Air at 35 'C and RH 45% is flown into the heating coil so that the temperature of the dry balls is 85 "C. Then air is used for drying by passing it to the granular pet food pile. The air exiting the pile has a dry ball temperature of 65" C. This air is then reheated to 80 ° C and flown into the pile of other pet food. The air coming out of the second dryer is in a saturated state. Describe the process that takes place from ambient air to saturated air from dryer 2 in a psychrometric diagram: Determine the amount of water removed in the first and second dryers per kq of dry air. a. first dryer = (kg water / kg air). b. second dryer = (kg water / kg air)
