Anyway who wants a powder that is the fine as flour. Not me
There is a lot of wisdom in both of Jamie's comments. Make sure they are dry. 8 hours at 55C is probably not enough. My cheap azz dehydrator had a 85C thermostat and it would take 8-12 hours. I've since changed the thermostat, but that is another thread topic.
Super fine powders are really tough on the nose when they get airborne. I'm okay with a little coarser grind on the really hot powders.
Any cheap $20 coffee grinder will work fine, or Jamie's blender idea. pepper skins are not tough to slice through.
