The aim of this research was the development of an accurate, robust and reliable electrical capacitance tomography (ECT) sensor for the online measurement of solids concentration and moisture content profiles of fluidised bed dryers. In the pharmaceutical industry, fluidised bed dryers are used to dry wet particles prior to compression. Although electrical capacitance tomography (ECT) has been traditionally used to obtain images of the fluidisation processes, in this research, capacitance measurements from an ECT sensor mounted on a lab-scale fluidised bed dryer were used to estimate solids concentration and moisture content profiles. The effects of the process parameters, such as particle size, gas velocity, inlet gas temperature and relative humidity, on the moisture content of solids in the batch fluidlsed bed have been analysed theoretically.
