Excerpts from the report Foreword: Under present marketing methods, most agricultural products are graded, sorted, or divided into groups in producing areas in order to channel each type of product into its best market or use. These sorting or grading operations require a great deal of labor, which is often difficult to recruit during the harvest season and is becoming increasingly costly. This study was made to determine some principles which, if applied, would reduce the labor requirements for grading without impairing inspection efficiency. The principles developed in this study are based on tests with cylinders, ellipsoids, and spheroids. As the laboratory specimens used more nearly simulate certain fruits and vegetables than many other products, the data obtained are likely to be most applicable to such commodities. The principles developed, however, appear to be applicable to smaller agricultural products, such as tree nuts, and some other products that are conveyed or moved on tables or belts past graders. |
