Rotary drum in a sugar refinery, is also called sugar rotary dryer.



Working Priciple:   
A countercurrent drying drum offers perfect conditions for effective drying of the moist sugar crystals after centrifugation. The drum dryer combines the mechanical treatment of the crystal surface and slow drying conditions in an ideal manner. To control the drying effect in the drum dryer, heated air can additionally be fed into the dryer through a central pipe.

With this type of dryer, there is a perfect balance between energy input and water evaporation rate.

Benefits:

• Rotatioal drum movement exposes the surface of the sugar crystals to mechanical action

• Heat inside the sugar crystals is utilized for efficient drying

• Large drum volume helps produce uniform product flow rates

• Sugar lumps or short periods of elevated sugar moisture are tolerated without any problems
 

Application:
Beet and cane sugar factories, and sugar refineries for the drying of refined sugar, white sugar, and/or VHP and VLC sugar.
