Tray Drier 280 g ok mango slices are dried in a tray dryer where the top surface is exposed to air flow with an area of 0,15m at a velocity of 1,8 mls. The deuing air (Pair = 4,057 kg/mp) has an inlet dry bullo temperature 60C and 5% RH and leaves at 40% RH. If the drying occurs in constant rate period and 0,08 kg water / kg dry matter, the equilibrium moisture content (Xe) is a) Calculate the rate of drying for constant rate period. b) Calculate the drying time necessary to dry manga stices from on initial moisture content of 87,5%. (wet basis) to a final moisture content of 55,2% ( wet basis). e) Find the dry bulb temperature of outlet drying air. d) Calculate the total amount of drying air used in the dryer at inlet conditions.
