Solar energy has found its widespread use in direct conversion into electricity either by photovoltaic conversion or through thermal energy, reduction in post-harvest losses, and crop drying. Solar Drying Systems analyzes the fundamentals, principles and applications, heat transfer, elements of drying and solar dryer designs, and related modeling and analysis aspects of solar energy. Discusses both technical and policy-related issues Explores up-to-date status reviews of different solar drying systems Reviews the highlights of present and future solar drying options Includes many figures, solved examples, and tables with problems/exercises at the end of each chapter This book is aimed at senior undergraduate and graduate students in energy engineering.

As perhaps the most promising of all the renewable energy sources available today, solar energy is becoming increasingly important in the drive to achieve energy independence and climate balance. This new book is the masterwork from world-renowned expert Dr. Soteris Kalogirou, who has championed solar energy for decades. The book includes all areas of solar energy engineering, from the fundamentals to the highest level of current research. The author includes pivotal subjects such as solar collectors, solar water heating, solar space heating and cooling, industrial process heat, solar desalination, photovoltaics, solar thermal power systems, and modeling of solar systems, including the use of artificial intelligence systems in solar energy systems, modeling and performance prediction. *Written by one of the world's most renowned experts in solar energy*Covers the hottest new developments in solar technology, such as solar cooling and desalination*Packed with quick look up tables and schematic diagrams for the most commonly used systems today'

This training manual is the outcome of an ILO regional project on the development and application of appropriate food-processing technologies. During the project, extension workers from four developing Arab countries were trained in techniques of sun and solar drying. The manual provides clear and detailed information on the basic theory and practice of sun and solar drying of various food products (fish, fruit, vegetables and grains). It discusses the type of information needed to determine whether solar drying is feasible and appropriate in particular cases, and, with an explanation of how the sun's energy can be harnessed, outlines basic drying theory. Several different types of dryers - cabinet, tent, paddy, hybrid - are described and some guidance is given on their construction. Information is also provided on the preparation of the raw materials before they are dried and on packaging techniques for the dried product. It is hoped that agronomists, technologists and rural development trainers will use the information to encourage farmers and rural artisans to adopt these food-processing techniques.
