    Diseño y construcción de un deshidratador de maíz mediante radiación solar para los productores del cantón Cevallos
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2024-02) Coquinche Alvarado, Juan Daniel; Guamanquispe Toasa, Jorge Patricio
    This project arises from the problems that exist for producers in the Cevallos canton during the corn dehydration process, a process in which they manipulate the corn outdoors, exposing it to the growth of bacteria or possible germination; Therefore, they require the dehydration process for conservation, consumption and seed. In the province of Tungurahua there is a global average of solar insolation that was used as an energy resource, a corn dehydrator was designed and built, information was taken that allowed determining the parameters for the design, using the INEN 2050:95 standard; The CONELEC solar map and the INHAMI meteorological station revealed the amount of global irradiation and the peak solar time; The selection of materials was carried out based on efficiency, budget and operating conditions, presenting the tunnel-type dehydrator. Using simulation and design software, the behavior of the components that are part of the heat transfer was presented. From the dimensions obtained, the dehydrator was built, with a capacity of 10 kg considering that the humidity must be reduced to 14 percent for 3.45 days. As a result, an operation and maintenance manual was created, providing added value to the production, storage and transportation chain of corn according to the level of impurities and humidity that govern the quality and price of the product in its future commercialization.

    The execution is carried out with the investigation of legal regulations that authorize the design and construction of eye protectors and that is legally permitted in Ecuador, this being the official registry RTE INEN 216, which cites the standard EN 166: 2001 as reference for the design and construction of eye protectors. In accordance with the beneficiary company, a design for "glasses with lateral protection" is established and focuses on optimizing conventional designs under the concept of less, moreover, providing greater protection of the eye area proposed by the standard mentioned with a product of three elements that are assembled by adjustment and without metallic pins. The final geometry was obtained after several designs that were captured in prototypes by means of molten deposition molding (3D printing) and served as a guide to visualize constructive details. Once the 3D geometry was established, the CAD design of the matrix for injection molding was carried out, where the parameters of the injection machines were used for the design of two injection molds, injection pressure parameters, closing force, and injection capacity define the geometry of the mold and number of cavities. Each element of the injection molds was built, with a manufacturing process by chip removal that allows obtaining each mechanized element. To then be assembled piece by piece and then mounted on the injection machine, where injection tests were carried out until the desired product was obtained.

    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2019) Velasco Alvarez, David Natanael; Carrillo Rosero, Carlos Mauricio
    For this project, the behavior of nickel with titanium production was evaluated as a band for a clean energy generator. The cable specifications used are 0.5 mm in diameter and 80ºC transition temperature, for the quality a transmission ratio of 5: 2 is considered. Once the relationship was established, the design of the pulleys was obtained obtaining the masses in a CAD software to be used to obtain the linear force of the circular movement. For the selection of the number of channels to be used, consider the transmission force of the nitinol wire through the Dinalloy factory, to be compared with the linear force obtained for each channel added. Once the generator is designed, 3D printing will be processed and used for the construction of pulleys, bases, protectors and supports, it will be used with PLA polymers. Once the construction is finished, the necessary tests will be carried out to obtain revolutions generated by the pulley system, voltage and amperage of the system, therefore, the connection of the large pulley shaft was made, which gave greater torque through a transmission coupling to the generator motor shaft. And measurements were obtained through a PID (Proportional, Integral and Derivative) in the large pulley of 50 to 60 rpm at a high temperature of 80 ° C and a compression temperature that was modified between 15 ° C to 30 ° C for a voltage of 1.12 V.
