The specific heat of Japanese rice at different stages of milling was measured. The specific heat of rough rice was measured by an adiabatic calorimeter, husked rice by a modified ice calorimeter and fully milled rice by a twin calorimeter. Their specific heat values were slightly lower than foreign rices. The relationship between the specific heat of rough rice and moisture content is indicated by the following regression equation: C=0.0112 W+O.217, moisture content 9.8% to 23% where C is specific heat (cal/g °C) and W is moisture content (%). For husked rice and fully milled rice, measurements were made in lower ranges of moisture content. The relationship between the specific heat and moisture content was indicated by two segments with one break, and the regression equations were: For husked rice (Nihonbare), C=0.117+0.240, moisture content below 9.2%, C=0.00805 W+0.272, moisture content 9.2% to 14%, For husked rice (Koshihikari) C=0.0109 W+0.234, moisture content below 9.2%, C=0.00803 W+0.262, moisture content 9.2% to 15%, For fully milled rice (Koshihikari) C=0.0121 W+0.217, moisture content below 9.4%, C=0.00801 W+0.255, moisture content 9.4% to 15.5%.

20℃・200gの水を100℃にするために必要なエネルギーは1,600(cal) そこから20gを気化させるエネルギーが20(g)*539.8(cal)=10,796(cal) 米の比熱はなんと論文があったので引用すると、白米コシヒカリで1.065cal/g℃ 米1合(20℃)だと150(g)*80(℃)*1.065=12,780(cal) https://t.co/mZ1KZ03n0Q
