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. 15°C P-586 2:0 = 10 G=10000 My - 30000 2-0.70 6 P-925 4₂ - 191 Py = 850 Figura 6.23 4 = 100 °C P₁ = 800 0 - 175 mm Hg 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.
