Abstract

This paper describes an experimental study on drying process in a novel configuration of fluidized bed, namely jetting fountain fluidized bed, and in conventional fluidized bed as well. The experiments have been carried out using a fluidized bed of 105 mm inner diameter. Fenugreek seeds have been used as bed materials to be dried. The influences of different parameters on drying process have been investigated. Those include bed temperature, air fluidization velocity, and jet air ratio and jet height. The experimental results demonstrate that the drying rate increases with the increase in jet air ratio and inlet air temperature. Jetting fountain configuration enables greater drying rates compared to conventional operation.
