Diseño y simulación de un prototipo pasteurizador de leche con capacidad de 50 litros para la estación de investigación de la Universidad Politécnica Salesiana, ubicada en el cantón Cayambe provincia de Pichincha

Abstract

In the current document, the design and simulation of a milk pasteurizer prototype is conducted with the objective of processing said raw material for safe consumption, free of pathogens that generally exist in raw milk that is produced in the cattle fields of the Ecuadorian mountain range. This schema was implemented at the Research Center of the Salesian Polytechnic University in the Cayambe canton, Pichincha province, which contributes to improving the grade of the milk that is consumed. In chapter I, a theoretical framework is carried out considering some pasteurization methods, for which the L.T.L.T. process was chosen. (low temperature, short time), which consists of heating the fluid to an average temperature of 62 - 65 °C in a time of 30 minutes inside a stainless steel kettle, later giving a rapid cooling in the same container until a temperature of 15 °C and with the help of a stirrer to maintain a homogenized temperature throughout the container, with which the milk can be used for packaging or processing for other dairy products. In chapter II, different choice for the design of the pasteurizer prototype is dissect, considering that it will be of limited production, since the purpose of the equipment is to pasteurize milk, to carry out investigations of the conduct of the cooling speed, as well as the times of pasteurized, to determine hygiene and quality of milk. In chapter III the design of the equipment for the volumetric ability of 50 liters is developed, complying with the requirements requested by the C.I.S. (Research Center of the Salesian Polytechnic University) and the INEN (Ecuadorian Institute for Standardization) regulations in force for the processing of raw milk in Ecuador, validating the design through a simulation of static loads in ANSYS where information can be obtained for the construction of the prototype. Finally, chapter IV refers to the financial analysis to validate that the prototype is profitable and complies with its operation.
