Abstract
An on-line drying control method for powdered or granular materials and a related system to execute the method. A fixed amount of materials stored and dried in a drying means such as a hopper dryer is sampled, transported into a moisture measuring/operating station wherein the sampled materials are heated in a heat treatment chamber and the moisture content is calculated by an operation unit. The moisture content is sent to a temperature controller to control the temperature of the drying means so that the obtained moisture content corresponds to a predetermined moisture content while comparing both moisture contents.
