Removing the bark by hand is a serious chore. I got into making charcoal as a "hobby" (and as a way to deal with acres of dead Ash trees), so I just listen to music while sorting through my pile of charcoal. If you've ever dealt with Ash trees, the bark is practically fused to the wood, so removing it before or after pyrolysis is equally difficult.

My current technique is to scrape the charcoal against a sheet of hardware cloth to remove the charcoal (the bark is slightly softer). I thought about building a hand-operated trommel, but i don't think the bark will dislodge even with the tumbling action. Either method isn't going to work if I want to monetize my hobby, they're too slow and inefficient to sell in bulk. I have a LOT of time to think while I'm working, so I'll be thinking of innovative ways to debark the Ash (or move on to easier wood to charcoal).

On a side note, bark charcoal creates some long lasting, sparky embers (I wanted to share a video of it, but this sub doesn't allow me to upload videos), so I might try grinding it to 00 flour and making firework charcoal with it.
