Abstract

The study aims to construct, develop and evaluate the performance of solar box cooker viz non-modified and modified. A box-type solar cooker was constructed, and the cooker was supplied with a solar concentrator with dual tracking system to improve the gained heat. The tests have been carried out in Shubra El-Kheima, Egypt (Latitude 30 o 11' N, Longitude 31o 24' E). The solar cookers were not loaded, and loaded with 0.5, 1.0 and 2.0 liter of water. The modified box was filled with different volumes of rice and 210 g of biscuit. The thermal performance was evaluated by using first figure of merit F1, second figure of merit F2 and energy efficiency. The calculated values of F1 was 0.108 and 0.087 oC.m2/W for modified and non-modified cooker, respectively. The value of F2 was 0.262 and 0.089 for modified and non-modified cooker, respectively. The modified cooker achieved a higher temperature than the non- modified cooker by about 23% at the maximum water mass of 2 l. The total required time was about 255 min for cooking a 1000 g of rice, and 90 min for baking a 210 g of biscuit. The cost of the modified cooker saves about 20.8 % of the operation cost of the traditional gas cooker. The maturity of cooking of solar-cooked rice and biscuit was checked, the values of hardness for cooked rice and baked biscuit was agreed with the references values.
