6 RTD sensors were used in the setup to measure the air temperatures. These were: at the inlet of SAC (outlet of trapezoidal duct), theinlet of drying chamber (or outlet of SAC), four measurements at eachtray inside the chamber, as shown in Fig. 3. A humidity transmitter wasplaced at the inlet of drying chamber to measure the relative humidity(RH) of hot air coming from SAC. A block diagram of all componentsand measuring locations is mentioned in Fig. 3. The components andaccessories of ITSD with specifications are given in
