Abstract
A method of producing sugar through the recycling of a carbonation scum produced after a first carbonation of a sugar juice treated with a lime milk comprises separating the scum after the first carbonation. The scum-free sugar juice is then filtered for producing sugar. An amount of the separated scum is diluted with water. After diluting, the pH of the diluted scum is adjusted, and a thick portion of the amount of the scum is separated and activated. The activated thick portion of the scum is then recycled for introduction with a sugar juice.
Claims3
A method of producing sugar through a recycling of carbonation scum produced after a first carbonation of a sugar juice treated with a lime milk, the method comprising:
- separating the scum after the first carbonation of the lime-treated sugar juice;
- filtering a scum-free sugar juice for producing sugar;
- diluting an amount of the separated scum with water to a density ranging form 1010 to 1350 kg/m.sup.3 ;
- adjusting the pH of the diluted scum to a pH value ranging from 6.00 to 11.20 by mixing the diluted scum with carbon dioxide (CO.sub.2);
- after adjusting the pH, separating a thick portion from the diluted scum;
- activating the thick portion of the scum;
- and
- recycling the activated thick portion of the scum for introduction with a sugar juice.
