What Does a Drum Dryer do?

Operating Principle of a Single or Double Drum Dryer

A drum dryer is basically a conduction dryer. A wet feed film (in liquid or paste form) is applied to a rotating metal cylinder or a pair of metallic cylinders, that are heated inside with steam. Material film dries to the final moisture level and is scraped off the drums via a set of knife-blades.

Special Features of a Drum Dryer:
  • Suitable for handling liquid or pasty feeds.
  • Product in powdery, flaky form.
  • Uniform drying due to uniform application of film.
  • Medium range capacities.
  • Very High thermal efficiency.
  • Minimum Thermal degradation.
  • Continuous operation.
  • Accomplishment of drying in single step, eliminating need for any intermediate concentration processes.
