Development and Evaluation of Multi Reflector Foldable Type Solar Cooker

Abstract

A multi reflector foldable type solar cooker using locally available material was developed and evaluated for its thermal and cooking performance. It facilitates the wider utilization and adoption of solar energy for cooking the food in the household sector as well as in the outdoor during the picnics, parties, outings etc due to its foldable nature and light in weight( 2 Kg). The first figure of merit and second figure of merit was found to be 0.093 and 0.232 respectively. The time required for cooking the commonly used food item was found to be 75 to 110 minutes.  The results obtained were competitive with standers box type solar cooker.
