This paper presents a technical feasibility study for drying the biomass of green bananas at a pilot plant spray dryer with rotary atomizer. The biomass of the green banana is a component that can be used industrially in a wide variety of foods, with functional properties, especially the presence of resistant starch. The variables selected in the experimental procedure were the biomass concentration of green banana, feed flow rate and rotation of the atomizer. Responses were obtained as the mass and relative humidity of the dried product. Three levels were used in selected variables, which corresponded to the completion of 27 experiments. In experiments in which they obtained the lowest values of relative humidity, the amounts of mass were also the lowest, while in experiments where they met the higher amounts of the levels of relative humidity ranged from the highest. Considering the industrial application, whose purpose is the low humidity and increased production of the product, test 22 was the most appropriate, and found 11% moisture and 4.33 g in mass.
