Keep it simple. Contraptions abound but all you really need to dry foods are heat and good air flow. Here is one of many setups using fabric and a vented hard surface. I’m using the tray from an old dehydrator that quit working but any vented hard surface such as pot strainers would work. For the fabric, use tulle netting with a fine enough mesh to let air through but keep bugs out. Fold in thirds, overlapping the opening, and sew/serge the edges. Stick it in the sun and that’s it! Don’t forget to bring indoors nightly!
