Modelación del secado neumático vortiginoso del bagazo de la caña de azúcar//Modulation of sugar cane bagasse pneumatic drying in a vortex
Abstract
Tomando en consideración los estudios realizados sobre la modelación del movimiento vortiginoso de partículas de bagazo, se realizó el estudio del secado neumático de esta importante biomasa teniendo en cuenta la transferencia de calor y de masa. Se modeló el proceso de secado a través de las ecuaciones
fundamentales que describen la cinética del mismo y se compararon los resultados obtenidos con resultados reportados en la literatura especializada sobre mediciones de la variación del contenido de humedad en otros tipos de secadores neumáticos de bagazo para iguales condiciones de operación. Esta modelación permitió realizar simulaciones de este proceso las cuales arrojaron resultados aceptables en cuanto a los valores de disminución del contenido de humedad del bagazo lo que permitirá continuar profundizando en el desarrollo de próximos estudios sobre el tema ya que se evidencia que por esta vía es posible disminuir las dimensiones de los secadores de bagazo.
Palabras claves: secado neumático vortiginoso, secado de bagazo, modelación matemática.

Abstract
Taking in account the studies carried out about the vortex movement of bagasse particles, the study of pneumatic drying of this important biomass was carried out considering the heat and mass transfer. The drying process was modeled through the fundamentals equations which describe the kinetic of it and the
obtained results were compared with results reported in the specialized literature on drying measurements in others kinds of bagasse pneumatics dryers under the same conditions of operation. This modulation permitted to made simulations of this process which produced acceptable results about the decrease humidity values of bagasse and it will permit to continue in the development of next studies about this topic because it is evident that it is possible to reduce bagasse dryer dimensions.
Key words: pneumatic vortex drying, bagasse drying, mathematical modeling.
