Abstract

In order to develop a commercially viable alternative spray drying technology, a high drying rate in a small volume must be achieved whilst maintaining a small residence time. This can be accomplished in a radial multizone dryer where high air inlet temperatures and high-G fluidization leads to enhanced drying rates. In this paper, results of CFD model are presented and validated against experimental data. The results show radial oscillations of central hot air flow with a frequency of 3.5 Hz.
