Optimización del proceso de trillado y ventilado mediante la repotenciación de maquinaria en la empresa Asualinium de la ciudad de Ambato.

Abstract

The present degree work of Repowering of the Thresher and Ventilator for the optimization process of the threshing of the Quinoa for the company ASUALINIUM, is repowering said machines that are inoperative due to the initial damages in its mechanical system, this accompanied by a lack of interest for its immediate repair that led to the progressive deterioration of it. This project seeks the start-up of the thresher and ventilator through the repowering of its systems. To carry out the repowering, the initial state of the mechanical parts was analyzed, in order to determine which, one should be replaced or require an appropriate design. For the selection of belts and pulleys, the type of belt and the appropriate diameter of the pulley are redesigned, which will exert an optimal transmission and thus improve the service life of the bearings. The different materials for the threshing drum shaft were investigated according to the mechanical properties and applications, which was an AISI 1018 (Transmission) steel. The durability calculation of the axis was performed and it was acceptable within the established ranges. Optimizing the threshing and ventilating system of quinoa in this way. The machines were re-powered, tests were carried out to determine their correct operation and the comparison with the threshing and manual ventilation process was carried out, determining the effectiveness of the thresher and fan, when threshing 46,80 kg of quinoa, comparing with the time of manual threshing for the same amount with a result of 4 hours 28 minutes and 30 seconds, while when throwing, the same amount of threshing in 7 minutes and 30 seconds compared with the manual winnowing time for the same amount with a result of 3 hours 30 minutes and 20 seconds. Among the advantages of the thresher and the quinoa fan are the considerable reduction of production times and the number of operators, in order to obtain a clean grain without impurities.
