Abstract

The use of microwave is growing enormously due to its volumetric heating method. Volumetric heating method is a pollution free technique which is used for heating the complete volume of the continuous liquids, semi-solids, etc. Microwave energy has a wide range of applications which encompasses everything from heating, thawing to material processing and drying. Heating/warming of albumen is a very usual and regular practice in our food industry and microwave heating can be efficiently used for this purpose due to its selective, rapid, controlled and uniform heating. This work has been carried out to compare the efficient heating of 1-D albumen sample placed on a layer of metallic and composite supports at two different intensities of 2.5 Wcm-2 and 3 Wcm-2 processed in microwave at the microwave frequency of 2415 MHz with the support thickness of 1.5 mm. An introductory study has been carried out to find the power absorption within the albumen sample for the different cases by plotting the average power vs. sample thickness diagram. It is observed in the study that microwave power absorption is elevated for the consecutive R1 and R2 modes of significant magnitude for the suitable support thickness. It is found that the efficient heating of albumen is signalized by the large heating rate with the uniform temperature distribution within the albumen samples (minimal thermal runaway). Also the heating at the intensity of 2.5 Wcm-2 is compared to the heating intensity 3 Wcm-2. On basis of the comparisons and investigations suitable supports, support thickness, intensity of the heating is recommended as the most ideal heating conditions for albumen samples.
