Chapter 6 DRYING - Universiti Teknologi Malaysia

Q7 A wet solid is to be dried in a tray dryer under steady-state conditions from a free moisture content of X 1 = 0.40 kg H 2O/kg dry solid to X 2 = 0.02 kg H 2O/kg dry solid. The dry solid weight is 99.8 kg dry solid and the top surface area for drying is 4.645 m2. The drying-rate curve can be represented by figure shown in slide #19.

PROBLEM 10 - bkhoshandam.tripod.com

The sand passes through each stage and hence the sand in the underflow from stage 1 = 0.4 kg/s, which, assuming constant underflow, is associated with (0.4/2) = 0.2 kg/s water. Similarly, 0.2 kg/s water enters stage 1 in the underflow and 0.4 kg/s enters in the overflow. Making a water balance around stage 1, the water in the overflow ...

Study on Sand Particles Drying in a Fluidized Bed Dryer ...

Here the wet sand particles are fed to the dryer through a conveyor. The hot air from the bottom of the dryer passes through the nozzles embedded in the dryer bed and rises up. This upwind do not allow the wet sand particles to settle down. Instead, the sand particles are in a fluidized state inside the dryer.
