Cantaloupe is AWESOME! Here's what I do:
Cut it in half, stem to blossom, and scoop out the guts/seeds. Save that for the chickens, of course.
Lay the cut side down, and slice into 1" thick slices. Lay the slices on their side and trim off the rind. (I cut them that thick so that they don't fall apart when I pick them up after I cut off the rind.)
Cut into 3/8" thick slices and put on the dehydrator trays.
125-135 degrees, and roughly 12-16 hours to dry.
If you think of it, turn the pieces over about half way through.
Mine don't get to the crisp stage, they're more chewy. I store them in jars. When they're first done, I put them in a cupboard (out of direct light) for a couple weeks and monitor for any signs of mold. Then they go down to a tote in the basement.
