  • Rotary Dryer – Sun Food Equipments

    ROTARY DRYER WORKING PRINCIPLE. This dryer adopts direct flow type of heating with heat source from firing unit. The material to be dried is pushed back immediately by spiral board when enters the shell from feeding tank and feeding chute. Because the drier is installed in slope, material flows to the back end under gravity and rotation force ...

  • Rotary Dryers

    Co-Current Rotary Dryers are the most widely used and are particularly suitable for drying materials containing a high moisture content, which are heat sensitive or have a tendency to stick or cake. The wet material is in contact with the gas at its highest temperature, which rapidly evaporates surface moisture.
