For example, in the pharmaceutical industry, it is essential that the same amount of active ingredients to be present in each individual tablet or capsule ( Allen, 1981). This is because a segregated non-uniform mixture can severely degrade the quality of the final product and in many situations, have serious safety implications ( Allen, 1981). In most applications, uniform mixing and blending of the different types of particles is desired. Therefore for such powders, convection is the major mixing mechanism. In free-flowing powders, diffusive and shear mixing give rise to size segregation ( Susana and Santomaso, 2011). There are three mixing mechanisms, namely convective, diffusive and shear ( Charles, 2005). This study focuses on the mixture of coloured particles. In order to increase the homogeneity of the mixture, external forces such as mechanical agitator and gas blower are used ( Howard, 1983). Mixing is defined as a process to combine two or more materials to form one substance or mass. Particle mixing is an important and widely used process in many industries such as chemical, pharmaceutical, food, mining and agriculture ( Kaye, 1997). Of particles mixing process in a fluidized bed. Hence, DIP has high potential to be used for studying performance Gave the same pattern starting at 90 sec which indicate that the particle is Research in an automated particle mixing technique based on image processing.įrom the study, the histogram for colours distribution of red, green and blue Therefore it presents an interesting avenue for The results indicate that particle mixing indeed alters the histogram of images In the image, thus can be used to analyse the quality of the mixing process. Method serves as a proof of concept that particle mixing alters the colour distribution Was implemented to analyse particle mixing in a fluidized bed. Potential in the field of particle mixing and in this paper, colour histogram Yassin ABSTRACTĭigital Image Processing (DIP) techniques have shown great For more information e-mail with your needs.Ĭreative Commons Attribution-NoDerivs 2.5 License.Norazah Abdul Rahman and Ihsan Mohd.
