To dry cereals, 10,000 m3/h of air is used at 15 C and 586 mmHg and it is compressed to 925mmHg and then it is dried to 191 C and 850 mmHg. The dryer contains 30,000 kg/h of cereals that enter 70% humidity. The generated vapors come out at 110 C and 800mmHg which are then cooled to 38 C, condensing part of the water. The partial pressure of the water vapor in the air inlet stream is 10mmHg and the outflow is 175mmHg. Determine: All streams assuming a dry solid molecular weight of 50,000. Determine the relative humidity at points 1, 2, 3, 4, and determine the humidity of the outgoing dryer cereal. 15C P-586 2:0 = 10 G=10000 My - 30000 2-0.70 6 P-925 4 - 191 Py = 850 Figura 6.23 4 = 100 C P = 800 0 - 175 mm Hg
