ABSTRACT

 

Dielectric properties of wood have both theoretical and industrial applications. They also provide a better understanding of the molecular structure of wood and wood-water interactions. Dielectric properties of wood were affected significantly by moisture content for all anisotropic directions. The dielectric properties of Borassus flabellifier (BF) were investigated in two anisotropic directions along and perpendicular direction of fibers of wood part the natural juice Neera is collected over night from male BF tree and female BF tree. All the measurement were taken on room temperature, fixed value(s): AC Volt [Vrms] =1.000 and at frequency range from 1.00Hz. to 4.0x107 Hz. The dielectric constants were measured by four probe method. The capacitance measurements have been made at various frequencies knowing the geometrical dimensions of the pellets. The quality factor was derived in the same frequency range and temperature. Characterization of the samples was made by scanning electron Microscope (SEM) model JEOL JSM5400. The results shows that the capacitance and quality factor are slight different in male and female BF wood considerably. The dielectric measuring device used in this study at UGC-DAE Consortium for Scientific Research Centre Indore, Madhya Pradesh, India. In this study the drying of wood done by microwave energy using a continuous microwave drier was compared to that by conventional method.
