Drying crops by solar energy is of great economic importance the world over, especially in India where most of the crops and grain harvests are lost to fungal and microbial attacks. Proper drying could easily prevent these wastages, which enhances storage of crops and grains over long periods. India is blessed with abundant solar energy all the year round. Drying is one of the important and most energy consuming processes in the food-processing, chemical, printing, fabric dying industries, etc. In farmer level drying is being done on open yards without any good hygienic conditions. The objective of this project is to modify design of a forced convection indirect solar dryer and its performance test on Grapes and etc. The hot air passed to the required place, so that the moisture contents in the place was removed. It offers a better control over drying and the product obtained is of better quality than sun drying. Solar Dryer Can be operated at higher temperature, recommended for deep layer drying. In this project designed, New solar dryer with Phase Change Material for off sun shine timings. 1.2*1 m2 area of conventional solar dryer designed with 3.5kg of PCM (Sodiumthiosulphate pentahydrate and Disodium hydrogen phosphate decacohydrate ) for 5kg of drying products. The Performance are experimentally conducted in on shine and off shine periods. The solar dryer consists of different components such as wood, Glass ,Copper tube, Metal Sheet, Galvanization Iron and Phase Change Material.

Solar Collector, drying chamber, Copper tubes, phase change material and drying products.
