The aim of this manuscript is to recommend a solar crop dryer with reversed absorber and reflector which collects the maximum possible solar emission. For experimentation, the model was made adjustable such that it can satisfy the required conditions. Two types of solar dryers are used: 1) solar dryer without reversed absorber and reflector; 2) solar dryer with reversed absorber and reflector. The average collector efficiency (ηc), drying efficiency (ηd) and the picking efficiency (ηp) of multi-pass SCD with reversed absorber and reflector (SD6) values were 34%, 49% and 64% respectively. Excel software was used to find the changes in moisture content with the time and constants by graphical method. These values show that SD6 is more effective than any other solar dryer. The experimental data is more suitable for Pages’ model than other models. Pages’ model gives the best results with the maximum value of R2 and the minimum value of MBE and RMSE. It has been found that SD6 is the most effective solar dryer and can be used to dry other agriculture food products also.
