Resumo: | The crop Coffee demands investments to the machines development, which it enables the processes ofpost-harvesting, becoming them faster, meanwhile improving the working. The use of stationary layer dryers are responsible for good results at drying and product quality, but it requires a constant revolving, in order to homogenize the grain mass and improve the air distribution inside the drying chamber. The shortage of workmanship, associated to the need of constant revolving and the heavy working conditions, it becomes it indispensable to mechanize, in some way, this step. The agricultural machine design is considered of great complexity, regarding it must be concerned with the interactions among the operator, machine and environment. When designing a machine, the experience and the dominion of several standpoints have to be interpreted clearly. With the increasing competitiveness on the consumer market and agricultural machines, several companies have joined the research centers, because in general, do not make use of systematic procedures during the project, which can result in failures during operation. This article aimed to design and build a semi-mechanized revolving prototype used to mix the coffee beans. The revolving prototype with the helical screw principles proved to be able to performing the grains transport efficiently. |

A utilização de secadores de camada estacionária resulta em bons resultados quanto à secagem e qualidade do produto, mas necessitam de revolvimento constante para homogeneizar a massa de grãos. A escassez de mão de obra associada à necessidade de revolvimento constante e as pesadas condições de trabalho obrigam a mecanização desta etapa. O projeto de uma máquina agrícola é considerado de grande complexidade, preocupando-se com as interações entre o operador, a máquina e o ambiente. Ao projetar uma máquina, as experiências e o domínio sobre os diversos pontos de vista tem que ser interpretados de forma clara. Com o aumento da competitividade, diversas empresas de máquinas e implementos agrícolas tem buscado os centros de pesquisa, pois em geral não utilizam dos procedimentos sistemáticos durante o projeto, o que pode resultar em falhas de operação. Objetivou-se com a realização deste trabalho projetar e construir um protótipo revolvedor semimecanizadopara realizar a mistura dos grãos de café. O protótipo revolvedor com o princípio de rosca helicoidal se mostrou capaz de realizar a movimentação dos grãos com eficiência.
