Flow Chart

Drying

The product particles are fluidized by means of an upward flowing hot air stream and are carefully dried until the required moisture content is reached.

Granulation/Agglomeration

The aim in granulation/agglomeration is to produce a dust-free and flowable granulate from powder.

Wurster Coating

The Wurster (bottom-spraying) technique produces a particularly uniform surface on the coated product.

Spray Nozzle

The spray liquid is injected into the fluid bed via a spray nozzle attached to the spray housing.
