Drum flaker /Drum Drier

2) Short drying time: The drying process only takes 10-15 seconds. So drum dryer can be used for drying heat sensitive material. 3) Uniform drying: Heat transfer direction and coefficient all over the drum surface are the same. And wet material can be evenly spread over the drum surface. Wet material can be uniformly dried.

Transverse flow at the flight surface in flighted rotary drum

The angle made by the surface of the material in the rotary drum with the horizontal is called the dynamic angle of repose (Θ). The bed remains stable until this angle approaches the upper angle of repose or the maximum angle of stability [18], [19] and the avalanches begin when the dynamic angle exceeds this angle. The frequency of these ...

The design of flights in rotary dryers

Baker [9] also explained how to estimate the optimum number of flights in a rotary dryer to maximize the drum holdup and thus make the most effective use of the dryer volume. Kelly [10] extended his theory to the prediction of the ideal flight geometry that would provide the equal horizontal distribution (EHD) of solids.
