Abstract
Tray assemblies and methods of their use to dry products with sunlight. Such a tray assembly includes at least a first base having four side walls, a bottom wall, legs configured to support the bottom wall above the surface when resting thereon, side wall holes in the side walls, and bottom wall holes in the bottom wall. A cover is releasably coupled to the base to define an enclosure between the cover, the side walls, and the bottom wall. At least one window is provided in the cover to allow infrared radiation to pass therethrough that is absorbed by interior surfaces of the base to cause an increase in a temperature within the enclosure sufficient to increase a rate of drying products located within the enclosure.
