The direct drum dryer is a high temperature drying technology.
The drum dryer is a classic drying technology, and it has a high energy efficiency. The exhaust gases coming from a furnace, a NG burner or other processes enter directly the drum, and together with the wet product passes through it. At the drum's outlet a gas treatment system is required to separate the product from the gas stream and avoid particle emission to the atmosphere, as well as VOC's.
