The movement of particles in rotating drums depends on the flights and shell design, as well as on the operating conditions. Thus, rotary dryers represent one of the greatest challenges in theoretical modelling of dryers (Sherrit et al ...

    Abstract This paper deals with the problem of fitting a set of data collected on a rotary sugar dryer, by means of a first-principles mathematical model. Owing to the highly constrained structure of the model, it was discovered that the sugar dryer is characterised by two different working conditions: the “standard-mode” (characterised by a non-zero sugar moisture content), and the ...
