The directly heated rotary dryer operates on the principle of lifting and showering the product through a hot gas stream moving. The efficiency of the dryer is largely dependant on the differential between the inlet and exhaust gas temperatures, although the heat transfer rate is also influenced by the relationship between the design of flights and the speed of rotation. However, irrespective ...
