✦ Synopsis

A model of surface renewal is developed based upon the concept that praticles can move randomly between inactive and active domains within a contacting device. This type of model has application to particulate systems where reactions are occurring on the particle surface. Application is made of these concepts to fluid bed coating of particfes. Fluid bed coating of particles is important as a process to enable time release capsules where time release behaviour is associated with the coating weight distribution.
