The present invention relates to a rice grain scattering device of the frozen rice manufacturing apparatus, the conveying conveyor for continuously supplying the cooked grain; A roll brush installed on the conveying conveyor to scatter the grain continuously fed; And a compressed air spraying unit installed adjacent to the roll brush in the conveying conveyor traveling direction and spraying compressed air to the grain disposed on the conveying conveyor to scatter the grains, and cooling the compressed air spraying unit. Including the unit, the roll brush is only used once and the compressed air is sprayed instead of using the roll brush twice or three times to scatter the rice, thus preventing the rice grains from being crushed by using the roll brush. It has an effect that can scatter efficiently.In addition, since the compressed air is further included in the compressed air injection unit, the compressed air is cooled before being injected, so that the rice is scattered by the compressed air and simultaneously cooled. Therefore, the pre-cooled rice is frozen in the next step of freezing, so the freezing time of the rice can be reduced, and the temperature difference between the temperature of the rice and the freezer of the freezing process decreases, thereby improving the heat transfer efficiency according to the 2 laws of thermodynamics, thereby freezing efficiency. It can improve the cost and reduce the cost in the frozen rice manufacturing process.Frozen grain, freezing device, condensation, frozen rice, scattering, separating device본 발명은 냉동밥 제조장치 중 밥알 스캐터링장치에 관한 것으로서, 취반된 곡물을 연속적으로 공급시키는 이송컨베이어; 상기 이송컨베이어 상에 설치되어 연속적으로 공급되는 상기 곡물을 스캐터링(scattering)시키는 롤브러쉬; 및 상기 롤브러쉬에 상기 이송컨베이어 진행방향으로 인접하여 설치되어 상기 이송컨베이어 상에 배치된 상기 곡물에 압축공기를 분사시켜 상기 곡물을 스캐터링시키는 압축공기분사부를 포함하고, 상기 압축공기분사부에 냉각유닛을 더 포함하여 종래에 롤브러쉬를 2회 내지 3회 정도 사용하여 밥을 스캐터링 하는 것보다 롤브러쉬를 1회만 사용하고 압축공기를 분사시키므로, 롤브러쉬 사용에 따른 밥알의 으깨짐을 방지하면서도 밥을 효율적으로 스캐터링할 수 있는 효과를 갖는다.또한, 압축공기분사부에 냉각유닛을 더 포함하여 압축공기는 분사되기 전에 냉각되므로, 밥이 압축
