Fabricação e estudo de um forno solar tipo caixa com capacidade simultânea de assentamento de vários alimentos

Abstract

Solar ovens utilize energy from the sun and through the greenhouse enable baking food, and thereby it's a source of use of clean and sustainable energy. It presents a solar oven constructed using MDF intended for baking food such as pizza, cakes, breads, hamburgers and others. Were presented Manufacturing processes and assembly of the proposed solar oven which has a low manufacturing cost. The main characteristic of the proposed solar oven is the ability to cook various foods simultaneously. Tests were conducted for the baking of various foods, with varying loads. In one of these tests were baking eight cakes in only eighty minutes and the results were compared with the various types of solar oven shown the literature. The results of the baking tests demonstrated the feasibility of the solar oven and their competitiveness in relation to solar ovens manufactured and tested in Brazil and in the world., due to its ability to bake a significant load of food, with an efficiency of approximately 80%. Were analyzed the thermal viability, where maximum temperatures of 140,5ºC were achieved, and the economic viability of the solar oven that can provide the socialization of the use of solar energy for underserved communities, and can become a source of generation of employment and income. The proposed solar oven was tested to produce the baking of pizzas, cakes, bread, breaded, cheese, acarajés, meat, sausage and meatballs.
