Diseño e implementación de un agitador semiautomático de doble hélice para una marmita de mosto de mortiño de 1000 litros de capacidad, para la parroquia de Quinticusig, provincia de Cotopaxi

Abstract

The present project for the design and implementation of a stirring system was carried out in the community company "Perla Andina" in the Quinticusig community, Sigchos canton, which has a thousand-liter kettle in charge of fermenting wine from mortiño, where there is a different degree of fermentation between the upper and lower part of the container, having the risk that the mixture does not meet the ideal characteristics. For the project to fulfill its purpose, it had to go through a process divided into four chapters. In the first chapter, based on an oral and bibliographic investigation, the situation of the community company “Perla Andina” was established; the history and the process of making mortiño wine, focusing on its fermentation; Similarly, the elements that make up a stirring system were established, considering the construction material, control systems and welding. Next, in the second chapter, the most viable agitator was selected among three alternatives, taking into consideration the theory shown in chapter one and the fundamental parameters for its design and implementation. Once the type of agitator was selected, in the third chapter, the mechanical elements that make up the agitation system were designed, which were: impellers, shaft, bushing, blocks, flanges, frame and keys, establishing adequate safety factors; Likewise, the bearings, welding and the elements of the power system were selected, such as: motor and gearbox. After the design, in the fourth chapter, an economic study was carried out, where the total costs of the project were determined, establishing the profitability, viability and recovery time of the investment. Finally, a vertical stirrer inclined at 18 ° was implemented with two paddle-type impellers with an inclination of 20 °, the same one that helped to move the mixture towards the top, reducing the fermentation time and increasing the production capacity in a 30% for each batch. This system is driven by a 0.5HP single-phase motor, which is controlled by a semi-automatic ON-OFF system at 17 rpm.
