Grains are agricultural products that often experience post-harvest damage, one of which is corn. Based on the standard SNI 014483-1998 quality requirements that must be met by corn is to have a moisture content of 14%. To maintain the quality and value of agricultural products, the drying method is used. In general, post-harvest drying is only done naturally by drying using heat from solar energy or commonly called conventional drying. In this study, the drying process used a fluidized bed dryer. The purpose of this study was to determine the minimum fluidization velocity of corn in fluidized bed drying. In this research the minimum fluidization velocity was 4.10 m/s.
