Viabilidad técnica-económica de un sistema de energía solar térmica para un proceso de pasteurización de leche en la parroquia san juan de la Provincia de Chimborazo

Abstract

The objective of this study was to analyze the technical-economic feasibility of a solar thermal energy system for the milk pasteurization process in the San Juan parish of the Chimborazo province. The research was experimental, with a mixed approach and an exploratory, descriptive and explanatory level of depth. First, the collection of information from the Scopus, RRAAE and parish PDOT digital repositories was carried out to identify the actors and factors involved in the milk production chain; then, the survey was applied to 10 representatives of the dairy microindustries of the parish to know their perception in the technical, economic and environmental aspects, the data is analyzed using descriptive frequency statistics; through Microsoft Forms and Atlas T.I., the instrument was validated using the expert judgment validation technique. Subsequently, a proposal for a solar thermal pasteurization system for 300 L/day was made, and the associative strategy for introducing the system was proposed. In addition, historical facts and environmental factors in the intervention chain were identified, and three actors involved were evidenced: suppliers, dairy micro-industries and distributors. The representatives of the microenterprises need to learn about solar thermal pasteurization systems. However, they want to start an energy transition to save energy costs. From the technical-economic point of view, the collector has a yield of 58.01% and an investment of $12,900.00. Finally, it was determined that the application of an associative strategy, focused on the cooperation and joint participation of microentrepreneurs, will allow the implementation of the project. Governments, academic institutions, etc., must focus on developing associative strategies since they benefit local progress.
