Diseño y construcción de una máquina clasificadora de tomate riñon – variedad daniela de 80 cartones de 23 [kg/h] de capacidad.

Abstract

In the mechanical engineering career, the need to design and construct machines that facilitate the resolution of problems in the Yaruquíes parish belonging to the Riobamba canton grow tomatoes (tomate riñon) and their classification is carried out manually, without food manipulation norms, such a way has seen the need to manufacture a sorting machine. We use a methodology to find the best alternative solution, which we start from the study of art, with which we perform a previous analysis, guiding us with surveys, a field study, tomato characteristics, classification methods. We proceed to the conceptual design, requirements based on the QFD matrix. Design the elements of the machine, selection of the best alternative, study of elements, use of formulas for the sizing of components. Detail design presents the necessary documents for the manufacturing, as they are parts blueprints, calculation memories. As a result of the evaluation, the machine of the tomato sorter in correspondence with the projected capacity of 80 cartons of 23 kg / hour whose output variables were the time and the effectiveness of classification was obtained a time of 0.82 hours and a quality of classification of 98.85% fulfilling thus the requirements of the sponsor. It is recommended the product should be in a 60% maturity percentage. We conclude that the machine is efficient and not very expensive compared to the machines outside. We recommend that you carry it from one place to another with the greatest possible care so that its components do not misalign and lose efficiency.
