Product Drying

Desiccant systems can be effectively applied for product drying, regardless of the temperature, whenever there is a need for a low dewpoint. Additionally, they are effective for speeding product drying under conditions where temperature must be limited to 120°F (49°C) or less to avoid product damage.

Enzymes and other food preserving ingredients, such as yeast, are protected from damage by drying at low tem-

peratures and low dewpoints. Dozens of food and drug products ranging from seeds and cereal to food powders are produced with higher quality when dried at low temperature and low humidity levels. Desiccants allow the drying process to be accelerated by establishing a deep wet-bulb (wb) depression. This refers to the difference between the db and wb temperatures of the air surrounding the product and the vapor pressure at the surface of the material being dried and the vapor pressure in the air.
