Abstract
In Japan, most grain related common facilities are built for drying and processing of grain, with Pool processing systems. The user is charged the costs based on the ratio of their individual volume of shipment and the total throughput. After the common facility receives the grain, the grain is sampled and dried with a test dryer. The costs are calculated after husking and sorting of the grain, so precision of the self-inspection device influences the cost of the grain processing. In this study, the performance of a self-inspection device newly developed for several kinds of grains was investigated. For paddy, wheat and large soybean, the recovery rate of whole grain from the whole grain pack greater than 97 %. This recovery rate is the ratio of the weight of whole grain in the samples and the weight of samples recovered from the whole grain pack. According to the inspection results, the precision of whole grain ratio and filtering ability of the self-inspection device of this study was almost equal to that of a conventional self-inspection device for one kind of grain. Therefore, the self-inspection device introduced in this study is feasible for actual use in cooperative grain drying processing facilities.
