Abstract
A process for refining a raw sugar, particularly raw sugar from the sugar cane sugar industry, characterized in that it comprises the steps of: (a) remelting of the raw sugar for obtaining a raw sugar syrup, (b) carbonatation or phosphatation of said raw sugar syrup, and (c) tangential microfiltration and/or tangential ultrafiltration of the raw sugar syrup, which has been subjected to carbonatation or phosphatation. The process is completed by the steps of: (d) decolorization of the sugar syrup resulting from step (c), and (e) crystallization and/or demineralization of the sugar syrup resulting from step (d).
Claims8
A process for refining a raw sugar, comprising the steps of:
- (a) remelting of the raw sugar for obtaining a raw sugar syrup;
- (b) carbonatation or phosphatation of said raw sugar syrup, and
- (c) tangential microfiltration and/or tangential ultrafiltration of the raw sugar syrup, which has been subjected to said carbonatation or phosphatation and further comprising a step of flocculation using a flocculating agent, said step of flocculation performed simultaneously with said step (b) or before or after said step (b), wherein said raw sugar to be refined has a dry matter content of 97 to 99% by weight.
The process according to any of the preceding claims, wherein the carbonatation or phosphatation, flocculation and tangential microfiltration and/or tangential ultrafiltration steps are implemented at a temperature of 70.degree. to 95.degree. C.
