This work involves the experimental investigation of solar drier integrated with HSU for crops. The loading capacity of the unit is 1kg and radish is used as a crop. In HSU, PCM (Paraffin Wax) is acted as the heat storage medium. The experiments were conducted with the radish having the initial moisture content of 95% wet basis from to be removed 10% during November 2016 in Salem, Tamil Nadu. The nominal surface area of all types of absorber plate is 0.5 m2 but effective surface area varies with configuration. The drying time and efficiency were taken around 15.6 hours and 2.6-12.13% respectively with the flat plate but it varies up to 10-13 hours and 4.2-16.4% respectively for other design considerations. Also, the quality of the dried radish will be high superior compared to open sun drying.
