Diseño y construcción de una máquina para lavar y clasificar papas para la empresa Cereales Ambateños

Abstract

The technical project has been carried out due to the need that arises among potato farmers and merchants in the province of Tungurahua, since the work of choosing and classifying potatoes, as well as washing them is tedious and time consuming, in addition to that occupies personnel, which translates into costs for the farmer who owns the crop. The goal of this technical project is the design and construction of a machine that classifies and washes the harvested potato, reducing time and costs for the producer. Regarding the methodological part, parameters have been decided such as the number of potatoes to be classified and washed, the time that these processes will take, and the material that the machines will use is selected. Then the respective structural calculations were made through the CAD Software, deciding efforts, displacements, reactions, safety factors, among other parameters. Finally, the machine was built according to the model and the plans made previously, in addition to the fact that corrections were made for errors that were detected during the functional tests. As results, a system has been obtained in which 9000 kilograms of potatoes will be classified and washed in 8 hours, in addition to reducing the number of people used for these processes, which is usually varied according to the production in the manual method, to only 2 people controlling the operation of the machine.
