Abstract (en)

[origin: EP0957178A2] Method for the preparation of white sugar of commercial quality from raw beet sugar, including the following operations: a) microfiltration or ultrafiltration of the juice, after separating the organic and mineral particles whose size is above 50 microns, using membranes whose size is between 5000 MWCO and 0.5 micron; b) juice sweetening; c) juice concentration in multi-effect evaporators; d) cooling crystallisation of the juice thus obtained; e) separation and washing of the crystals. <IMAGE>
