Diseño y construcción de un prototipo de molino pulverizador para la industrialización de Uncaria Tomentosa (uña de gato)

Abstract

The objective of this degree work was to design and build the prototype of a pulverizing mil of the Uncaria Tomentosa plant (Uña de gato), to industrialize its processing. Initially, with the deployment of the QFD, the following technical requirements were obtained: grinding capacity of 25kg/h and converting the Uncaria bark completely into poder. This work consists of the desing of Mechanical elements, the selection of Materials and the structural analysis. Regarding the mechanical elements, it was determined to use a 1 HP single-phase electric motor, an impact spraying system through paddles, a system of fixed and mobile blades and two hoppers (infeed /outfeed) with the capacity for an approximate mass flow. Of 25 kg of bark. Then, the mill bed was designed and dimensioned considering the total weight, ergonomics and ease of transport of the machine, where through a estructural analysis carried out in SAP 2000 and applying a total load of 34.74 kgf corresponding to the weight, ergonomics and ease of transport of the machine, the CES eduPACK software was used and it was determined that 304stainless steel is adequate to resist corrosión and protect the user’s health, when applying CAD software, it allows the designer to have a visualization of the geometry, dimensions and resistance of the machine prior to being built. Finally, it is concluded that the construction of the prototype by means of 3D printing allows the elements of the machine to be observed in a real way. For the construction of the spraying machine, it is recommended to consider the technical specifications and the plans made in this Project.
