A single-cavity microwave heating system has been designed and fabricated for microwave-assisted extraction of carrageenans from seaweed. The system comprises a single mode (TE101) waveguide fitted with power and temperature controls, together with a continuous-flow-recycle reactor operating at atmospheric pressure. The system has been tested by extraction(More)
During cheese manufacture the moisture content of the curd must be carefully controlled. Curd moisture is usually measured by weighing and drying, which is a time consuming process. This paper describes progress in the development of microwave moisture sensing equipment suitable for the cheese industry. Results from a permittivity survey are described. A(More)
This paper presents one-dimensional and two-dimensional Microwave Inverse Computing methods to detect an internal object using a signal applied from the surface of the host material. The modelling of our application system has been aimed towards the in-vivo detection of a breast tumour, in particular, and to enable the calculation of the tumour size and its(More)
