Sunlight heats the black mild steel surface of the drier, which in turn radiates heat and produces convection. Hot air rises through the wet product in the stainless steel trays, and warm humid air exists through the exhaust chimney. The trays can be easily accessed through a door in the side of the drying chamber.
