To provide a plant and a production method for stably producing rice oil retaining a low acid value, and excellent in quality, flavor and nutrition characteristics, and to provide rice oil obtained thereby.SOLUTION: A rice oil production plant integrally comprises: a rice milling section which has a storage part 10, a rice milling part 20, a bran separation part 30 for making milled rice, and a milled rice storage part 40； and an oil squeezing section which has a bran supply line 50 directly connected to the bran separation part, and transporting rice bran by air current transportation, a fixed amount supply machine 70 charged with rice bran transported by the line and sending out a fixed amount of rice bran, a fixed amount rice bran supply line 80 having a pipe conduit for transporting a fixed amount of rice bran sent out by the supply machine, a heating/water adding machine 90 heating/adding water to supplied rice bran, and a compressing machine 110 compressing rice bran supplied by the heating/water adding machine. The rice milling section and the oil squeezing section are directly connected by the pipe conduit, and fresh rice bran is supplied so as to prevent an increase in an acid value of rice bran components, and obtain rice oil excellent in the aspects of quality, flavor and nutrition characteristics.SELECTED DRAWING: Figure 1【課題】低い酸価を保持し、品質、風味、栄養特性の面で優れた米油を安定して製造する、プラント、製造方法、得られる米油の提供。【解決手段】貯蔵部１０、精米部２０、白米にする糠分離部３０、および白米貯蔵部４０とを有してなる精米区間と、糠分離部に直接接続され米糠を気流搬送により搬送する糠供給ライン５０、これにより搬送された米糠が投入され一定量の米糠を送出する定量供給機７０、供給機により送出される一定量の米糠を搬送する管路を有する定量米糠供給ライン８０、供給された米糠を加温・加水する加温・加水機９０、および前記加温・加水機より供給された米糠を圧搾する圧搾機１１０を有してなる搾油区間とを一体的に備えることを特徴とする米油製造プラント。精米区間と搾油区間を管路によって直接的に接続し、新鮮な米糠を供給することによって、米糠成分の酸価上昇を防ぎ、品質、風味、栄養特性の面で優れた米油を得る。【選択図】図１
