Temperature ranges of 100 to 160 degrees will effectively kill bacteria and inactivate enzymes, although temperatures around 110 degrees are recommended for solar dryers. Too much heat especially early in the process will prevent complete drying. Rotate trays 180 degrees daily for uniform drying. Move dryer food to bottom racks. Store food in air tight jars or plastic containers, and do not expose dried food to air, light or moisture.
