“…Here, we clarify the concept of solar cookers because this term can include different types of this general concept. We may refer to some classifications such as the one in Aramesh (Figure 1) [28]. This classification is based on how thermal energy from the sun is transferred to the cooking vessel.…”

This work reviewed the state of the art concerning solar cookers and dryers used in food processing. The general description of solar cookers and dryers was presented, with a specific attention to the equipment where the cooking takes place with the contribution of the direct sunlight. Some insight about the history of design and development of devices that use solar light to process food were provided. The possibility to store the heat produced by solar light using Phase Change Materials was analyzed. Moreover, some “case-studies” were revised and discussed, in which solar light is efficiently used to dry or cook food, focusing on the quality of the food in terms of nutraceuticals content. The analyzed literature points out the necessity for further research about the effects produced by direct solar rays on different foods. The reliable data on this aspect will allow assessment of the quality of food transformation by solar cookers and dryers, adding a strong incentive to the development of such devices, up to now primarily motivated by energy-saving and environmental issues.

“…Owing to the practical goals, the shape of the reflector is established in such a way that the concentration of the light is constantly made exterior of the reflector, either on the northern sideways or the southern sideways. In such a way, the reflector concentrates the light at its focal point inside the building while it remains outside perpetually [1,17,23,27,28].…”

This research problem reveals the experimental investigation at a pressure of 1.5 bar and temperature of 120°C for the medium thermal applications utilizing the four Scheffler reflectors with 16 m 2 surface area each. The Scheffler collector associated with absorber plate of mild steel of size, 0.45 m diameter, and 0.025 m thick was assessed in June 2018. The variation in solar beam radiation over the entire day was observed from 840 W/m 2 to 1278 W/m 2 , while, the absorber plate temperature was recorded within the extent of 116-195°C, however, the maximum heating temperature was measured 129°C at the end-use. The Scheffler collectors performed appropriately in the morning and evening time with substantial heat loss factor and lower optical efficiency factor. The energy efficiency of 59.28% has been achieved which is higher as compared to the parabolic solar concentrator. The higher concentration ratio of the Scheffler collector indicates it as an efficient substitute to replace fossil fuels. The system is viable for more than 1600 kWh/m 2 yearly solar potential while the cost of heating is greater than 0.05 $/kWh for them. This paper concludes that the Scheffler reflector is the most promising solar technology for the medium-temperature applications.Cite this article as: Kumar A.

“…Geometry types and designs of solar cookers are, in principle, classified into three types, namely (1) concentrator type, (2) box-type designs, and (3) indirect types. Also, the classification of solar stoves into four types is (1) box-type solar cookers, (2) concentrating-type or reflector cookers, (3) heat-accumulating solar cookers, and (4) solar steam cookers [8][9][10][11].…”

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
