Single Drum Dryers

Single Drum Dryer Description

  • Drum dryers convert viscous liquids and pastes into dry powders, flakes, or sheets
  • Standard atmospheric model consists of single heated drum supported on trunnions that turn in journal or roller type bearings
  • Feed materials are applied to drum with splash or dip devices, or with applicator rolls
  • Heat conducted through drum wall evaporates moisture from wet product film during partial revolution of drum
  • Single layer applications dry to a lacy sheet or flake
  • Multiple layer applications dry to uniform thickness and density with minimum dusting tendencies
  • Can be equipped with "satellite" applicator rolls spaced around periphery of drum to eliminate void areas, permit drying between successive layers of fresh material, and form thick, consistent product sheets gradually
  • Mechanical support skids are available for single drum dryers
