Why Coat?
Coating technology has many applications in the pharmaceutical industry for taste masking and drug release control. Fluid bed coating is particularly suitable for smaller particles and pellets.

For maximum process flexibility, Aeromatic-Fielder can supply a single Fluid Bed unit or Multi-Processor™ system with interchangeable modules.

Multi-Processor Concept
The MULTI-PROCESSOR™ has been developed by Aeromatic-Fielder to meet the industry's requirements for flexibility in unit operations and is based on the principle that one basic unit can be used for numerous processes simply by interchanging a module.The concept is available in sizes ranging from pharma development and pilot scale unit up to full production scale equipment built in compliance with current GMP and safety standards. Only the highest qualities of materials are used to build the MULTI-PROCESSOR™ giving you a long lasting and reliable unit for your process work in the pharmaceutical industry.

NEW Innovations

Tomorrow's technology today

  • FlexStream™ (patent pending), is a new Multi-Purpose Processor from Aeromatic-Fielder™ that uses proven fluid bed technology to achieve fluid bed granulation, drying and pellet coating (or tablet coating) in ONE processor. Our new fluid bed system offers multiple processing from a single bowl providing both flexibility and cost benefits.

Process Modules:

  • The Drying Module
  • The Top Spray Granulation module
  • The PRECISION-COATER™ module

Process options available are:

  • Mixing with Non Sifting Gill Plate Effect
  • Drying / Cooling
  • Particle size enhancement by spray granulation / agglomeration (Top Spray)
  • Precision-Granulation (Bottom Spray)
  • Pelletizing (Bottom or Top Spray)
  • Precision-Coater (Bottom Spray)
  • Processing of aqueous or organic media

How the Precision-Coater™ Works
The key element of the new Precision-Coater™ is the Swirl Accelerator that controls accurately the airflow properties and so the behaviour of particles flowing into the coating column. In a traditional fluidized bed coater a large proportion of the air flows into the bed around the column, which is then fully fluidized and allows the particles to flood into area around the spray nozzle by virtue of the hydrostatic head of the bed.

However in the Precision-Coater™ much more of the air is directed into the coating column via an insert plate and the swirl accelerator. This design creates a much higher process air speed adjacent to the nozzle and generates a low-pressure zone that sucks particles into the core of the coating tube. The high speed of the airflow causes the individual particles to spin allowing a much more even coating The swirl accelerator imparts a rotational component to the air stream which when combined with the high speed of the air stream ensures that the individual particles are kept separate so that it is possible to operate a much higher humidity local to the nozzle without the risk of agglomeration. Tests show that the high speed of the air stream also generates a much higher level of evaporation so that particles are dry and will not agglomerate long before they return to the bed around the coating tube.
