PURPOSE: A method for manufacturing roasted beans is provided to make the tissue smooth to be easily eaten using far infrared ray radiated from rough germanium stones under high pressure and high temperature conditions.CONSTITUTION: Beans and rough germanium stones are injected to the heater main body(101). The main body is tightly sealed, and the beans and germanium stones injected to the main body are heated. The pressure of the main body is reduced. In the feeding process, and the beans and germanium stones are injected to the main body having circular cross section and one or more protrusions protruding to the inner side. In the heating process, the main body is heated while rotating it so that the beans and germanium stones are mixed by contacting the protrusion(105) protruding to the inner side of the main body and heated. In the heating process, heating continues until the inner pressure of the main body reaches 7.0 to 7.5 kg/cm^2 range. In the feeding process, the injected germanium stones have the size greater than that of the beans. In the heating process, heating is performed by heating the lower part of the main body(103). The size of the germanium stones injected in the feeding process is greater than the height of the protrusion.COPYRIGHT KIPO 2013본 발명은 콩과 게르마늄 원석을 가열기 본체(101)에 투입하는 공정(S120 투입 공정)과, 본체(101)를 밀폐하고 본체(101) 내에 투입된 콩과 게르마늄을 가열하는 공정(S130 가열 공정)과, 본체(101)의 압력을 감압하는 공정(S140 감압 공정)으로 이루어지는 볶음 콩 제조 방법에 관한 것으로 고압 및 고온 상태에서 게르마늄 원석으로부터 방사되는 원적외선이 콩에 작용하여 볶음 콩의 조직이 부드러워져 섭취가 용이하며, 동일한 기압에서 감압을 하는 경우에 볶음 콩의 강도가 저하되어 섭취가 용이하게 되는 한편, 가열 시간을 짧게 할 수 있는 효과가 있다.
