(3) use the nanofiltration membrane of molecular weight cut-off 220Da-500Da, under 10Bar-40Bar pressure, filtering and concentrating is carried out to described clear juice, obtain the clear juice of beet sugar manufacture after concentrated purification.
In the present invention, described " nanofiltration " is a kind of membrane separation technique, and its molecular weight cut-off is usually at about 150-1000Da, and the aperture of film is several nanometer, therefore, is called " nanofiltration ".
Wherein, in step (1), described in be suitable in the clear juice of beet sugar manufacture of nanofiltration, sucrose accounts for 10wt%-15wt%, moisture accounts for 84wt%-89wt%, and sucrose purity is 85wt%-92wt% (wherein, sucrose purity refers to that in juice clearly, sugar composition accounts for the weight ratio of soluble solids).
As described above, after two carbon full charge clarification and filtration process, the molecular weight of the moisture in clear juice and main non-sugar ingredient (comprising inorganic salt, nitrogenous substances, reducing sugar) is all starkly lower than the molecular weight of sucrose.Therefore, the material characteristic of clear juice system is suitable for adopting nanofiltration of the present invention to carry out purification to it concentrating.Although two carbon full charge fining process is prior art, in order to prepare the clear juice of the beet sugar manufacture being suitable for nanofiltration, two carbon full charge fining process is used to be preferred step.The clear juice of beet sugar manufacture obtained after the process of two carbon full charge fining process is the clear juice of beet sugar manufacture being particularly suitable for nanofiltration, because of but the approach of the clear juice of particularly preferred acquisition beet sugar manufacture of the present invention.
In step (2), preferably described juice temperature is reduced to from about 90 DEG C and is not less than 30 DEG C, be preferably reduced to 40 DEG C-45 DEG C.On the one hand, from technological angle, for avoiding causing unnecessary thermosteresis, cool the temperature to too low not preferred.On the other hand, consider from the filtering feature of nanofiltration membrane and the angle of stability, the temperature range be applicable to is 40 DEG C-90 DEG C, preferably 40 DEG C-60 DEG C, particularly preferably 40 DEG C-45 DEG C.
In step (3), when nanofiltration purification concentration, need the Nanofiltration Membrane Separation Technology using molecular weight cut-off and sucrose molecules amount to be close, while retaining sucrose, make water molecules and small molecules non-sugar ingredient impurity through nanofiltration membrane, thus realize the purification of clear juice and concentrate.If the molecular weight cut-off selected is excessive, then more polysaccharide can be caused to divide and to enter into through water through nanofiltration membrane, sugar loss is increased; If molecular weight cut-off is too small, then that can reduce non-sugar leaches ratio, reduces refining effect.Based on above-mentioned consideration, the molecular weight cut-off of described nanofiltration membrane is preferably 220Da-500Da, more preferably 350Da-450Da, further preferred 400Da.
To nanofiltration pressure, the common pressure range being suitable for nanofiltration technique can be used, be preferably between 10Bar-40Bar.If pressure is excessive, connecting tube is stressed excessive, can cause damage to equipment.Described filter pressure is preferably 10Bar-40Bar, more preferably 20Bar.
Fig. 2 represents the schematic diagram of a kind of embodiment that beet sugar manufacture clear juice membrane sepn operates.Present method adopts nanofiltration to process clear juice, on the one hand can by large quantity of moisture through, thus realize the pre-concentration of clear juice; On the other hand, then by the selection of molecular weight cut-off, make small molecular weight impurity (as reducing sugar, trimethyl-glycine etc.) selectivity that molecular weight ratio sucrose is little through, thus realize the purification to clear juice.
Described nanofiltration membrane is organic nanofiltration membrane or nanofiltration membrane, but considers from reducing costs with the angle of actual filtration effect, preferred rolling organic nanofiltration membrane or tubular organic nanofiltration membrane.
In a preferred embodiment of the present invention, the rolling organic nanofiltration membrane of molecular weight cut-off 400Da is used to carry out nanofiltration.
In step (3), gained trapped fluid total reflux to clear juice storage tank, because of containing small molecules non-sugar impurities in nanofiltration permeate, and sucrose purity lower (below 35wt%), therefore be used as beet water for cleaning after can collecting, also can be used as direct discharging of waste water.Consider containing small molecules non-sugar impurities in nanofiltration permeate, if be recycling in the sugar refining technology after beet cleaning, then follow-up still needs removes these small molecules non-sugar impuritiess, therefore, and is not suitable for carrying out such recycle.
In nanofiltration process, Membrane Filtration Flux can decline gradually.In order to can nanofiltration membrane be reused, preferably nanofiltration membrane is cleaned.Specifically, when Membrane Filtration Flux drops to about 70% of initial flux, can stop filtering, film is cleaned.Membrane cleaning flow process conventional in prior art can be adopted to carry out described Membrane cleaning.When the film pure water permeation flux after cleaning reach use first time pure water permeation flux more than 80% time, namely think that cleaning completes.
In order to ensure that concentrated purification process carries out continuously, method of the present invention preferably adopts many group nano-filtration membrane equipments to filter, so that the cleaning in turn of film device.
Clear juice is after nanofiltration purification is concentrated, and gained trapped fluid directly enters the drift of follow-up dilute juice sulphur and evaporative crystallization.
The invention still further relates to a kind of method for manufacturing sugar, described method comprises:
(1) the clear juice of beet sugar manufacture being suitable for nanofiltration is obtained;
(2) temperature of described clear juice is reduced to from about 90 DEG C is not less than 30 DEG C;
(3) use the nanofiltration membrane of molecular weight cut-off 220Da-500Da, under 10Bar-40Bar pressure, filtering and concentrating is carried out to described clear juice, obtain the clear juice of beet sugar manufacture after concentrated purification;
(4) the clear juice of described beet sugar manufacture obtained is carried out sulphur drift decolouring, evaporation concentration, crystallization, obtains sugar product.
By the integrated artistic of beet sugar manufacture, traditional sugar refining technology flow process and the process of producing sugar flow process after improving contrast as shown in Figure 3.As can be seen from Figure 3, sugar refining technology flow process of the present invention adds nanofiltration treatment process.Therefore, the change of this operational path to traditional sugar refining technology is less, and the difficulty applied is lower.
In tradition sugar refining technology, adopt multiple-effect evaporation that clear juice brix is concentrated into about 60Brix, this process is the main power consumption step in sugar refinery; But, adopt nanofiltration to carry out pre-concentration, effectively can reduce the energy consumption that subsequent evaporation is concentrated.The raising of sucrose purity in clear juice, can increase the percent crystallization in massecuite of sucrose in subsequent evaporation concentration technology, reduces molasses amount; According to Theoretical Calculation, when purity of clear juice value increases by 1%, sucrose yield can increase about 1.5%, and therefore the raising of purity of clear juice increases income significant to sugar refinery.
