| Description
| - The effect of primary particle surface wettability by a binder solution on the rate of agglomeration in a fluid-bed top-spray granulation process was investigated. A model system consisting of hydrophilic and hydrophobic spherical primary particles with a narrow size distribution, and an aqueous solution of hydroxy propyl-cellulose (HPC) as binder, was used. The surface energy of the primary particles was measured by inverse gas chromatography (IGC) and their wettability was characterised by static and dynamic contact angle. Granulation was carried out in a desktop fluid-bed granulator and the resulting granule size distribution and granule microstructure were analysed. The hydrophobic particles gave a wider granule size distribution (larger maximum granule size) than hydrophilic ones under otherwise identical conditions, and the granules were notably rounder and more compact. However, the fraction of un-granulated fines was also higher in the case of hydrophobic primary particles. SEM analysis of gra

- Práce jako první přímo ukazuje vztah mezi povrchovou energií a tedy smáčivostí primárních částic a kinetikou jejich granulace ve fluidní vrstvě. Pomocí inverzní plynové chromatografie byl charakterizován povrch částic a bylo dokázáno, že existuje optimální hydrofobní charakter částic, který maximalizuje nárůst granulí. Totéž bylo potvrzeno pomocí počítačové simulace. (cs)
