variables of drying on the drying-time curve should be determined in order that an optimal design can be developed. 2. The drying-rate curve, Fig. 2, is drived from the drying-time curve by plotting slopes of the latter curve against the corresponding moisture content. The distinctive shape of this plot, shown in Fig. 2, illustrates the ...
— 3.3 Desiccant calculation . Now we arrive at the crucial point of this calculation, and we will need the help of simulation software to determine the desiccant wheel exit conditions of the air. By knowing this point we can continue simulating the remaining processes: air mix, heat gains from fans, and sensible cooling.
— In direct heat rotary dryers, a hot gas flowing through the dryer provides the heat required for the vaporization of the water. To promote gas–solid contact, most direct heat dryers have flights, placed parallel along the length of the shell, which lift solids and make them rain across the section of the dryer Fig. 1).
1) Thermal inefficiencies in the dryer: exhaust heat content in convective dryers, sensible heating of solids, heat losses from dryer body. 2) Thermal inefficiencies in the utility (heat supply) system: steam generation efficiency, steam leaks and mains losses. 3) Additional energy demands: power for solids transport, vacuum pumps and air fans.
