  • Drying of Polymer (including Dehumidifying Dryers,

    3 Low Pressure Dryers or Vacuum Dryers . Low Pressure Dryers or Vacuum Dryers accelerate the plastic material drying process by using a vacuum to lower the boiling point of water from 100 °C to 56 °C. The moisture is rapidly extracted from the heated material. Leaving it in a condition to be moulded or extruded.

    2020-5-21 · Rotary drums allow for a constant dew point suitable for the material that needs to be processed. This technology uses a rotating wheel with a desiccant agent to dry the service material. Rotary drums can be 40% more efficient than dehumidifying dryers. Low pressure dryers or vacuum dryers eliminate moisture without the help of a desiccant.
