Prevents microbial growth and spoilage.
Lowers weight and volume of materials.
Water that exerts vapor pressure like pure water.
Drying removes small amounts of water from solids.
Moisture level in balance with surrounding air.
Solid absorbs moisture until equilibrium is reached.
Moisture above equilibrium, removable by drying.
Moisture held within a substance, not easily removable.
Batch dries for a set time; continuous adds and removes material constantly.
Gas velocity, air temperature, and humidity.
Moisture level where constant drying rate ends.
Higher temperatures increase drying rates.
Shows how drying rate changes with moisture content.
Thicker solids decrease the rate of drying.
Diffusion involves concentration differences; capillary involves pore networks.
Drying rate decreases as free moisture reduces.
To maintain a steady flow of material and air for drying.
Through diffusion due to concentration differences.
Higher humidity reduces the drying rate.
Longer drying times are needed for higher initial moisture.
