• Determine the H2O uptake for each of the materials.

• Determine the optimum drying conditions for each material.

• Do not exceed 80 deg C in the batch dryer.

• Scale up the process to 12 T/day on a continuous belt dryer that is 4 ft wide and 50 ft. long for the best candidate.

• Report your findings to management with your recommendations.

• Temperature control should be included.

A desiccant is a material that readily soaks up water vapor from surrounding air. The desiccant will continue to adsorb moisture until it becomes saturated. These desiccants or adsorbents are generally classified as amorphous or structured, and hydrophobic or hydrophilic. Many different substances exist which are capable of adsorbing, but few are of industrial significanc

In order to analyze this procedure, the theory of solid drying must be understood. Solid drying involves two underlying processes:

4. Re-weight wetted desiccants on loading tray and find total weight
