Diseño estructural de un secador continuo y herramienta para volteo de cafés especiales

This paper comprise the structural design of a dryer with stirring system to obtain specialty coffee of highest quality, which includes: (i) Design analysis to determine the shape of a advantageous stirring device, (ii) deduction of an equation to calculate the required torque for turning tool and (iii) a computational fluid dynamics (CFD) analysis of the dryer for thermal conditions, in order to validate the design variables. It was possible to propose a hybrid system with an innovation factor that guarantees a dried coffee with controlled conditions and in a shorter time, which introduces the farmer in a dynamic of precision in his objective of maintaining the permitted percentages of humidity, guaranteeing a quality coffee in a cup.
