Abstract
The discrepancies of using open-air sun drying method for drying agricultural produce and to preserve other variety of food items still exists. In the present time, to get rid of all the disadvantages associated with it, many comprehensive design structures of solar food dryer and their modification has been presented and investigated This research paper highlights the energy analysis performed on a latest design of a solar food dryer in which impinging jet mechanism and fins are clubbed together. The enhancement in heat transfer under preferred range of important parameters investigated namely mass flow rate (ṁ), Reynolds’s number, Flow-wise pitch ratio, Fin-spacing ratio etc. It has been observed that this new design of solar food dryer is more efficient and user friendly. The result has been plotted for Reynolds’s number (Re), mass flow rate (ṁ). The findings for this new design of solar food dryer reflect that temperature range of air coming out from outlet section is in the range of (45˚C-55˚C) which is undoubtedly good.
