VIBRATING DRYERS Drying and Mixing

What is a Vibrating Dryer?

A vibrating dryer is equipment that generates high-speed circular vibrations of the drying chamber on springs, agitates powder using only vibration, and dries materials through indirect heating under vacuum conditions.

FEATURES

  • Contamination‑Free Drying!

    The drying chamber is vibrated so that the powder is agitated only by vibration (i.e., there are no agitator blades inside the drying chamber). As a result:

    • No contamination from agitator blade shaft seals
    • No contamination due to wear of agitator blades
    • Minimal contamination due to wear of the chamber

    In addition, a wide range of linings is available to prevent various types of contamination.

    Note: "No foreign matter contamination" refers to "contamination-free" or "contami-free."

    Foreign matter can easily enter through the shaft seal section.
    Simple structure without agitator blades prevents foreign matter contamination.

  • Wide variety of materials
    can be dried!

    • Materials requiring drying at constant temperature (capable of drying from low to high temperatures)
    • Materials containing organic solvents
    • Slurry, paste, and cake-form materials
    • Nano-particle materials
    Slurry-form material
    Paste-form material
    Cake-form material

  • Improves work efficiency!

    • Easy to clean and maintain because of its simple structure
      • Nothing inside the chamber
      • Easy nozzle opening and closing
      • External chamber surface can be cleaned (insulation material does not get wet even when water is applied)
    • Vibration facilitates material discharge
    • Easy to automate
