Wheaton ATC Solar Dehydrator air exit question

What would happen if we skipped the false wall entirely and just let the air exhaust through a vent in the bottom once it has settled instead of forcing it back up to the top again? Sorry if this is a dumb question, but I watched the 1.5 hour dehydrator video and couldn't answer it for myself.

Thanks!

The top part of the glass and the added lift is adding draw to the system.  It will circulate air more poorly and possibly even stall without the second part of the chimney.  As it is designed it both blows going in and sucks going out.

I see. Thank you for explaining. Has anyone actually witnessed this done in real life and proved its failure, or is a hypothesis?

Dehydrator no.  But here is the experience I am basing my comment on.  In convective mode the heat piles up and circulations slows.
