I took plastic mesh screen and cut it into circles that fit inside the trays. I use them to dry blueberries (drain first), cranberries (cut in half first), pumpkin cubes, pears, and cherries (pit first). It makes the cleanup easier and all I have to do is lift out the screen and flex it to release the fruit. After 5 minutes or so, I seal it in airtight bags or jars. I generally add some brown sugar to my jerky marinade. Trim the fat from your meat well. Fat makes for nasty jerky. Oh yes, always put a paper towel underneath to catch any drips.

I would not recommend that you use a dehydrator to keep your powder dry.

I cut circles from parchment paper (the commercial stuff, not the stuff on rolls) and use that for goopy stuff like the refried beans, applesauce, etc...

The screens work great for stuff like celery that starts out fine but drop between the slats when they start to get dry.

Adapt and overcome. I like the way you think. ;)
