✦ Synopsis
When dlffuslon mslde the sohd particles which are dried m a fluldlsed bed can not be neglected this Internal ddTuslon can be accounted for by two mechanisms (a) the long term response which describes the gradual build up of a concentrahon profile inside the solid particles as function of the total drymg time, and (b) the short term response which describes the generation of a thm concentration boundary layer mslde the particles durmg the passage of these particles through the cloud of a nsmg bubble Both mechamsms can be analyzed separately and are mcluded m a final model which can be conceived as a further development of the model presented m Part I
