Definitions
- the present invention relates to a manufacturing process refined sugar from sweet juice, such as raw juice sugar cane or sugar beet; it also has for object an installation for the implementation of process.
- the production of refined sugar (or white sugar) at from sugar cane includes a number of treatments carried out in sugar factories followed by a certain number of additional treatments carried out in a refinery.
- the main processing steps in sweets are the extraction of sugar by grinding - pressing the cane or by diffusion which leads to a raw sweet juice, the clarification of this juice by adding lime, neutralizing the latter by carbon dioxide (in the case of beet) and decanting the juice thus treated, the concentration of the juice resulting and finally the crystallization and turbination of the sugar usually in three stages, which leads to obtaining brown sugar and molasses.
- the operations to which sugar is subjected roux are essentially a refining (washing of the crystals by a saturated aqueous solution of sugar then spinning) to remove the impurities located on the surface of the crystals, a re-solution of the resulting sugar, a clarification, a discoloration, crystallization and turbination.
- Kwock et al have proposed, in the US patent No. 5,554,227, a process leading to the production of a sugar red with low coloring called SVLC "Super Very Low color” by sequence of membrane filtration operations, softening and crystallization.
- This process allows simplification of the refining of brown sugar and in particular the elimination of refining and purification operations. It allows also the implementation of a chromatography step for recover sugar from molasses and thus improve yield sugar extraction.
- This chromatography leads generally to the production of two fractions, namely one extract rich in sugar and a raffinate containing the impurities of sugar.
- the method according to the invention comprises in in addition to a clarification of the sweet juice before pouring it submit to the tangential filtration operation; this clarification removes undissolved material.
- tangential filtration operation will be preference chosen from tangential ultrafiltration, tangential microfiltration and nanofiltration tangential; these filtration techniques, which put in suitable membranes, are well known in the art. prior art.
- the softening operation preferably comprises an ion exchange operation using an ion exchange resin (cations), for example in Na + form.
- the method according to the invention can also comprise a bleaching operation for the extract, preferably the concentrated extract, before subjecting it to the operation of crystallization; this discoloration can be constituted by treating the extract with an absorbent resin.
- the above installation may further include means of bleaching the concentrated extract from the output of concentrated extract from the means of concentration.
- the softening means include advantageously an ion exchange resin, means bringing the raffinate to the top of the softening means then being provided for the regeneration of said resin.
- the starting material used in this process is raw cane juice, for example obtained by grinding - cane pressing, which leads to a fibrous residue (bagasse) and a raw juice; alternatively, we can appeal to the diffusion technique of exhausting by hot water from the canes cut into pieces, which leads to a residue and a raw juice.
- the juice raw starter could also be raw juice of sugar beet.
- the abovementioned raw juice, which contains sugars and non-sugars is possibly subject to clarification.

- a filtration unit for example rotary filter
- the supernatant liquid (clarified juice) in the tray 9 is extracted from the latter by a circulation pump 10 discharging into a unit 11 of tangential microfiltration, tangential ultrafiltration or tangential nanofiltration.
- the supernatant thus withdrawn from the tank 9 can be reheated so that the operation in this unit 11 takes place at a temperature of the order of 70 to 99 ° C and preferably from 95 to 99 ° C.
- the membrane used in unit 11 may be of the organic type or of the mineral type (for example of TiO 2 or ZrO 2 ) and have a cut-off threshold corresponding to a molecular weight of at least 1000, good results being obtained with a membrane ultrafiltration having a cutoff threshold corresponding to a molecular weight of 300,000, as well as with a microfiltration membrane having a pore diameter of 0.1 ⁇ m.
- the tangential circulation speed of the clarified juice is adapted to the geometry of the micro-, ultra- or nanofiltration module used and may be of the order of 2 to 9 m / s, preferably 6 m / s.
- This circulation speed is regulated by the pump 10, it being specified that part of the filtered juice is brought back by a return line 11 a at the suction of said pump 10.
- the filtrate (permeate) from unit 11 is then routed through a conduit 12 into a storage tank 13 from which it is drawn off by a pump 14 to be brought to the head of a softening column 15 filled with a cation exchange resin, in particular a strong cationic resin, in the Na + and / or K + form , for example a resin from Rhom and Haas.
- a cation exchange resin in particular a strong cationic resin, in the Na + and / or K + form , for example a resin from Rhom and Haas.
- This column is provided, at its upper part, with a filtrate inlet 16 connected to the discharge of the pump 14 and, at its lower part, with a conduit 17 for softened filtrate outlet (content of Ca 2+ ions and / or Mg 2+ of the order of 10 to 50 ppm), the Ca 2+ and / or Mg 2+ ions present in the filtrate supplied at the head of the column (content of Ca 2+ and / or Mg 2+ ions of l (order of 300 to 3000 ppm) being retained by the resin during the progression of the filtrate through the column by displacing the Na + and / or K + ions of this resin.
- the softened filtrate discharged through line 17 then arrives in a tank 18 from which it is drawn off by a pump 19 to be brought into a concentration unit 20 which can be, for example, an evaporator such as a falling-stream evaporator.
