PURPOSE:Rice bran and fat meat are dipped on oil heated in a cooker and they are stirred and subjected to 2-staged vacuum treatment to effect dehydration at the oil temperature, then oil is separated from the solid whereby the fat which used to be discarded as waste is converted into feed of high quality. CONSTITUTION:Fat meat and rice bran as a water-absorbing vegetable fibers are dipped in an oil such as animal or vegetable oil which is heated in a cooker and they are stirred. Then, the cooker is evacuated with light vacuum at the beginning, then with heavy vacuum to effect dehydration. Under the same vacuum conditions, they are centrifuged or squeezed to separate the oil from the solid and the solid is collected. Thus, fatty meat is dehydrated in a short time and, in addition, bad small of basis nitrogen in tissues is denatured and dissipated by hot oil. Thus, a large amount of feed rich in nutritions is obtained from fat meat. |
