Diseño y construcción de una majadora de plátano verde para la elaboración de empanadas y bolones a ser operada por una persona de la tercera edad

Abstract

In the present titration work, it is oriented in the design and construction of a cooked green banana masher machine, for making empanadas and bolones. It is intended for use in the elderly, with the aim of reducing the physical effort to perform this action. Chapter 1 details the basic concepts and theoretical foundations, starting with a brief description of the problems involved in performing the manual crushing process. It shows a brief historical overview of the raw material, to complement with the study of the mechanical and electronic components that are used in the construction of this machine. For the analysis and selection of viable alternatives, 3 options are presented with different materials and controllers, which automates and operates the equipment, as shown in Chapter 2. A weighting table is created that evaluates the best design alternative, ensuring reliability, low cost and high efficiency in equipment operation. In Chapter 3 we present the design and construction of the green machine, through a design software we proceeded with the choice of prototype assembly components, through the static analysis offered by the software we get the results of efforts, safety factors and movement of parts of the machine. As well as the maximum crushing capacity of the machine was determined will be 4 green bananas cooked on a perforated grid with dimensions of 0.2 x 0.12 m. The compressor has a power of ¼ HP that will supply a maximum pressure of 50 PSI of which only 8 will be needed to crush the green, driven by a double acting pneumatic cylinder, which will exert pressure on the grid, thus obtaining the desired product.
