Abstract
Excerpts from the report: The objectives of the research were to investigate the cause and extent of physical damage (breakage) to various grains by different commercial handling methods and to provide data that will point to remedial and corrective measures for minimizing grain breakage. Full-scale grain-handling equipment of commercial sizes and capacities was used in the study. The entire quantity of grain in each test was analyzed to determine the amount of breakage in each handling method studied. This eliminated sampling errors that occur when small samples are obtained from sizable grain lots. The five grains used in the tests were yellow corn, yellow soybeans, hard red spring wheat, hard red winter wheat, and dry edible pea beans.
