We have 2.
One is a 4 or 5 shelf Excalibur that is small, compact, and does a decent job on small scale drying jobs. It gets used a lot, as its petfect for small batch stuff, and herbs that we harvest regularly. Did rhubarb this spring, works fine, just takes a bit...not very noisy.
We do peppers in it, as well as herbs, fruits and tomatoes. Its small, so is easily set on a shelf in the garage, a full load of peppers takes a few days.Comes with fruit leather mats for the shelves, not my thing but have to admit, when it gets made I eat the hell out of it cuz its good.
The other one is a Weston, its about the size of a large wine fridge, a bit over 3' tall and has a bunch of racks...probably 16 or so.
Its very nice and can really produce in quantity.
It sits in the garage also, and since we picked it up used for about 100 bucks, was a no brainer deal, they are 500 plus new.
For large scale stuff this is great. We have filled it with sliced tomatoes and in a couple days they are ready for packing in oil, another day and the can be blitzed into powder and put in jars. (Tomato powder is a great ingredient to have on hand)
Apples, cherries(we do 50 plus lbs. every year) and pretty much anything you can fit on a shelf will be done given enough time. Clear door so you can see your stuff, which is nice. Lots of settings for temp and time, so no need to mess with it, set it and when it stops check it, can always add moe time, but is suprisingly accurate.
Humidity plays a role, winter dehydrating takes a bit longer of course.
A bit noisier that the Excalibur, but so much better for bulk that its worth it. Being in the garage the additional noise is no big deal.
Recommend both manufacturers here, never had an issue with either one.
