nice to have.
I didn't realize it was that expensive.... probably better off getting it on black friday sale at walmart or something... I've had mine for at least a decade... im positive I didnt pay full price.....
I've got a Nesco fd60 that I've been using for a few years with frequent use with no problems. I use it mostly for drying my peppers for powders/flakes, but it works great for jerky as well.
I would really recommend you investing in a food dehydrator. I have this one and it is a great dehydrator to start out with.
You can make a ton of jerky for super cheap compared to the store-bought stuff and it tastes 100x better. Use eye of round roast for the meat and if you were to marinate it in dales, I would at the very least get the low sodium dales and even dilute it a little bit (maybe water + pineapple juice).
If you do this often just get a food dehydrator. Mine works amazing and while it seems expensive, running your oven like that is pretty pricey too I bet.
I make my own dehydrated boil in bag meals. I use THIS SITE as a template and just modify things as needed. I use a lot of powdered heavy cream, powdered eggs, powdered coconut milk, powdered cheese (all purchasable off amazon), instead of rice I dehdyrate cauliflower rice in my dehydrator.
It requires a bit of experimentation on your part since they don't translate 100% but I've made some good meals, bag tacos, butter chicken, fajitas, pizza casserole, buffalo chicken casserole, breakfast scrambles, cheeseburger casserole, etc. I've been playing around with the idea of trying to make a few keto cobblers.
Portion them out into quart freezer bags with smaller bags for spices/seasonings, when time comes to eat boil a bit of water, dump it in the bag and seal it up, let it sit for 10 minutes or so wrapped in a handkerchief or something then enjoy.
If you are dehydrating yourself you want to use LOW FAT meats. I know that's counter-intuitive for keto but high fat content foods won't dehydrate right, so use lean cuts, then add fat later (heavy cream powder, etc)
here's the DEHYDRATOR I use
Here is the HEAVY CREAM POWDER
I've priced everything out and for a day's worth of meals I'm around 10 bucks or so, vs Mountain House which are 5-8 bucks a meal and the Next Mile meals keto offerings which can be 15 bucks PER meal
I got a Nesco as an entry level dehydrator and have stuck with it because it works for the amount of dehydrating I do. Nesco Snackmaster Express dehydrator, 13.5 inches X 9.75 inches, White https://www.amazon.com/dp/B000LNVUJQ/

Punch the center out of a couple of your trays, and you can pre-heat or recondition your PLA spools before loading them up.
Extra Trays x2
Cut the trays out with a pair of scissors and tape them together and you have a Revivor oven for about $80... just don't run it over 140 degrees. I used a Meat thermometer to get the temperature right and works great
