Energy and exergo-environmental (3E) analysis of wheat seeds drying using indirect solar dryer.

Food insecurity is becoming a big problem due to the continuous increase in the population, for which there is a requirement of effective drying method for the storage of agricultural items which can solve this problem at global level. Hence, the present study deals with the evaluation of energy, exergy, and environmental parameters of low-cost indirect solar dryer with paraffin wax as energy storage material in rural areas for drying of wheat seeds to check its thermodynamic as well as environmental feasibility. The wheat seeds were dried in solar dryer from initial moisture of 20.
