Moisture Content Determination

Abstract Principles are discussed for determining moisture content of individual peanut, Arachis hypogaea L., kernels by microwave resonator measurements, and data illustrating the application of these principles are presented. By measuring the shift in the resonant frequency and the change in the cavity transmission characteristics when a peanut kernel is inserted into the cavity, and taking the ratio of these two parameters, it is possible to obtain the moisture content of the kernel independent of its mass (size) and apparently independent of peanut type, as far as runner and virginia market types are concerned. Moisture contents in the range from 4 to 14 percent, wet basis, were determined with an uncertainty of 0.9 percent moisture, at the 95-percent confidence level.

Dielectric Objects

ABSTRACTMicrowave resonators have been found to be sensitive devices for sorting dielectric objects of irregular shapes according to their volumes, for detecting voids inside objects of similar shape or for determining moisture content in objects of varying volumes. Fundamental principles of operation as well as experimental results are discussed in the paper.
