Diseño y construcción de un pulverizador de productos deshidratados, con capacidad de 30 kg/h para un sistema de producción agroindustrial

Abstract

The purpose of this degree work was to design and build a sprayer for dehydrated products, with a capacity of 30 kg/h for an agro-industrial production plant. Using the quality function deployment (QFD) methodology to obtain specific technical parameters and the best machinery alternative through the evaluation of criteria, where it was obtained that the best alternative is an impact blade pulverizer, with these data the design was carried out of detail, made up of the choice of material, the design and selection of machine elements, and structural analysis using software. With these results, the materialization design was carried out, where models of the previously designed geometries were prepared using computeraided drawing software (CAD), later manufacturing plans were made, in which the technical specifications, dimensions and processes required were detailed. For manufacturing, with these models a design validation was carried out using computer- aided engineering software (CAE) of critical elements of the sprayer, the analysis parameters were determined and it was observed that the design carried out was consistent with the results obtained, it allowed the construction and assembly of the pulverizer, with the prototype a test protocol was carried out where the operating stages of the machine under normal operation were evaluated and the correct performance of the grinding process was demonstrated. It is concluded that the methodology used to develop the project was adequate, since the specifications of the sprayer were established, and the type of grinding was correctly selected, in addition, each of the constituent elements of the sprayer was sized and its correct performance was corroborated. It is recommended to install the machinery on a flat surface and not increase the operating speed or the preset load, since it can cause accidents and excessive material loss.
