Fluid bed granulation process comprising the steps of: - forming a fluid bed of seeds (Sl) of a chosen substance, - feeding said fluid bed with a continuous fluid flow (L) comprising a growth liquid, - inducing and maintaining a continuous vortex (V) in said fluid bed, the vortex (V) having a substantially horizontal axis, characterized in that said fluid flow (L) is fed into predetermined first zones (Zl) of said fluid bed, said first zones (Zl) being alternated to second zones (Z2) of said fluid bed in which said fluid flow (L) is not fed. |
