Glatt spouted bed technology also enables particularly small,
particularly large or irregular products to be Agglomerated/Granulated
and Coated. The processes are very economical due to the adjustable
energy input.
No sieve bottoms
Unlike fluid bed processes, the air does not enter
the process chamber through a sieve bottom but through a longitudinal
slot.
Low flow speeds
The speed of the process air reduces considerably due to a double
expansion (in the process chamber and above the process chamber).
As a result, not even fine particles are removed from the process.
High flow speeds
In the centre of the process chamber fluidize even large or irregular
particles. The process can also be stable in the case of products
that are sticky or form lumps.

Controlled product movement
The material is transported directionally, upwards at the centre
and downwards at the sides. Nozzles at the centre spray at the point
where the material speed is highest and the energy input is greatest.
Low number of coats – Short dwell time
Agglomeration is prevented by the high material speed at the nozzle.
High spray capacities are possible even with small quantities of
material in the process chamber. In comparison with the fluid bed,
the mean dwell time therefore reduces for the same throughput.
