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.
