To Improve Flow Properties of Starch Powder by Adapting Spray Drying Process

Pharmacy

Powder characteristics of materials are important in a variety of industrial operations. In this study, we investigate how to improve the flow characteristics of starch powder by using a modified spray drying procedure. The study includes a thorough examination of the starch powder's moisture content, angle of repose, bulk density, Carr's index, and Hausner's ratio both before and after the spray drying method was modified. Samples of starch powder were first evaluated for their baseline flow characteristics. Then, with certain adjustments, the spray drying method was used to maximize the starch powder's flow characteristics. The feed rate, atomization pressure, and inlet temperature were the modified spray drying parameters. The flow characteristics of the spray-dried starch powder samples were then examined using common testing techniques. The flow characteristics of the starch powder were improved, according to the results of the spray drying treatment. The powder flowability was improved as a result of the significant reduction in moisture content. An improvement in particle packing and a decrease in interparticle friction were indicated by the angle of repose. Additionally, there was an increase in bulk density, which indicates improved powder compaction. Both Hausner's ratio and Carr's index showed a significant drop, suggesting less cohesiveness and better powder flow. Overall, this study's results demonstrate how well the modified spray drying method works to enhance the flow characteristics of starch powder. The powder's enhanced flow characteristics create new opportunities for its application in a number of sectors, including food processing, cosmetics, and pharmaceuticals, where a uniform and smooth powder flow is critical. To investigate the real-world applications of this improved flowability in various manufacturing processes, more application-specific research is advised.
