I kept burning my desiccant beads when drying them out in both the oven and microwave. So I found this cheap food dehydrator on Temu https://share.temu.com/IPTV5vyBSHA and made this tray to fit on each rack.
I'm using old desiccant in the pictures. You can see the mix of burnt beads with the good ones. But the pics clearly shows that this works well.
The lid has a small opening in the corner that acts as a spout to cleanly pour the beads back into whatever containers you're using.
Be sure to use PETG.
******Make sure that the settings are as follows: In strength, set the top and bottom layers to 0. Sparse infill density to 75% and pattern to triangle.******
