Diseño y simulación de una Planta Termosolar Pasteurizadora para la planta de ordeño de la Escuela Superior Politécnica de Chimborazo.

Abstract

The objective was the design and simulation of a thermo solar pasteurizing plant for the milking plant of the Superior Polytechnic School of Chimborazo, located in the Licto parish of the Riobamba canton, the design was made by mass and energy balance for selection of equipment for capturing solar radiation by parabolic cylindrical collectors and steam generation both to raise temperature for pasteurization and to perform solar cooling by absorption technique, the engineering calculations aided in the selection and sizing of each of the devices involved in this process, finally the verification and validation of these calculations were done in a SolidWorks computer software and drawn in third dimension according to technical sheets delivered by thepossible suppliers, where thermal oil temperature results of 180 °C were obtained at the outlet of the manifolds and the same heat flow delivered to a countercurrent heat exchanger sized with a transfer area of 0,35 m2 to change the phase liquid water To saturated steam which, will drive a machine of absorption double effect of 5 bar of pressure and at the same time deliver this steam to a plate exchanger to pasteurize 700L/d of whole milk from the milking plant of the Tunshi experimental station. Concluding that this pasteurizing thermo solar plant helps the environment since it does not generate pollutant emissions to the atmosphere, water, soil and also through simulation could be observed the operation of this plant in real time. It is recommended to perform a long, medium, and short-term maintenance matrix.
