METHOD FOR DOUBLE CENTRIFUGATION FOR PURIFICATION OF NUTRITIONAL OIL Russian patent published in 2022 - IPC C12P7/64 C11B1/02 

FIELD: biotechnology.

SUBSTANCE: method for increasing the yield of a product – oil with polyunsaturated fatty acids (options) is proposed. The method includes at least two stages of centrifugation of a mixture of cell material, oil, water and other compounds necessary for fermentation. At the same time, a product of a light phase of the first centrifugation stage comes to a centrifuge of the second centrifugation stage, and a product of a heavy chain is discarded, and a separation cutoff after the first centrifugation stage is carried out inside the heavy phase. After the second centrifugation stage, a product of a light phase is preserved, and a product of a heavy phase is recirculated to the mixture of cell material, oil, water and other compounds necessary for fermentation.

EFFECT: inventions prevent losses of the yield of the target product, while maintaining its quality.
