Drying furnace applications: from the raw material morphology centrifuge cake; freely flowing powder. Granules, flakes, fibers and other materials dry. From the drum dryer mechanism can be divided into direct or indirect heating, ventilation tube heating steam pipe indirect heating, double heating and other structural forms. From the drying temperature may be from 60 ° -600 ° range of choice, in principle the higher the temperature, the higher the evaporation intensity.
