Experimental investigation of solar‐powered food steamer based on parabolic dish concentrator for domestic applications
Steam cooking is beneficial over other cooking techniques like boiling since it preserves more vitamins lost during other methods. In this study, a novel solar food steamer (SFS) based on a parabolic dish concentrator (PDC) is designed and constructed for domestic food preparation. A straightforward fabrication process of a 2.626 m2 PDC with design calculations is also presented. The system's instantaneous energy and exergy efficiency evaluation has been examined from different tests over three consecutive days. The system's high energetic and exergetic efficiency was achieved in the case of sweet potato, that is, 72.83% and 15.14%, respectively. In the case of dried chickpeas, the maximum steaming duration of 70 min was attained, along with an energy efficiency of 47.74% and an exergy efficiency of 10.07%. In addition, an economic analysis was performed to determine the payback time in terms of cost and utility. The payback time for the proposed method is 2.4 years. The SFS may save 43 kg/month of carbon dioxide from escaping into the atmosphere; it can be considered an environmentally valuable device.
