A half sectional spout-fluid bed column with draft tube was used for the cleaning and drying of guava seeds in one single operation. The process took place on a batch basis with a constant spouting velocity of 1.5 U-ms and an additional annular air flow rate equivalent to 0.5 and 0.7 U-mf. A regression model based on the spouting air temperature T-s, the annular inlet air temperature T-a, and the additional annular air flow rate xU(mf) was obtained to calculate the drying time. An additional cleaning step was necessary to increase the separation efficiency of the dried pulp from about 70% obtained during the drying process to 84%.
