Transportar y secar materiales son dos actividades usuales en diferentes procesos productivos y los tornillos transportadores sirven para realizar estas dos actividades simultáneamente. Las condiciones de operación de un tornillo transportador son importantes porque influyen directamente en características finales como son el grado de secado del producto y la eficiencia térmica del proceso. En este artículo se emplearon los modelos GAMLSS para estudiar la influencia de tres variables operacionales, velocidad rotacional del tornillo, temperatura y flujo de alimentación, sobre el grado de secado del acetato de calcio dihidratado al ser transportado y secado en un tornillo. En este artículo se encontró que el modelo de regresión beta permite explicar el grado de secado mejor que otros modelos de regresión como el normal, exponencial, gamma, Weibull y logit-normal. Adicionalmente se encontró que, la operación del tornillo a una temperatura de 45°C, velocidad rotacional de 3 rpm y una velocidad de flujo de 6 L/min permiten obtener el máximo grado de secado 35,46%.
