Process for refining raw sugar, in particular brown sugar from the sugar cane industry.

摘要

Process for refining a raw sugar, especially brown sugar originating from the cane sugar industry, which is characterised in that it comprises the operations: (a) of remelting the raw sugar in order to obtain a raw sugar syrup, (b) of carbonation or of phosphatation of the said raw sugar syrup, and (c) of tangential microfiltration and/or of tangential ultrafiltration of the raw sugar syrup which has undergone carbonation or phosphatation. This process is completed by the operations: (d) of decolorisation of the sugar syrup resulting from the operation (c), and (e) of crystallisation and/or demineralisation of the sugar syrup resulting from the operation (d).
