You could even have a sliding door that isolates the collection chamber and allows you to quench and cool the biochar before its removal.

Crap, I just realized, I'm describing an un-insulated batch box rocket with the door on the "wrong end", optimized for incomplete combustion by limiting oxygen with a progressive flame front...

It should be possible to incorporate an auger to automate loading. The tricky parts will include 1) synchronizing the feed rate to the rate of pyrolysis (it will depend on the type of material, moisture content, packing density, etc),
and 2) figuring out how to automate removal of the finished biochar.

That's my roommate. He's kinda weird, but he always pays his half of the rent. And he gave me this tiny ad:
