Abstract
Parameter design using dynamic characteristics is the core of Quality Engineering. In our first report of this study, a spray drying granulation process was studied using a non-dynamic characteristic. In the second report, dynamic characteristic was used. However, there still exist some problems applying the results obtained from the research and development stage to the actual manufacturing process. The final objectives of this study was to apply the spray drying granulation techniques to the manufacturing of our products : herb extracts. It involves the following questions : (1) Will the conclusions be robust against multi-variety products ? (2) Can the conclusions be reproduced in a large scale commercial production as much as ten times larger than the scale of laboratory research ? (3) Can the quality characteristics of these products satisfactorily meet the requirements ? In this report, it was studied (1) if parameter design study could optimize till robustness against various product variety changes, (2) if the conclusions could support the existing technology (such as thermo-fluid analysis using the computer), and (3) if one of the most important quality characteristics, the effect on the moisture content of powder, could be further discussed. The study results supported that such development activities in our study could be used to satisfy the above said objectives.
