The previously mentioned Soluble Coffee powder is further processed into agglomerated coffee, by the process of converting the coffee powder into granules.
The process of agglomeration involves getting smaller particles to adhere to each other to form a powder consisting of bigger conglomerates/agglomerates, which are essential for an easy reconstitution of coffee in water.
In cases where spray dried powders require further agglomeration, an additional process stage is used involving powder wetting, after drying and cooling. Control of wetting is carried out with water and/or saturated steam in an agglomeration chamber equipped with a rotating impactor. The agglomerates are then dried and cooled in the attached fluid bed, followed by sieving and packing. Fines and oversize fractions are reprocessed within the agglomeration plant.
