ABSTRACT
Orange juice is consumed worldwide, with Brazil and the United States being the largest producers. The waste pulp corresponds to approximately 50% of the weight of the fruit. As a result, large amounts of solid wastes are generated by the citrus industry, making its disposal potentially hazardous to the environment. This work aimed at the modeling of orange waste drying in a conical spouted bed, for temperatures of 70, 80, and 90°C, and inlet flow rate 70% above minimum spouting velocity. A two-phase perfectly stirred tank reactor model was derived and used in a cascade configuration with time-varying parameter update.
