“…The schematic of the experimental setup and the details of the dryer geometry have been reported in our earlier work. [4,5] The effective length of the screw for drying purpose was 2.34 m. The screw speed can be varied between 10.8 and 28 rpm. The required flow rate of solids can be set by adjusting the opening of a feed inlet.…”

“…The thermal efficiency can be still increased by maintaining proper operating conditions and understanding the relative contribution of heat transfer by conduction and convective modes. Waje et al [4,5] have provided a logical stepwise procedure for screw conveyor dryer design based on the heat and mass transfer calculations. Recently, Waje et al [6] have studied the residence time distribution and the flow patterns in SCD using a pulse tracer technique and found that the flow predominantly lies between the ideal plug flow and the mixed flow regime.…”

“…9 Waje et al conducted a series of experiments and published several papers about screw conveyor dryer. [10][11][12][13] They investigated residence time distribution (RTD) and mean residence time (MRT) in screw dryer conveyor and found out that with the increasing screw speed, degree of mixing is increased but MRT is decreased. The flow in a screw conveyor dryer approaches plug flow as the feed rate is increased, whereas an increase in the screw speed results in a mixed flow.…”

“…By virtue of the needs of the project and required characteristics, it was decided to design, prototype, and test a drier auger, denominated in the literature SCD (Screw Conveyor Drier), where the heat transfer fluid exchanges heat indirectly with the material to be dried [3], [4]. Figure 2 shows a diagram of a drier auger where heat exchange is direct or indirect.…”

“…A flow of gas inside the drier, with the sole purpose of transporting the evaporated moisture away from the material, is an important factor. The flow of gas can enter and exit from the drier extremes and be cocurrent or countercurrent with the motion of the material to be dried [5], [6].…”
