A 24ft diameter bin is filled to a depth of 18ft. with 22% moisture shelled corn. The shelled corn will be dried to a final average moisture content of 14.5% using a low temperature drying system. The ambient air has a dry bulb temperature of 60∘F and a wet bulb temperature of 55∘ F. A fan and heater raises the drying air temperature to 67∘F. The exhaust air coming from the bin is at 100% relative humidity. a. Draw a diagram of the drying process on a sketch of the psychrometric chart, identify the plenum (P) and exhaust air (E) state points. Indicate the humidity ratios for the plenum and exhaust air.
