Highly integrated sensors for in-line detection of granulation state in fluidised bed reactors (A07)

• Subject Area: Mechanical Process Engineering
• Term: since 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 503850735

In this project novel Lagrangian sensor particles will be developed, which allow the measurement of temperature, humidity and applied coating layer thickness during fluidized bed spray granulation based on impedance spectroscopy. The first prototype is of 25 mm size, whereby further miniaturization to 5 mm will be achieved by designing and fabricating an application specific integrated circuit (ASIC). Particle position will be measured by a magnetic particle tracking setup, which is for the first time adapted to a fluidized bed spray granulation process.
