摘要：
This is an extraction processing for rice bran oil. First, rice ban is quickly heated by radio frequency to inactivate lipase and to enhance stability and utilization of rice bran. Then ethanol is the extraction solvent, and rice bran oil and oil-soluble substances can be rapidly extracted by a focused ultrasound and microwave extraction system to obtain higher extraction yield. Finally, the ethanol extract is obtain by a solid-liquid separation and ethanol can be rapidly vacuum evaporated, condensate and recovery by a microwave vacuum system, The rice bran oil can be concentrated and purified in this extraction processing to avoid high-temperature oxidation. Overall, this rice bran oil extraction process is quick, energy saving and higher extraction yield and stability.此萃取米糠油的製程方法,先利用射頻快速加熱使米糠中的脂解酶失活,以提升米糠的安定性及利用性。再以乙醇作為萃取溶劑,利用聚焦式超音波和微波快速萃取米糠中的油脂和油溶性物質,並可增加米糠油的萃取率。最後再將固液分離的乙醇萃取液利用微波真空濃縮米糠油,快速低溫蒸發乙醇且冷凝回收,此可避免米糠油高溫氧化。整體而言,此米糠油的萃取製程可快速、節能並提升米糠油的萃取率及安定性。
