GRANULATION METHOD AND DEVICE

PROBLEM TO BE SOLVED: To provide a method and a device for continuously granulating spherical granules containing plural grains, usable for broadcast sowing such as paddy rice direct planting capable of stably securing planting depth. SOLUTION: A cord carrier 7 is obtained by supplying a rod clayey carrier 5 and a specified quantity of grain 6 between a lower conveyer belt 1 and an upper conveyor belt 2, which are opposed vertically and have different peripheral speed each other, the grain pressed-in corded carrier 7 is supplied between a lower grooved conveyer belt 3 continuously formed with semi-circular grooves longitudinally and an upper grooved conveyor belt 4 formed with semi-circular grooves longitudinally in the same way as the lower grooved conveyer belt 3, the grain pressed-in cord carrier 7 is cut with projecting parts in the grooves of mutual upper/lower grooved conveyors 3 and 4, and, simultaneously, the cut carriers 7 are rolled to be spherically formed between the upper/lower grooved conveyers 3 and 4.
