Solutions for Drying, Granulating and Coating Small Particles

All Romaco Innojet solutions for drying, granulation and coating small particles are based on the air flow bed technology originally developed and internationally patented by Dr. h.c. Herbert Hüttlin. This method optimises the fluidisation of solid particles and creates flow conditions that enable extremely gentle intermixing of the product. The air flow bed technology provides significant benefits for our customers compared to granulation and coating systems based on a conventional fluidised bed.

Characteristics of the Air Flow Bed Technology

  • Gentle product flow owing to the orbital, and hence controlled, flow of process air
  • Particles float freely without any friction because the product hovers, resulting in rapid, and above all even, coating with the material
  • Shorter processing times combined with excellent, reproducible product quality

Highlights:

 

  • Drying, granulation and coating combined in a single batch process (3-in-1)
  • Multilayer coating: seamless sequence of individual spraying steps
  • Drying times up to 25% shorter
  • Higher productivity compared to conventional, conical product containers owing to the cylindrical container geometry
  • Efficient intermixing of the product with the innovative spraying system
  • Large product surface facilitates the application of liquid coating or adhesive medium
  • Cost efficient solution because spray loss is reduced to a minimum
  • Reliable processing even of highly friable products
  • Efficient coating of complex geometries as well as products and particles with a hollow structure
  • Uniform flow conditions in the container owing to the cylindrical design
  • Scalable spray rate because there is only one, central nozzle
  • Nozzle designed with a spraying gap: the gap length can be varied proportionally but the geometry remains constant
  • Stable droplet sizes regardless of the spray volume

 

The VENTILUS® series is available as laboratory, pilot or production scale equipment and deployed successfully in the pharmaceutical, food and chemical industries.
