OPTIMIZACION DE CONTROL DE UN SECADOR ROTATORIO PARA PRODUCTOS AGROINDUSTRIALES (CONTROL OPTIMIZATION OF A ROTARY DRYER FOR AGRO-INDUSTRIAL PRODUCTS)
Resumen
Este proyecto de tesis tiene como objetivo la optimización de control de un secador rotatorio de productos agroindustriales. El diseño del control integra instrumentación en un secador rotatorio, diseño de sistema de supervisión través del software LabVIEW V15.0, adquisición de datos que se realiza con una tarjeta NI USB-6009. La interfaz de operación permite controlar el grado de temperatura de aire del secador con técnicas de control P, PI, se programan dos modalidades de operación, offline y online, el modo online muestra el comportamiento del proceso y cinéticas de secado de cascara de naranja del prototipo experimental. El modo offline realiza una predicción de tiempo de secado, porcentaje de humedad final y peso, esto aplicando técnicas de PAGE, WEIBULL Y GAB, modelos ampliamente utilizados y comprobados en el secado de materiales orgánicos para la generación de cinéticas de secado. La discusión se centra en la aplicación de la optimización de un secador de productos agroindustriales a través de la instrumentación y aplicación de técnicas de control para mejorar el consumo energético, bases que servirán de análisis para la mejora de secadores rotatorios de alimentos agroindustriales en el futuro.
Palabras Clave: Cinéticas, controladores, instrumentación, modelos y secado.
Abstract
This thesis project aims to optimize the control of a rotary dryer for agro-industrial products. The control design integrates instrumentation in a rotary dryer, supervision system design through LabVIEW V15.0 software, data acquisition performed with a NI USB-6009 card. The operating interface allows controlling the degree of air temperature of the dryer with P, PI control techniques, two modes of operation are programmed, offline and online, the online mode shows the behavior of the process and the kinetics of the orange peel drying process. experimental prototype. The offline mode makes a prediction of drying time, percentage of final moisture and weight, this applying PAGE, WEIBULL and GAB techniques, widely used and proven models in the drying of organic materials for the generation of drying kinetics. The discussion focuses on the application of the optimization of a dryer for agro-industrial products through the instrumentation and application of control techniques to improve energy consumption, bases that will serve as analysis for the improvement of rotary dryers for agro-industrial food in the future.
Keywords: Kinetics, controllers, instrumentation, models and drying.
