Abatch 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 h okg dry solid. the equilibrium moisture content of the material is 0.035 kg hzokg dry solid. the drier is initially charged with 750 kg of total material, which contains 2 00 000 g of moisture. the final product should contain 0.08 kg h. olkg dry solid. the falling rate period can be represented by a straight line. the total drying area is 5 m2 2.1. draw a schematic diagram that depicts the process. 2.2. determine the total drying time to produce the product.
