A countercurrent tunnel dryer is used to dry apple slices from an initial moisture content of 65% to 5% (wet basis). Hot air enters at 95 ° C with 1% RH, and exits at 52.0 ° C. If the product temperature along the dryer is 20 ° C and the solid specific heat of the product is 2.2 kJ / (kg ° C), determine the rate of hot air required to dry the wet product at a rate of 200 kg / hr. Determine the RH of the dryer exhaust air. a. Drying air rate (ma) = kg / hr. b. RH of dryer exhaust air =%
