Question: A batch dryer removes water from a solid at a rate of 30 kg/ hr during the constant rate period. Critical moisture content is 0.25

A batch dryer removes water from a solid at a rate of 30 kg/ hr during the constant rate period. Critical moisture content is 0.25 kg H2O/kg dry solid. The equilibrium moisture content of the material is 0.035 kg H2O/kg dry solid. The dryer is initially charged with 750 kg of total material contains 200 x 1000 g moisture. The final product should contain 0.08 kg H2O/kg dry solid. The falling rate period can be represented by a straight line. The drying area is 5 m2 .
