In drying casein, the dryer is found to consume 4m3/h of natural gas with a calorificvalue of 800kJ/mole. If the throughput of the dryer is 60kg of wet casein per hour, drying it from 55%moisture to 10% moisture, estimate the overall thermal efficiency of the dryer taking into account the latent heat of evaporation only. The latent heat of vaporization of water is 2257 Kj/Kg. (A) Approximate thermal efficiency of dryer is 48% (B) Approximate thermal efficiency of dryer is 36% (C) Amount of water to be evaporated is 35 kg/hr (D) Amount of water to be evaporates is 30 kg/hr In drying casein, the dryer is found to consume 4m3/h of natural gas with a calorificvalue of 800kJ/mole.
