Previous issue date: 2013-12-27 / Com o crescimento da popula??o e a necessidade do aumento do consumo energ?tico no Brasil e no mundo, ? not?ria a import?ncia do uso de energias tidas como renov?veis para suprir essa demanda. Pensando nisso, o estudo de fontes renov?veis, como a energia solar, ? uma op??o para resolver tal problem?tica. O projeto exposto vem como uma das alternativas de suprir essa problem?tica com o foco uso da energia para a coc??o de alimentos e diminuir o uso de fontes que poluem o meio ambiente com gera??o de g?s carb?nico tendo como outro foco a diminui??o do desmatamento e da desertifica??o, ambos origin?rios do uso da lenha e de combust?veis f?sseis como fonte de energia. Foram confeccionados dois prot?tipos feitos com tambores de polietileno caracterizando como uma atividade de reuso ou reciclagem j? que iriam ser depositados no meio ambiente. Os fornos foram testados para produzirem o assamento de alguns alimentos convencionalmente preparados em fornos convencionais a g?s. No mais eficiente dos prot?tipos a temperatura do absorvedor alcan?ou 120,8?C. Os tempos de assamento para tais alimentos foram superiores aos obtidos com o forno convencional a g?s, por?m competitivos com outros fornos solares mostrados pela literatura solar para assamento de alimentos. / With population growth and the need for increased energy consumption in Brazil and
worldwide, it is clear the importance of using renewable energies as taken to meet this
demand. Thinking that, the studies from renewable sources such as solar power is an option to
resolve such problems. The project has been exposed as an alternative to overcome this
problem with the use of focused energy to cook food and decrease the use of sources that
pollute the environment with carbon dioxide generation focusing on the secondary does not
increase deforestation, desertification, both of which originate from the use of wood and fossil
fuels as an energy source. For both two prototypes were fabricated for comparison, both being
made with polyethylene drums featuring as an active reuse or recycling, since the same would
be deposited in the environment. The ovens were tested to yield the baking of some foods
conventionally prepared in conventional gas ovens. In more efficient prototypes temperature
of the absorber reached 120.8 ? C. The baking times for such foods were higher than those
obtained with the conventional gas oven, but competitive with other solar ovens shown by
solar literature for baking food.
