The need and desire to use renewable, sustainable, and efficient energy have led to increased research in this field as the long term consequences of not doing so will affect the environment. As an alternative to drying particulate materials using gas and electricity we decided to design, manufacture, and evaluate the performance characteristics of two air collectors for a Linear Fresnel Reflector (LFR) prototype, intended to dry ripe coffee beans to a desired temperature of 50 oC. A steady-state thermal network analysis and computational modeling techniques were conducted to predict the thermal performance of the desired collectors. They were manufactured and assembled along with the optical frame of the prototype in order to carry out the required experiments to test the system. The thermal network analysis and that of the computation modeling for one of the designs agreed with one another. The second design was then analyzed by computational model and showed a better performance than the first collector. The experiments showed that both collectors reached the desired air temperature at the outlet with the second collector outperforming the first design demonstrating that the LFR might be a viable system to dry coffee beans. ; La necesidad y el deseo de utilizar la energía renovable de forma eficiente ha dado lugar a un aumento en su investigación ya que las consecuencias a largo plazo de no hacerlo afectará al medio ambiente. Como alternativa al secado de materiales particulados utilizando la quema de gas y la electricidad decidimos diseñar, fabricar y evaluar las características térmicas de dos colectores de aire para un prototipo de un Reflector Linear de Fresnel (LFR) destinado a secar los granos de café maduros a una temperatura deseada de 50 °C. Se llevó a cabo un análisis de la red térmica en estado estacionario a la vez que se utilizó técnicas de modelado computacional para predecir el comportamiento térmico de los colectores deseados. Estos fueron fabricados y montados junto con el marco óptico del ...
