Spray drying technology: an overview

a) Co-current flow: in a co-current dryer, the spray is directed into the hot air entering the dryer and both pass through the chamber in the same direction. b) Counter-current flow: in this dryer design, the spray and the air are introduced at opposite ends of the dryer, with the atomizer positioned at the top and the air entering at the bottom.

A Study of Efficient Drying Parameters for Bed Dryers

explored. The wheat is dried from a moisture content of 0.22 kilograms of water per kilograms of dry basis to a moisture ratio of 0.05. Energy and exergy efficiencies are utilized as a determining factor for most efficient drying parameters. The results prove that the dryer is most efficient when the dryer runs at 370 Kelvin and 0.3 meters per
