PURPOSE:To simplify drive through a simplified mechanism by a method wherein grains in a storage part are circulated in a manner to return them to the storage part through a drying part only through drive of a single chain conveyor. CONSTITUTION:When a feed cover 12 located to the side of a machine body 1 is released and grains are charged, the grains flows in a conveyance gutter 40 through a support gutter 10. The grains are orderly conveyed in the rotating direction of a chain conveyor 5 in association of a lateral moving process part 5a of the chain conveyor and the conveyance gutter 40. The grains are fed in a cylinder body 45 horizontally spanned over the upper surface of the machine body 1 and charged in a storage part (a) through a long opening 48 formed in the bottom thereof. Thus, the grains are gradually accumulated and its upper layer surface G is brought into a state in which the storage part (a) is full of the grains to the rear end side. With this state, charging of the grains is stopped, and by rotating the chain conveyor 5 as the grains are controlled and delivered through operation of a shutter (e), the grains are circulated through a flow-down passage 20. This constitution simplifies structure and the shape of a mechanism and simplifies a drive means.
