[Homeroast] Air circulation inside grill roaster?

I'm working on a grill-based roaster and plan on adding a fan-driven
circulation loop with a cool-air intake valve so I can rapidly adjust
temperature if needed. I'd like to keep it a closed loop as much as
possible to keep efficiency high and will probably use an Arduino as the
overall controller. Gas flow will be adjusted by hand and the stirring
fan/air inlet should control temperature profile as long as my initial gas
flow settings are sane.
