Indirect rotary dryers IDRECO S.r.l.

Indirect rotary dryers. Indirect rotary dryers differ from convective-direct 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 combustion chamber.
