Microwave drying

AIF-Project with Brick and Tile Research Institute Essen Regd. and Materialforschungs- und -prüfanstalt an der Bauhaus-Universität Weimar (2020-2022)

Drying is a key process in the brick producing industry as it has a major impact on the overall energy consumption of the production and furthermore also on the final product quality. So far, conventional convective drying is applied. This has, in combination with the burning process, a very low energy efficiency. We therefore propose the combination of classical convective drying with intermittent microwave heating. First lab scale and pilot scale experiments already revealed the feasibility of this approach. In an upcoming joint project with our partners Brick and Tile Research Institute Essen Regd. and Materialforschungs- und -prüfanstalt an der Bauhaus-Universität Weimar we plan to investigate the drying process theoretically based on macroscale heat and mass transfer modeling combined with simulations of the electromagnetic field.
