Sudan Indrect Heat Dryer

Indirect rotary dryers differ from convectivedirect dryers in that heat is transferred to the wet product by conduction and radiation through the cylinder wall or through a series of tubes located circumferentially to the cylinder indirect rotary dryers use as heating medium hot gases coming from a

Indirect dryers employ similar principles of operation to direct dryers however the fundamental difference is that the method of heat transfer is predominantly by conduction as opposed to convection these units are sometimes referred to as contact dryers tube furnace dryers

Dryers andor processors the data presented will show that in all cases the investigators found that by increasing the speed of mixing the heat transfer rate is enhanced except when the agitator speed produces mechanical fluidization andor during the constant rate period of a drying cycle
