Abstract

An apparatus for the measurement of the quality parameters of granular materials includes a loader assembly which delivers precise volume samples of granular material to a meter assembly which measures the moisture content. The apparatus also includes a sieve assembly which separates the samples into fractions according to kernel size. A scale assembly weighs the fractions and feeds this information to a computer which controls the apparatus and calculates the moisture content, density and percentage of foreign material contained in the granular material.
