Experimental Study of Integrated Solar Dryer with and Without Reversed Absorber and Reflector

Abstract

The aim of manuscript writing is to recommend a solar crop dryer with reversed absorber and reflector which collect the maximum possible solar emission. For experimentation, model was made adjustable such that it can satisfy the required conditions. The two types of solar dryer used are (1) Solar dryer without reversed absorber and reflector (2) Solar dryer with reversed absorber and reflector. The average collector efficiency ( $${\upeta }_{\mathrm{c}}$$ ), 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 as well as constants by graphical method. These values show that SD6 is more capable than another solar dryer. The experimental data are 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.
