Diseño y simulación de un prototipo semiautomático para sellado de queso al vacío para la Unidad de Innovación de Lácteos de la Universidad Politécnica Salesiana ubicada en el cantón Cayambe provincia de Pichincha

Abstract

This degree work details the design and simulation of a semi-automatic prototype for vacuum cheese sealing for the dairy innovation unit, located in the Cayambe canton, province of Pichincha, belonging to the Salesiana Polytechnic University. In chapter 1, research on cheese production in the Cayambe canton is presented, where data related to the amount of milk processed, the variety of cheeses in types and sizes, as well as the production practices used in the canton are presented. This research provides data to improve cheese quality and production. In addition, the initial parameters for the design of the vacuum packaging machine are established. After the investigation, chapter 2 proposes three alternatives for the implementation of the vacuum packaging machine. These alternatives are evaluated considering factors such as production capacity, costs and technical feasibility. The choice of the alternative was based on a higher score quantitative analysis. This guarantees that the machine best adapts to the needs of the industry in Cayambe canton and is effectively integrated into its production process. In chapter 3, the development of the design of the vacuum packaging machine is carried out, based on the parameters of the selected alternative. This design is prepared using computer-aided design (CAD) programs to guarantee the required safety factor. Calculations are presented to justify design decisions and ensure machine safety. Additionally, electrical and pneumatic diagrams for the vacuum and heat sealing process are included. Chapter 4 presents the simulations of the designed vacuum machine, in critical sections such as the structure, link and hinge, to guarantee its robustness and durability. Additionally, in this chapter a cost analysis is carried out to evaluate the economic viability of the project, calculating the NPV and IRR to determine if the future implementation of the packaging machine is profitable. Finally, the conclusions and recommendations obtained from the development of this degree work are presented.
