PURPOSE:To detect stably the water value of grains by positioning a conveyance roll below a supply device when the water value of grains is detected by a detection roll and moving the conveyance roll from below the supply device when the water value detection is not performed. CONSTITUTION:When a grain water measuring instrument is used as a grain dryer, some of grains which are circulated in the dryer and dried are supplied from the dryer onto the conveyance roll 4 through the supply device and sent into a spiral groove 2 in the outer peripheral surface of the roll 4, one by one, by the spiral groove 2 and a guide plate 5; and they are conveyed and guided along the groove 2 and supplied onto the detection roll 6, which detect the water value of crushed grains repeatedly at specific time intervals while crushing the grains. Remaining grains which are not sent in the groove 2 fall from a spiral groove 3 and returned into the dryer, so that they are circulated and dried together with grains in the dryer. Further, when the water value of the grains is not detected, the roll 4 moves from below the supply device and grains supplied from the supply device are not send in the groove 2, but returned into the dryer through a grain water measuring instrument and dried together with grains in the dryer.
