Quick Answer
To effectively sun dry food, you'll need a few essential tools such as a clean, flat drying surface, a mesh screen to allow air circulation and keep out insects, and a thermometer to monitor temperature.
Essential Drying Surfaces
A clean, flat drying surface is crucial for sun drying food. Ideally, this surface should be made of a food-grade material such as stainless steel, wood, or plastic. A 1/4 inch or 6 mm gap between the surface and any surrounding structure is necessary to allow air to circulate, promoting even drying. Examples of suitable surfaces include a drying rack, a wooden plank, or a metal tray.
Sizing and Positioning
When selecting a surface for sun drying, consider the size of the food items to be dried. A larger surface area will accommodate more food, but it may also require more space to allow for air circulation. Position the surface in a location that receives direct sunlight for at least 6 hours a day, ideally with some shade to prevent overheating. An east- or west-facing surface is ideal, as it receives gentle morning and afternoon sunlight.
Additional Equipment
A mesh screen is essential for preventing insects and dust from contaminating the dried food. Choose a screen with a mesh size of 1/8 inch or smaller to keep out even the smallest insects. A thermometer is also necessary to monitor temperature, which should not exceed 140°F (60°C) for most types of food. Regularly clean the drying surface and screens to prevent bacterial growth and maintain hygiene.
