Abstract
Un proceso para extraer impurezas sólidas suspendidas de un licor de azúcar que es jugo evaporado de azúcar de cana o sirope de afinación, formando en dicho licor un flóculo primario de fosfato de calcio insoluble que contenga dichas impurezas suspendidas, aereando con agitación el licor que contiene el flóculo primario, distribuyendo uniformemente de 1 a 20 y más preferiblemente de 5 a 15, partes por peso de agente aniónico floculante por millón de partes por peso de azúcar en el licor para iniciar la formación de un flóculo secundario en el mismo, reteniendo la mezcla resultante durante de 15 segundo a 5 minutos, preferiblemente de 30 segundos a 3 mininitos, en un recipiente floculador con agitación no turbulenta evitando la segregación del flóculo secundario del licor y permitiendo crecer al flóculo secundario, transfiriendo el licor que contiene al flóculo secundario sin agitación adicional desde el recipiente floculador a un recipiente separador, permitiendo al flóculo secundario segregar por flotación desde el licor en el recipiente separador, y sacando separadamente licor clarificado y sólidos floculados del recipiente separador, caracterizado en que el flóculo primario se forma agregando una sal de fosfato soluble al licor, y que el agente floculante usado para formar el flóculo secundario es un polímero con un peso molecular de desde un millón a 10 millones conteniendo de 50 a 80 moles por ciento de unidades acrilamidas y de 50 a 20 moles por ciento de ácido acrílico y/o unidades de acrilato.A process to extract suspended solid impurities from a sugar liquor that is evaporated sugar cane juice or refining syrup, forming in said liquor a primary floc of insoluble calcium phosphate containing said suspended impurities, aerating the liquor it contains the primary floc, uniformly distributing 1 to 20 and more preferably 5 to 15, parts by weight of flocculating anionic agent per million parts by weight of sugar in the liquor to initiate the formation of a secondary floc therein, retaining the resulting mixture for 15 seconds to 5 minutes, preferably 30 seconds to 3 min., in a flocculator container with non-turbulent agitation avoiding the segregation of the secondary floc of the liquor and allowing the secondary floc to grow, transferring the liquor it contains to the secondary floc without additional agitation from the flocculating vessel to a separating vessel, allowing the secondary floc segregate by flotation from the liquor into the separator container, and separately removing clarified liquor and flocculated solids from the separator container, characterized in that the primary floc is formed by adding a soluble phosphate salt to the liquor, and that the flocculating agent used to form the floc Secondary is a polymer with a molecular weight of from one million to 10 million containing 50 to 80 mole percent acrylamide units and 50 to 20 mole percent acrylic acid and / or acrylate units.
