Abstract
Optimization of fluidized bed granulating conditions for yield, bulk density, and tapped density of powdered milk was determined using response surface methodology. Yield of powdered milk was greatly affected by feeding rate of water, and bulk density and tapped density could be reduced by decreasing of atomization pressure. The optimum conditions for fluidized bed granulating of powdered milk were predicted with 6$0^{\circ}C$ of inlet air temperature, 16 mL/min of feeding rate, and 2.1 bar of atomization pressure. Also 94% of yield 0.350 g/㎤ of bulk density, and 0.446 g/㎤ of tapped density of powdered milk could be obtained by the optimum granulating conditions.
