Technical Abstract: Dielectric properties ( ', '') of ground samples of peanut (Arachis hypogaea L.) pods and kernels were measured for several densities, temperatures, and moisture contents, in the range of 300 to 3000 MHz. Dielectric mixture equations were used to correlate the dielectric properties with density. The coefficients of quadratic and linear dielectric mixture equtions are tabulated for 915 and 2450 MHz, for different temperatures and moisture contents. The values of the dielectric constants ( ') and loss factors ( '') of bulk peanut pods and kernels were determined by extrapolation of the first and second-order polynomials that relate ( ') and ( '') with denisty. An equation that determines the dielectric properties of bulk peanut pods and kernels as a function of their temperature and moisture content was determined using multiple linear regression.
