Abstract—It presents a solar oven for baking food, manufactured from a thermal box of EPS. The solar oven proposed is a prototype of solar concentration for the operation of baking foods such as breads, cakes, pizza among others. The main innovation of the work is the use of EPS cooler, widely available, low cost and with a structure already defined and manufactured, avoiding the production of mold to get the box. The inside of the box EPS enclosure baking oven, was coated on the bottom and side sheets by mirrors forming the profile which gives the greater concentration of solar radiation. Above the floor of the oven is system with plane mirror reflector, which moves according to the movement of the sun, directing the solar rays into the oven where the food displaced into the baking. Are presented results of tests that diagnose the viability of using the solar oven for several types of food. Compared are the times of baking food with those obtained for other types of solar ovens presented by solar literature, also as compared to gas conventional oven. Preliminary tests have shown the feasibility of using such solar oven, temperature levels being achieved adequate for the purpose proposed, affording the baking of various foods. The tests show that the solar oven reached the maximum temperature of 123.8°C and baking various foods such as pizza, lasagna, cake, bun, and other in an average time 50 minutes. Proved the feasibility of use of the oven proposed.
Index Terms—Solar, solar oven, EPS box, baking food, low cost.
