Description of the invention: [Technical field to which the invention pertains] The procedure for extracting miscellaneous oil from the top-flow miscellaneous carbon dioxide of the present invention is mainly based on the technique of extracting miscellaneous oil from high yield. [Prior Art] Rice is the main food of the Republic of China, and it is also the agricultural industry with the largest cultivated area and the largest number of farmers in China. Due to its climatic environment, Taiwan can produce two to two crops a year. The miscellaneous white rice has been refined (4) by-products, and about 10% of rice bran is produced in the process of precision. Rice bran contains 20% oil, which is equivalent to the soybean oil. It is the source of the cake oil. In the year, Changhua = Grease Factory used polystyrene (PCBs) as a heat medium in the process of deodorization and deodorization of miscellaneous oils. The heating pipelines caused cracks due to thermal expansion and contraction, resulting in polychlorinated biphenyls. Leakage from the line towel to the contaminated surface to the miscellaneous oil. More than 2,000 people were injured. Since then, Taiwan has made the most nutritious rice sugar into flowers, fertilizers, pickles and cultures, or as animal feed. The crude _ _ _ contains the rich vitamins such as Tianzhizhi and rice sugar. The crude rice oil also contains _f, egg self-quality, fatty acids, and phospholipids. Rice bran is a by-product of Rice Lai, although it only contains 6% of the total weight of rice, but it contains 64% of the important nutrients of rice. It is an important resource for development. At present, for the research and development of rice bran, in addition to the rice bran oil which extracts high content of rice sterol, the research and development of nutrients in the deoiled rice bran powder and the vegetarian nutrient fiber of rice bran can greatly enhance the product value of rice bran and have a good market prospect. 4 200911979 The amount of half-sweet rice is about 1.5 million, and the rice is sensitive to white. After the rice is about 150,000, the rice bran of the ant is just as the fertilizer or the animal's 22%. Considerable economic benefits make Taiwan __ food market.
