Abstract—Solar drying is one of the oldest drying techniques in which solar radiation is used. Drying is an essential process in the preservation of agricultural crops and in industries, such as textile production, dairy processing, cement production, clay brick production, tile production, wood and timber processing, wastewater treatment and biomass treatment. Solar drying is another very important application of solar energy. Solar dryers use air collectors to collect solar energy. Solar dryers are used primarily by the agricultural industry. The purpose of drying an agricultural product is to reduce its moisture content to a level that prevents its deterioration. In drying, two processes take place; One is a heat transfer to the product using energy from the heating source, and the other is a mass transfer of moisture from the interior of the product to its surface and from the surface to the surrounding air. In short, we conduct a comprehensive review of summarize the research and development work for solar drying. It is hoped that this review work maybe valuable and appropriate for further development work.

Index Terms—Solar drying, solar energy, solar thermolysis.
