Spray Granulation

Spray Granulation covers SINOTHERMO's PGL fluidized bed spray granulator, which sprays liquid binder onto a fluidized powder bed to grow uniform, free-flowing granules. This single-chamber process combines mixing, granulating and drying with fine control over final granule size.

PGL-Fluidized Bed Spray Granulator

Categories: Granulator and Extruder, Fluid Bed Granulator

Combines Mixing, Granulating and Drying for High-Excipient Granulation:

Excipient-rich granulation finds an ideal match in this unit. Excipients in the hopper form a fluidized bed that acts as seeds or carriers, while the main material — typically a liquid extract making up a smaller proportion of the batch — is sprayed from above and merges at the bed's edge for granulation. This method is particularly suited to heat-sensitive materials.

Input:: Carrier materials in powder form, main material in liquid form
Output:: Solid medium-sized granules, 3%–5% moisture content
Type:: Spray Fluidized Bed, Wet Granulation
Additional Features:: Mixing, Drying, Cooling

Building Granules by Spraying Binder onto a Fluidized Powder Bed

The PGL fluidized bed spray granulator sprays liquid binder onto powder suspended in a fluidized air stream, growing granule size progressively as the spray deposits and dries layer by layer within the same chamber.

Spray Granulation Process Benefits

Combines mixing, granulating and drying in a single continuous fluidized-bed operation. Gives fine control over final granule size by adjusting spray rate and fluidization conditions. Suited to instant powders, engineered particles and pharmaceutical granules needing uniform, free-flowing structure.
