Purpose: The objective of this study was to develop a classification index and the grade levels for a five-grade energyefficiency classification of agricultural dryers in Korea. Methods: The classification index and the grade levels weredetermined by using the performance test data published by the FACT over the last eight years to reflect a state of the arttechnology for agricultural dryers in Korea. The five grades were designed to have the classified dryers distributed normallyover the grades with 15% for the 1st grade, 20% for the 2nd grade, 30% for the 3rd grade, 20% for the 4th grade and 15% forthe 5th grade. Results: The classification index was defined as the total amount of fuel and electrical energy consumed per1% of the wet basis moisture content evaporated from a unit mass of grain or agricultural crops during the drying process: 1MT of paddy rice for grain dryers and 1 kg of red pepper for agricultural crop dryers as the standard mass. Conclusions: Thegrade levels for the five-grade energy efficiency classification of grain dryers, kerosene dryers, and electric dryers wereproposed in terms of the classification index value.
