I would like to know what is the best temperature for this dryer? Inside the collector I used a 0.5 mm thick metal sheet, and reflective film, and the glass is made of transparent sunlight sheet (endurance sheet)
I don't know the ideal temperatures, and differences in temperatures that make the dehydrator flush air. That would be a really cool ratio to find out!
My initial trouble shooting notes/ideas after seeing your pictures:
1) Glass: No sun treatment.
2) Collector: Back drop material needs to catch and maintain heat.
3) Cabinet: Seal door and remove air obstruction (currently a damper) at bottom of rear wall.
