“…According to the findings, cast iron reached the greatest temperature and, in comparison to granite, cooked food faster and with fewer heat losses. A solar cooker storage pot was positioned in the middle of two linked parabolic dish collectors in an experiment conducted by Wollele and Hassen (2019). The solar cooker storage pot's ingredients included rock and engine oil.…”

Gari roasting is an energy-intensive process that is commonly used to produce gari, a popular food in Nigeria made from cassava. Traditional gari roasting methods use firewood as an energy source, which is not only inefficient but also harmful to the health of those who inhale the smoke (who are mainly women and children in rural communities) and contributes to deforestation. This work aims to investigate the use of a developed garri roasting system driven by a concentrated parabolic solar collector. Important garri roasting food chain data was obtained from a work-study at a rural community: temperatures, moisture content. The garri roasting temperatures range between 85oC - 100oC. The parabolic dish solar collector was designed and fabricated to achieve temperatures between 1180C-154oC at optimum tilt angles at Port Harcourt (4°54' 22.86''N, 6°55' 27.52''E) climatic conditions. The focal length ranges between 50mm-80mm, and the fluctuation of the focal point position was considered for the thermal storage system design. Gravel was used as a thermal storage and heat transfer enhanced through small internally placed mild steel rods. A theoretical estimate for total fry time per batch was 8.5 minutes. The garri roasting experiment was conducted for three days with favorable weather conditions, with an achieved maximum temperature of 101oC. This innovation is an important step in addressing the health risks associated with traditional gari roasting methods, and in moving towards zero-emission and zero-poverty innovative systems.

Energy-saving technologies and equipment 31 in Indonesia comes from fossil energy sources. Until 2019, power plants in the country are still dominant from conventional energy sources, including coal (50 %), followed by natural gas (29 %), fuel (7 %). While the use of renewable energy is only about 14 %, and for solar energy, utilization is less than 1 % [1]. Currently, the largest energy user in Indonesia is the industrial sector by 36 %, the transportation sector by 40 %, the household sector by 16 %, and the commercial sector by 6 %. 1. Introduction Solar thermal energy is one of the potential energy to be managed and developed further as a source of energy reserves, especially for countries located on the equator, including Indonesia, where the sun shines throughout the year. The potential of solar power in this region can reach 5.1 kWh/m 2 /day (Eastern Indonesia) and 4.5 kWh/m 2 /day (Western Indonesia). However, the majority of energy use

“…The team evaluated the thermal performance of the sensible heat storage materials like sand, stone pebbles, iron balls and iron grits, and found that the food was well-cooked using sand, iron grits and stone pebbles, and was partly cooked using iron balls. Wollele and Hassen (2019) (31) experimented the performance of thermal energy storage incorporated within a layer the cooking vessel. In the absence of the concentrators, the integrated cooking vessel raised water temperature to 355k (82℃) within 40 minutes.…”

This paper proposes solar energy as a viable alternative to biomass fuels for cooking, introducing a collapsible parabolic solar cooker designed to regulate heat production. The collector is divided into three sectors, with a specific condition for effective convergence of reflected radiation. The total concentration ratio is 89.4, with the primary sector covering 42%, while sectors 2 and 3 occupy 29% each. In the analysis ASAE protocol was employed. The results obtained from the ASAE S580.1 test revealed a range of cooking power values, with a minimum of 215.5 W and a maximum of 280.9 W. The single measure of performance of the cooker was gauged at 234.17 W. Regarding the Standard Stagnation Temperature, it was observed that a reduction of the collector area by 0.343݉ଶ resulted in a temperature decrease of 59.5℃. The highest recorded SST for the entire solar cooker (when all three sectors were expanded) reached 279℃.
