The present invention relates to instant boiled rice which is eaten by being restored by water from a dried state. According to the embodiment of the present invention, a method for manufacturing the instant boiled rice includes: a cooking step of cooking boiled glutinous rice； a reversing step of reversing the boiled glutinous rice by placing the boiled glutinous rice into a water tank to remove starch stained on the outer surface of each grain by separating the glutinous rice cooked in the cooking step into a grain form； a water removal step of removing water on the outer surface of the glutinous rice separated in the grain form by the reversing step； a freezing step of freezing the glutinous rice by placing the glutinous rice into a freezer supplying cold air from the lower part to the upper part while the glutinous rice in which the water is removed in the water removal step is placed into a freezing cage divided into multiple cooling plates； a drying step of drying the glutinous rice frozen in the freezing step by heating the glutinous rice at a predetermined temperature； and a crack prevention step of preventing a crack from being generated on the surface of the glutinous rice due to different temperature when glutinous rice is dried in the drying step, by partially defrosting the glutinous rice frozen in the freezing step between the freezing step and the drying step. Therefore, the method for manufacturing the instant boiled rice can rapidly manufacture the instant glutinous rice by reducing freezing time of the glutinous rice.본 발명은 건조된 상태에서 물에 의해 복원하여 취식하는 즉석 찹쌀밥에 관한 것이다. 본 발명의 실시예에 따른 즉석 찹쌀밥의 제조방법은 찹쌀밥을 짓는 취사단계, 상기 취사단계에서 취사된 찹쌀밥을 알갱이 형태로 분리하여 각 알갱이의 외면에 묻은 전분을 제거하도록 상기 찹쌀밥을 수조에 넣어 반전시키는 반전단계, 상기 반전단계를 거쳐 알갱이 형태로 분리된 찹쌀밥에 외면에 묻은 물기를 떨어내는 수분제거단계, 상기 수분제거단계에서 수분이 제거된 찹쌀밥을 복수 개의 냉각판으로 구획된 냉동케이지에 넣은 상태에서 하부에서 상부로 냉기를 공급하는 냉동기에 넣어 상기 찹쌀밥을 냉동시키는 냉동단계, 상기 냉동단계에서 냉동된 찹쌀밥을 미리 설정된 온도에서 가열하여 건조시키는 건조단계, 및 상기 냉동단계와 상기 건조단계의 사이에 상기 냉동단계에서 냉동된 찹쌀밥을 일부 해동시켜 상기 건조단계에서 건조
