Verma Rekha and Parvez RaziaThe pooled average time taken in roasting groundnuts in BSCAl and BSCSS was24per cent and 19per cent less than PSCSS and 21per cent and 15per cent less thanPSCAl respectively.The statistical analysis revealed that the effect of seasons and cooking pot metalswere highly significant in rise of cooking temperature in both the tested solar cookers.At the same time box type solar cooker gave highly significant higher temperature risethan parabolic solar cooker in roasting of groundnuts in all the three seasons and bothmetallic pots. Similarly aluminum metallic pot gave highly significant temperature risethan stainless steel pot in both the tested solar cookers and all the three seasons. Thetemperature rise for roasting of groundnut was also highly significant in summer thanwinter and rainy seasons and in winter than rainy seasons in both tested cookers andmetallic pots.The similar trends were observed in time taken for roasting of groundnuts. Thusfrom the study it may be concluded that both the solar cooker gave best results forroasting of groundnuts in summer season with aluminum pot, However, box type solarcooker was found better than parabolic cooker because roasting of groundnuts tookmore time (204-213min.) in roasting than rice and orientation of cooker has major effecton solar radiation concentration in parabolic solar cooker.The aluminum pot metal gave better result than stainless steel because thermalcapacity of heat of aluminum is better than stainless steel.CONCLUSIONFrom the results summarized above, it can be concluded that both solar cookers(BSC and PSC) gave better performance during summer in comparison to other seasonsand also Al cooking pots were best in rice. Better performance of Box solar cooker thanParabolic solar cooker in preparation of Roasting of Groundnuts.ACKNOWLEDGEMENTIt is with the deepest sense of gratitude and indebt ness that I want to place onrecord my grateful thanks to my esteemed Advisor, Dr. (Mrs.) Razia Parvez, AssociateProfessor, Department of Family Resource Management, Halina School of HomeScience, SHIATS Allahabad.35
