METHOD FOR PROCESSING OF SUNFLOWER OR RAPE EXTRACTION CAKE (VERSIONS) Russian patent published in 2015 - IPC A23J1/14 A23J3/14 

FIELD: food industry.

SUBSTANCE: invention relates to food industry, fodder industry. The method involves protein and carbohydrates extraction from the extraction cake by way of introduction of alkali water solution with 5-20% concentration into a suspension prepared of a mixture of extraction cake and water at a ratio of 1:5-10 till the suspension acidity index (pH) is within the interval of 8.5-9.5. The suspension is maintained during 45-60 minutes at a temperature of 45-55°C. One performs preliminary purification of the extract where the suspension is supplied onto a decanter to produce an extract and a solid phase (cake, "НБВ") for subsequent stages of drying and granulation. One proceeds with final purification of the extract in a high-rate separator to produce the purified extract and a solid phase (residuum) for subsequent stages of drying and granulation, preliminary isolation of the purified extract protein by way of ultrafiltration and protein final concentration by way of moisture evaporation at low temperatures with protein subsequent delivery for drying to produce a sunflower or rape protein concentrate (SPC/RPC). One performs preliminary isolation of carbohydrates, passed through a UF membrane installation, in a reverse filtration osmosis installation to produce saccharide solution and carbohydrates final concentration by way of moisture evaporation to produce saccharide syrup (SS). Alternatively, the method version is implemented only at the stage of the extract preliminary purification; the extract passes through the second decanter to produce a solid phase and a purified extract; at the stage of the extract final purification, the solid phase (residuum) is mixed with the solid phase (cake, "НБВ") released from the second decanter for subsequent stages of granulation and drying.

EFFECT: inventions group allows to manufacture extraction cake processing products - SPC/RPC, "НБВ" and SS of high quality and expand the range of extraction cake products manufacture technologies.
