A spray drier with a 5m diameter and 10m height is used to dry skim milk to a final moisture content


A ramification drier delay a 5m transection and 10m altitude is used to dry graze allay to a conclusive dampness pleased of 5%. The air entering the drier is 120°C, is fierce from ambient air at 25°C and 75% RH, and flows concurrently delay the effect droplets (and particles) through the order. The graze allay is atomized into the hot air at 45°C delay a culmination droplet dimension of 120 micron diameter. The accurebuke dampness pleased for the effect is 30%, and the particle transection is 25 micron at the accurebuke dampness pleased. The equilibrium dampness pleased of the dry graze allay is 3.5% at the exit temperature of 55°C from the drier. The concretion diffusivity for inspire fume delayin the effect particles is and the specific ardor of effect solids is 2.0kJ/ kgK. The fierce air leaves the order at 5°C overhead the effect temperature. The moderebuke dampness pleased of graze allay is 90.5% wet foundation. Determine the effection rebuke for the ramification drier; kg of 5% dampness pleased effect per ace term.
