Abstract

A continuous vertical fluidized-bed dryer operates through a series of downcomers that transfer solids from an

upper low-pressure stage to a lower high-pressure one. This work informs on the results testing a system of plastic

particles of 0.009m diameter, 1090 kg/m3 of density, and 0.94 of sphericity, under a counter-current airflow in two

pressure stages. Each stage has 0.25m internal diameter Perspex tube and a height of 0.6m. Perspex tubes having

0.032 and 0.057m, internal diameter, fitted with a conic valve at the end of each one were used as downcomers in

the experimental system. By using a 23 experimental factorial design, it was observed that the fact with the highest

influence on the results was the length of bed/ diameter of bed (L/D). It was also found that the downcomer with

the widest diameter showed the best behavior when operating with an L/D = 0.5 and an L/D =1, and gave a lower

dragging risk as compared to the narrowest diameter.
