Development and Performance Evaluation of a Dual Heat Dryer; a Renewable Energy Technology for Sustainable Processing of Agro-Produce

Abstract: Rural agricultural sector in developing countries such as Sri Lanka is still lacking efficient and cost effective devices for processing of agricultural produce. A dual heat dryer which utilises rice husk and solar energy for thermal energy generation required for the drying process was designed and developed at the Institute of Post Harvest Technology (IPHT), Sri Lanka for dehydration of agricultural produce. Performance evaluation of the dual heat dryer gave promising results for adoption by the farming comm… Show more

“…However, the low-cost drying methods should not degrade the quality of the final product. Hence, there is a necessity to introduce efficient and cost-effective drying methods utilizing renewable energy sources in order to benefit the remote rural communities [3]. Since the most of fruits are grown in hot sunny areas of Sri Lanka and they are harvested during the time of the year that solar radiation is abundant, solar drying is the most promising and cost-effective method for dehydration of fruits and vegetables for remote rural agro communities.…”
