A fluidized-bed dryer is being used to dry diced carrots. The product enters the dryer with 60% moisture content (wet basis) at 25°C. The air used for drying enters the dryer at 120°C after being heated from ambient air with 60% RH at 28°C. Estimate the production rate when air is entering the dryer at 700 kg dry air/h and product leaving the dryer is at 7% moisture content (wet basis). Assume product leaves the dryer at the wet bulb temperature of air and the specific heat of product solid is 2.0 kJ/(kg °C). Air leaves the dryer 10°C above the product temperature. Specific heat of water = 4.175 kJ/kg K. Assume negligible heat loss from surface of dryer, q=0.
