    Análisis de parámetros de fabricación en pellets de aserrín de eucalipto para mejorar sus características de combustión
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2025-02) Sanchez Castro, Felix Xavier; Cabrera Anda, Santiago Paúl
    The manufacture of sawdust pellets has gained popularity in recent years by taking advantage of waste from the wood industry. The quality of the pellets can vary significantly depending on the manufacturing processes used. Therefore, the present work focused on improving the final quality of the pellets by adding binder to find improvements in compaction and measure their quality during combustion. The humidity percentage of the sawdust was modified through a drying process, in which both temperature and time were varied. For the production of the pellets, a cylindrical manual compaction matrix was used, applying a pressure of 30 bars and cassava starch as a binder. Three different drying conditions were carried out: natural drying (room temperature) for 24 hours; drying at 105 degrees Celsius for 30 minutes; drying at 105 degrees Celsius for 4 hours. The results showed that, when using eucalyptus sawdust pellets dried at 105 degrees Celsius for 4 hours, the best combustion characteristics were achieved, since flame areas of 3,93 square centimeters were obtained, with flame heights of 1,97 centimeters, temperatures reached 580 degrees Celsius for 100 seconds, which favors a more efficient combustion. Likewise, volatile contents of 76,34 percent, ash 0,25 percent, fixed carbon 23,40 percent and a CO concentration of 207 ppm were obtained, which indicates a cleaner combustion.

    Análisis térmico del proceso de secado de gelatina para determinar su eficiencia en la empresa Prodegel S.A.
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2022-09) Acosta Castro, Wendy Elizabeth; Cabrera Anda, Santiago Paúl
    This project was born because in the company PRODEGEL S.A. It is necessary to obtain the efficiency of a tunnel-type gelatin dryer since at the moment it presents problems of humidity in the product, presenting on some occasions of the day a humidity greater than that required and on others a lower percentage of humidity. The experimental method was used and the parameters with which the dryer worked were collected, where the humidity value was obtained at 10.3 percent at the exit of the equipment, this corresponding to days in which the dryer worked with an approximate load of 12 kg/min in wet product, according to the data collected it is estimated that the equipment removes 57.2 percent of moisture from the gelatin noodle, that is to say that more than half of the input product was water, obtaining a flow of gelatin of 5.14 kg/min of dry product, the dryer band worked with a speed of 9.5 cm/min, using a total of 3 hours and 32 minutes to leave the noodle to be crushed. As a result, a yield of the noodle drying process corresponding to 56.31 percent was obtained. When analyzing the gelatin noodle according to the quality department, the noodle should have a humidity percentage of 11 percent at the exit of the dryer, and this percentage was obtained by raising the speed of the belt from 9.5 cm/min to 11 .5 cm/min, obtaining satisfactory results.

    Análisis térmico para el proceso de secado de fideo tipo Regin en la empresa Industrias Catedral S.A, para determinar su eficiencia
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2022-09) Goyes Guerrero, David Nicolás; Cabrera Anda, Santiago Paúl
    The experimental work begins due to the need to have an updated energy study regarding the evaluation of thermal efficiency levels in the noodle drying process of tunnel 1 in the company Industrias Catedral S.A; based on the need to quantify the heat used in a typical drying chamber, as well as the most representative energy losses generated in the production of noodles. In the experimental process of calculating the thermal efficiency, it began with the identification of the thermophysical parameters of the raw material, as well as the evaluation of the standard noodle production. The data collection and measurements of normal operating temperatures of the radiator, temperature in the trays, air speed at the outlet of the fans, speed in air outlets, heat used for the drying of noodles, fundamental factors that intervene in the analysis of heat transfer and utilization within a static drying chamber of type trays. As a result, the supplied heat was analyzed in a type chamber, for region noodles, the regin noodles take advantage of 4,067

    Análisis del proceso de secado de aserrín de madera de eucalipto con lámparas infrarrojas para reducir el grado de humedad
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2021-04) Sailema Sisalema, Welington Paúl; Cabrera Anda, Santiago Paúl
    In this project, prior to carrying out the drying process, the necessary fundamentals for compacting the sawdust and drying it were investigated. Identifying the variables such as: the initial humidity, the final humidity, the heat necessary to dry the sawdust, the time and the efficient power of the incandescent lamps. For the study, two types of specimens of different configuration were manufactured, a flat plate and a cylindrical one. For the compaction of the biomass, the homogenization with binder was carried out, in this case white glue to obtain an adequate compaction, when obtaining the specimens it was verified that they all have the same weight 1.88 gr for the flat plate specimen and 1.30 gr For the cylindrical specimen, the initial humidity was 51.60 percent and 30 percent respectively, after drying, it was possible to remove the existing moisture in the specimens, obtaining weights of 0.91 gr for the two configurations, with times of 18 minutes for the flat plate specimen and 24 minutes for the cylindrical specimen. The heat fluxes necessary to dry the specimens were 3529.195 Joule for the flat plate specimen and 2023.399 Joule for the cylindrical specimen and the required power was 3,268Watt and 1,405Watt respectively. Finally, the temperature distribution analysis was carried out by means of a CFD analysis, which shows that after 9 of the prototype of the dryer is in operation, the desired temperature of 65 degrees Celsius is obtained.

    Análisis térmico para el proceso de secado de madera laminada de hasta 5 mm de espesor en la empresa Arboriente S.A. en la ciudad de Puyo, para determinar su eficiencia
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánica, 2017-09) Hernández Cuenca, Walter Wladimir; Cabrera Anda, Santiago Paúl
    Once the operating conditions were stabilized, the necessary data and measurements were made, namely temperature, main components of the continuous dryer chambers, average ambient temperature; the components and the structure of the dryer were modeled in order to obtain the mass of each of them, fundamental parameters for the calculation of heat losses. Once the thermodynamic and physical properties of the components were determined, the calculation of heat losses by conduction, convection and radiation was developed. Depending on the mass flow of steam, it was obtained that the heat supplied to the dryer has a magnitude of 474.46 KW. The efficiency of the process was obtained as the quotient between the heat consumed by the processed wood 257.82 KW and the heat flow supplied by the cauldron 474.46 KW, obtaining a value of 54.34%.
