LAVADOR DE CAFÉ: estudo de caso, buscando melhorias no equipamento

Abstract

In order to produce high quality coffee, you cannot forget or diminish the importance of any of the operations from planting to reaching the consumer. Washing coffee is one of the product processing procedures that can and should receive improvements. Thus, the objective of this work was to seek improvements in a washer model from the company VN Máquinas in the municipality of Varginha, in order to reduce the final cost of the equipment, increase the sales index and increase the interest of small producers as a result. . For this, information was collected about coffee and all its processing, analyzing each stage and highlighting the main object of this study, the coffee washer. After joining all the theoretical framework, specific data of the VN 80-2 model to be modified were collected, through interviews and visits to the company's headquarters. All the data obtained were analyzed and systematized in order to conceive the necessary changes in the prototype. A new belt was dimensioned, calculations of power loss, torque and rotation were performed, as well as the rotation check between the pulleys. After executing the calculation report, it was possible to design a new washer model, the VN 90-S. This was able to meet the initial expectations of the project, by reducing materials in its production, increasing efficiency, managing to maintain its characteristics and reducing the final cost of the equipment.
