  • Page 18: Structure Characteristics And Working Principle

    2. Structure Characteristics and Working Principle 2.1 Working Principle Moisture hot air from drying hopper is blown into rotor after flowing through cooler. Moisture from the air is dried by rotor and is then adsorbed by regeneration heating air. Two strands of airflow function on the rotor. And with the rotation, moisture from the air is absorbed and expelled after absorbed regeneration air to form stable low dew-point air, which is dried and heated to the drying temperature and then is blown into material barrel to closed circle to dry material.

  • Page 19: Why Choose Sdd

    2.3 Why Choose SDD For these quality deficiencies as bubble, crazing, cracking, poor transparency are due to insufficient drying of plastic materials before molding, and the engineering plastics such as: PC, PA, PBT, PET, Nylon, etc. The hygroscopic materials used in the plastics industry such as PC, PA, PBT, PET, Nylon, etc.
