摘要：The global world requirements for solutions towards nutrition and food production problemsfor rural and remote areas are in constant growth. The limitation of resources remain itsweakest points, water, food and energy are inextricably linked. In the present work, anexperimental study conducted to deal with the problem of energy resources lack for foodcooking and water boiling for drinking in remote area providing a technique that uses solarenergy. A parabolic solar cooker was designed, constructed and tested under the Tunisianclimatic conditions. Theoretical models were proposed to simulate the thermal performancesof the solar cooker for both processes. The predictive models take into consideration theheat transfers during the process of meat grilling and water boiling and the variation of theclimatic conditions. The experimentations carried out for the process of grilling meat andhighlighted that the solar cooker is able to reach temperatures levels comparable toconventional cookers. The solar cooker reached temperatures above the 300°C which allowsto grill the meat in an acceptable cooking time. Simulations results show that the achievedtemperature by the solar cooker is suitable for different cooking processes and waterdisinfection by boiling. In addition, the proposed solar cooker present a solution in order toreduce the environmental impact of conventional fuels consumption. The solar cookerprovides a yearly thermal energy of around 317.63 kWh. A 127.05 kg of wood could besaved which corresponds to equivalent CO2 emissions of 123.87 kg per year.
