(E (4,9)) Studies on the spraying process of concentrated sugar solutions for coating purposes A pilot plant scale system was used to investigate the spraying or atomisation process for spray coating pharmaceutical products, as illustrated in Figure El. In this study, maltodextrin solution was chosen as a model of the liquid feed for the spraying process. The diameter of the spray droplets of maltodextrin solutions were measured using an imagine system. The physical properties of the maltodextrin solutions and the experimental results of the atomisation process of the maltodextrin solutions are presented in Table El- Figure EI: A pilot plant scale atomiser for maltodextrin solutions. Table El: The physical properties, the atomisation process conditions, and the droplet diameter of the of the maltodextrin solutions.
