PROBLEM TO BE SOLVED: To solve a problem wherein a large grain moisture difference between grain already loaded in a storage chamber etc. of a grain dryer and grain additionally loaded in the storage chamber easily causes moisture unevenness when new grain is additionally loaded in grain in the ventilating circulation carrying state, by performing loading control to reduce moisture unevenness in the additional loading process. SOLUTION: In this circulation type grain dryer, grain supplied from a grain lift 1 is stored in a storage chamber 2, and while the grain is made to flow down from the storage chamber 2 through ventilation drying chambers 4 by rotation of delivery valves 3, ventilation and drying are performed. Drying control is performed by circulating and carrying the grain from a grain collecting chamber 5 to the grain lift 1. With respect to loading and drying action for performing drying of initial grain load, by detecting subsequent additional loading action, a delivery amount of the delivery valves 3 is reduced and controlled to perform the load.
