Food losses in the developing world are estimated to be 50 % of the fruits and vegetables grown and 25 % of harvested food grain (Burden, 1989). Food preservation by drying can reduce wastage of a harvest surplus, allow storage for food shortages, and in some cases facilitate export to high-value markets. This paper presents the characteristics of three solar driers. A 15 US $ tent drier, a 400 US $ box drier, and a 5,000 US $ tunnel drier are discussed. References are given to solar drier vendors and sources leading to numerous other solar drier designs. For an overview of solar drying theory and equipment classification, refer to “Solar Dryin
