Solar food dehydrator

If you recall the solar drier prototype from a few posts ago you'll recognize it here, though now paired with our new Helios array.
The Vesta was underpowered so we decided to hook it up with a 35 sq. ft Helios array. 
Fraser administers the 'smoke test' where we place a burning stick at the air intake and count out how long it takes for it to escape through the chimney, giving us a rough idea of airflow. We're running at about 45 cubic feet per minute at a max of 150F. This is OK performance but we've still got some tinkering around to optimize the system. 
This is a test batch of about 10lbs of nixtamalized corn, AKA hominy. Still 
a couple hours of drying time left to go but we're hoping to have a fully 
dried product in a single day of drying. 
By midweek we should be done building 'la piece de resistance', a waist height cooking console with multiple configurations for boiling, frying, baking and roasting!
