“…A typical mixed-mode natural circulation solar-energy dryers is similar to indirect mode dryer but incorporates glazed surfaces to the drying chamber (Archuleta et al, 1983;Ayensu and Asiedu-Bondzie, 1986;El-Sebaii et al, 2002;Exell et al, 1979;Mustayen et al, 2014;Ong, 1979;Roberto, 1984;Sharma et al, 1986;Simate, 2003;Eissen and Miihlbauer, 1983;Ayensu and Asiedu-Bondzie, 1986).…”

Drying reduces the moisture content of harvested crops thus slowing decay processes to enable longerterm storage. Solar dryers contain the crop being dried, to enhance solar energy collection incurring lower crop losses than are associated with open-sun drying and recurrent costs than are inherent to uses of fossil-fuels for drying. The influences of key environmental, operational and design parameters for solar dryers are discussed including: (i) psychrometry of drying processes and ambient conditions, (ii) how initial crop properties are converted to final desired product attributes, (iii) feasibility of using powered components such as fans and (iv) air-heating solar collector selection.

“…Most of the research in batch drying processes has targeted the effect of temperature and air velocity as primary influencing parameters for the quality of dried products while the lack of uniformity in air flow is a crucial factor. Taking air distribution as primary design parameter has been the main objective in past few research (Adams and Thompson, 1985;Ayensu and Asiedu-Bondzie, 1986;Mathioulakis et al, 1998;Kiranoudis et al, 1999;Shawik et al, 2001;Mirade, 2003;Babalis et al, 2005;Margaris and Ghiaus, 2006;Gül ah and Cengiz, 2009;Amanlou and Zomorodian, 2010;Jacek et al, 2010;Tzempelikos et al, 2012;Darabi et al, 2013). Therefore, the design of airflow is one of the most important factors in batch type dryers.…”

“…The choice of a specific type of storage method depends mainly on the temperature range, thermochemical properties and cost. Most of the researchers purposed rock bed heat storage techniques because of the lower cost and easy availability of rocks [39][40][41][42][43].…”

In solar drying, the moisture content of a product is reduced through the use of sunlight. Solar drying is practiced since civilization for the drying of crops. The dried crop has a longer shelf life and requires less storage space. For crop drying, hot air is required in the moderate temperature range of 40 to 75℃. Solar dryer makes it possible to obtain better product quality. Over the past 20 years, numerous experimental projects have been carried out in the field of solar dryers. Most conventional dryers are not able to operate continuously during the off sunshine time. However, attempts were made to develop uninterrupted solar drying systems by incorporating an energy storage facility and a hybrid mode of operation. Sensible and latent heat storage methods are widely used to store solar energy. Heat storage materials store energy in the form of heat during sunshine and release it whenever it is required. Biogas backup, Chemical heat pump, Photo Voltaic, and Fluidized bed methods were integrated with solar dryers for uninterrupted operation. In this article, the discussion is made about different dryers. Also, the challenges and scope in the area of the solar dryer are highlighted.
