Question

Potato flakes (moisture content = 75% wet basis) are being dried in a concurrent flow drier. The moisture content of the air entering the drier is 0.08 kg of water per 1 kg dry air. The moisture content of air leaving the drier is 0.18kg water per 1kg of dry air. The airflow rate in the drier is 100kg dry air per hour. As shown in the figure below, 50kg of wet potato flakes enter the drier per hour. At steady state, what is the mass of “dried potatoes”?
