160 kg of wet solid is to be dried from an initial moisture content of 25% to a final value of 6%. Drying test shows that the rate of drying is constant at 3 x 10-4 kg H20/ mn.s in the region 0.2 – 0.44 kg H20/ kg solid. The drying rate falls linearly in the range 0.01 - 0.2 kg H20/ kg solid. If the equilibrium moisture content is 0.01 kg H20/ kg solid, calculate the time of drying. The drying surface is 1 m? / 30 kg dry weight.

160 kg of wet solid is to be dried from an initial moisture content of 25% to a final value of 6%. Drying test shows that the rate of drying is constant at 3 x 10-4 kg H2O/ m².s in the region 0.2 – 0.44 kg H2O/ kg solid. The drying rate falls linearly in the range 0.01 - 0.2 kg H20/ kg solid. If the equilibrium moisture content is 0.01 kg H2O/ kg solid, calculate the time of drying. The drying surface is 1 m? / 30 kg dry weight.
