I have a concept of a plan for desiccant spool weights (lemy.lol)

Which is to say, not very far on this at all but I think I have a good idea on how have my cake and eat it too for desiccant for my spools.

I am finding I can't get the humidity below about 50% in my AMS and the silica I am using needs constant refreshing.

Well it seems there is stuff called activated alumina that is pretty good and honestly about the same costs as silica beads, but I need to be able to put it in the oven to refresh it. Which doesn't work well with my 3d printed desiccant holders.

Insert, cheap tea strainers.
It seems I can get ones that are 4cm in width by 6cm in height that are made out of stainless steel that I can actually put straight in the oven.

So, I am working on getting the parts and items but was wondering if anyone else has done this or have any suggestions before I start grabbing stuff?

I used to use those mesh strainers for hops when I was still brewing beer. I would use them for desiccant drying too, but I don’t think my oven maintains low temperatures well enough to not melt the beads.

I got a food dehydrator instead which I think would work with your 3D printed desiccant holders if you make them out of the right materials.

Yeah I have a spool dehydrator but it doesn't battle the constant humidity and trying to swap the 2 that it can hold to the 4 in the ams is a pain if I am trying to dry desiccant too.

The whole point is the alumina isn't gonna melt or have any issues with the lower heat than it fully wants to dehydrate again. It technically should be refreshed in a kiln.

I’m not sure, but you should be careful while handling this stuff. It seems like it’s hazardous - the dust it produces in particular. You’re not supposed to handle it without gloves. I also can’t find any info about drying it out safely if the dust it produces isn’t supposed to be breathed in.

Maybe you’ve done this research already, and I’m overthinking this, but whatever you wind up doing, just be safe.
