FAT (Fault tree analysis) of drying processing was performed to investigate the causes for faults in equipments management. The causes were deductively identified as the events causing every possible hazard by constructing a fault tree. The fault tree was constructed in a hierarchical structure with a single top event fault, four intermediate event faults, and eight basic event faults connected by a Boolean AND gate, or an OR gate. Qualitative analysis of the fault tree yielded minimal cut sets, structural importance, and common cause vulnerability. Quantitative analysis of the fault tree yielded simulation of final top event fault, cut set importance, item importance, and sensitivity. Basically, these factors were a measure to represent the priority order of the basic events causing the top event. The priority order of these basic events was consistent between qualitative and quantitative analysis. Therefore, the FTA, with qualitative and quantitative analysis, was a good alternative approach to fault analysis in spray dryer, and it also could be further used to the analysis of critical control points..
