Solar Food Drying is one of the most practical methods of preserving food items, especially out at sea. This Solar Food Drier (SFD) is best used on boats, hung directly below the boom. The SFD is comprised of four racks covered with a black acrylon tarp. When hung up it harnesses solar heat, warming up the entire drier. Vents, located on the top will help regulate the temperature. Enjoy dried fruits, granola, cookies, kelp and fish without any ice or electricity!
