A method for producing brown rice cereals according to the present invention comprises: a first step of feeding multiple brown rice grains between a bottom mold and a top mold heated at 200-280°C, making the cross-section of the brown rice grains become 100-200% of the surface of the top surface of the bottom mold, and feeding the brown rice grains to the top surface of the bottom mold a second step of fitting and pressing the top mold to the bottom mold for 8-12 seconds, repeating the expansion of brown rice grains on the top surface of the bottom mold, and producing expanded brown rice grains a third step of separating the expanded brown rice grains produced in the second step grain by grain and a fourth step of mixing a combined material and the expansion brown rice grains separated grain by grain in the third step, coating the combined material on the surfaces of the expanded brown rice grains, and drying the same. Moreover, in the fourth step, 50-80 wt% of the expanded brown rice grains and 20-50% of the combined material are mixed, and the combined material is mixed with purified water, sugar, natural powder, flavoring agents, salt, and oxidant preventers. According to the present invention, in the first step, multiple brown rice grains are fed to the inner surface of the bottom mold while the cross-section of the brown rice grains is 100-200% of the area of the inner surface of the bottom mold, and salt for increasing a temperature is added after puffing. Thus, in the puffing procedure of the second step, a large quantity of a starch layer in brown rice is not leaked by penetrating through stiffness, and multiple expanded brown rice grains are attached to be easily broken. Thus, in the third step, expanded brown rice grains can easily fall grain by grain.COPYRIGHT KIPO 2017본 발명에 의한 현미시리얼의 제조방법은 200 ~ 280℃로 가열된 상부금형과 하부금형 사이에 다수의 현미를 투입하되, 다수의 현미의 단면적이 하부금형의 상부면 면적의 100 ~ 200%로 하여 다수의 현미를 하부금형의 상부면에 투입하는 제1단계, 상부금형을 하부금형에 맞대어서 8 ~ 12초 동안 가압하여 하부금형 상부면에 있는 다
