Simulation of a continuous fluidised bed dryer for shelled corn

Abstract

In this study, a mathematical model to simulate the drying of shelled corn in a continuous plug-flow fluidised bed dryer is presented. Equipment and material models were applied to describe the process. The equipment model was based on the differential equations obtained by applying mass and energy balances to each element of the dryer. In the case of the material model, mass and heat transfer rates in a single isolated particle were considered. Calculation results were verified by comparison with experimental data from the literature. There was a very good agreement between experimental data and simulation. The effects of gas temperature and velocity, particle diameter, dry solid flow and solid temperature on the drying process were investigated. It was found that the changes in gas velocity, dry solids flow and the solid temperature had essentially no effect on the drying process.

“…5 and 6. Similar results were reported by Khanali et al (2013), Alonso andPicado (2021), andNilsson (1986) for rough rice, shelled corn, and apatite granules, respectively. However, a linear decreasing moisture content profile along the length of a continuous plug-flow fluidised bed dryer was also reported in the literature (Izadifar and Mowla, 2003).…”

“…And it has been reported that residual moisture evaporated by conductive heat transfer, thus leading to a lower moisture content in a shorter time. Purple yam (Santos et al, 2022) in RWD, tomato (Castoldi et al, 2015), corn (Alonso and Picado, 2021) and pumpkin (Mujaffar and Ramsumair, 2019) in FBD, persimmon (Jia et al, 2019) and sweet potato (Onwude et al, 2019) in CD was founded in literature. The results are in agreement with the literature.…”
