| The tobacco drying greenhouses, in general, are made without any coating that ensures thermal insulation and avoid heat losses, resulting in a large consumption of firewood during the drying of the tobacco. The study aims to develop an economically viable project to the producer, to avoid excessive heat loss through the walls and ceiling of a tobacco dryer, aimed at fuel economy, reduced drying time and reduces costs in process. For the current project, we considered changes of Brazilian theoretical mode, where we developed a thermal insulation system in a dryer, reaching satisfactory results, with a large reduction in energy losses and firewood consumption, resulting in a decrease in the costs of the proceedings in general. Thus, began for the development... |
