Abstract: | In malt production drying operation plays an important role in the total processing cost, however there are not many studies on malt drying modeling and optimization.
In this paper a deep layer malt drying mathematical model in the form of four partial differential equations is presented.
To determine drying constants, malt thin layer drying experiments at several air temperatures and relative humidities were made.
The model were validated at industrial scale. The greatest energy savings, approximately 5 5% in fuel and 7.5% in electric energy, were obtained by an additional (and increased) air recirculation, which is carried out during the last 6 hours of the drying process and a significant decrease of air flow-rate during the last 6 hours of the drying process. |
