Abstract

This paper presented an investigation to the influence based on the application of air speed and spray pressure in producing granule with good criteria. This research is aimed to obtain the optimal value of air speed and spray pressure. The range of parameter that used in this experiments are from 15 Hz until 45 Hz for air speed while for spray pressure are form 0.2 MPa until 0.5 MPa. Percentage of the concentration that are used in this experiments are 50%. That’s mean the concentration use 100 g of urea and 100 ml of distilled water. Besides that, the temperature that used in this experiments are remained constant which are 60 degree Celsius for drying or dehumidifying process and 42 degree Celsius for agglomeration process. This experiment are run using Fluidized Bed Granulation machine and apply the parameter by using Design Expert software. All the produced granule will be analyze with an acceptable size which are from 2.0 mm until 5.0 mm. After that, granule that have been produced will be run hardness and density test according to the standard that have been assigned. Design Expert software will be run the analysis according to the data that have been recorded. Result from Design Expert software need to run another experiments for validation of the parameter. Finally, this experiments will give an enough information for the optimum parameter to produced the good quality of granule. Finally, the optimum parameters for air speed are 28.30 Hz while 0.50 MPa for spray pressure.
