Coating - Various Styles

Precision Coater™ - Patented

Bottom-spray fluid bed coating

Precision coating of small particles such as powders, granules, crystals, pellets and small tablets

The Precision Coater™(Patented) offers precise coating of particles from 50 - 5000µ. The coating liquid is sprayed up into to a fluidized bed which uses advanced fluid dynamics to control the flow and achieve a high degree of coating uniformity.

Capacity: from 200g to several ton/batch

Top-spray fluid bed coating

Cost-effective pellet coating

In the Top Spray Coater™, particles to be coated are suspended in the fluidized bed, and the coating liquid is sprayed down on to them from above.

Capacity: from 50g to several ton/batch

Wet granulation pelletization

Granulating and spheronizing a powder mixture

The active substance is mixed with 5-30% microcrystalling cellulose and the mixture granulated with water or an organic solvent. The granules are then compacted and spheronized. This operation can be performed using the Roto - Processor™ or Pellet - Processor™.

Spray drying coating

Efficient continuous coating of fine powders

The GEA Niro Pharma Spray Dryer™ is used to coat fine powders. The particles are suspended in a polymer solution, then spray dried.

Capacity: up to several ton/hr
